Dear Participant:

We are pleased to be enclosing a complete three-volume  set  from  the  Conference
on General Aviation Airport Noise and Land Use  Planning.  Sponsored  by  EPA,
Office of Noise Abatement and Control, and conducted by the Georgia  Institute
of Technology, College of Architecture, the Conference  was  held  at the
University October 3-5, 1979.

Volume I contains summaries of each of the panel  sessions.  Volume  II contains
the prepared papers that were presented by the  speakers at  the Conference,  and
Volume III is the proceedings based on a transcription  over the  entire  three
day period.

We believe this Conference has been very significant, addressing a major
subject area that has previously been overlooked.  The  success of the
Conference is attributable to the excellent quality  and enthusiasm  of the
participants.

Again, thank you for your participation.  We hope  that  similar conferences  in
the future will be held to deal further in depth  with this  important subject
matter.  You will be notified of any such future  plans.
                                               Sincerely,

         GENERAL AVIATION  IN  THE UNITED  STATES:
                PAST,  PRESENT,  AND FUTURE
                     JOHN E,  WESLER
                   WlBMTRSTTOf
ANY DISCUSSION OF GENERAL AVIATION MUST BEGIN WITH SOME
DEFINITION OF THE TERM,   "GENERAL AVIATION" IS NOT STRICTLY
DEFINED IN THE FEDERAL AVIATION REGULATIONS, WHICH ARE
PROMULGATED BY THE FEDERAL AVIATION ADMINISTRATION (FAA)
IN ORDER TO REGULATE AIR COMMERCE, PROMOTE, ENCOURAGE, AND
DEVELOP CIVIL AERONAUTICS, AND CONTROL THE NAVIGABLE
AIRSPACE OF THE UNITED STATES,
AS NORMALLY ACCEPTED, "GENERAL AVIATION" REFERS TO ALL
CIVIL AIRCRAFT OPERATED  IN THE UNITED STATES EXCEPT
THOSE OPERATED UNDER PARTS 121 AND 127 OF THE FEDERAL
AVIATION REGULATIONS--THAT IS, ALL LARGE AIRCRAFT AND
HELICOPTERS USED  IN SCHEDULED AIR CARRIER OPERATION,  THUS,
"GENERAL AVIATION"  INCLUDES SUCH  USES AS AIR TRAVEL  CLUBS
WITH BOEING 707S  AND CONVAIR  880S, AIR TAXI AND COMMERCIAL
OPERATORS  OF  SMALL  AIRCRAFT,  AIR  CARGO CARRIERS,  AND BUSINESS
CORPORATE  AIRCRAFT,  IN ADDITION TO THOSE NORMALLY THOUGHT  OF
AS" RECREATIONAL  AIRCRAFT, ALONGSIDE THE SMALL SINGLE-ENGINE
PROPELLER-DRIVEN PIPER CUB  RESIDES A BOEING 707,  CLASSIFIED
AS A  "GENERAL AVIATION"  AIRPLANE,

-------
FOR OUR PURPOSES THIS MORNING,  I  BELIEVE WE ARE MORE
INTERESTED IN THE TYPES OF AIRCRAFT WHICH OPERATE INTO
AND OUT OF THE SMALLER AIRPORTS AROUND OUR COUNTRY,
ALTHOUGH STRICTLY SPEAKING, MANY LARGER JET-POWERED  AIR-
PLANES ARE INCLUDED IN THE GENERAL AVIATION CATEGORY,
THEY ARE NOT OF INTEREST TO US HERE BECAUSE THEY OPERATE
ALMOST ENTIRELY OUT OF MEDIUM AND LARGE HUB AIRPORTS,   WE
MEAN TO CONCENTRATE ON SMALLER AIRCRAFT,

SMALLER GENERAL AVIATION AIRCRAFT DOMINATE THE U.S.  CIVIL
AIR FLEET,  THERE ARE APPROXIMATELY 193,000 GENERAL AVIATION
AIRCRAFT IN USE TODAY, COMPARED WITH LESS THAN 2,400 AIR
CARRIER AND AIR CARRIER TYPE AIRCRAFT,  GENERAL AVIATION
AIRCRAFT:
     -  ARE FLOWN BY 798,800 ACTIVE PILOTS
     -  WILL FLY 39 MILLION HOURS THIS YEAR
     -  MAKE SOME 54 MILLION RECORDED OPERATIONS AT
        AIRPORTS WITH FAA TOWERS
     -  MAKE APPROXIMATELY 17 MILLION  INSTRUMENT
        OPERATIONS
GENERAL AVIATION GROWTH WILL CONTINUE AT A  HIGH  RATE,   OVER
THE NEXT 12 YEARS-IN 1991-WE FORECAST THAT THERE  WILL
BE:
     -  304,000 GENERAL AVIATION AIRCRAFT--AN  ANNUAL
         INCREASE OF  3,9 PERCENT

-------
     -   1,110,700 ACTIVE PILOTS—AH ANNUAL GROWTH RATE
        OF  2.8  PERCENT
     -   64  MILLION  HOURS FLOWN--AN ANNUAL INCREASE OF
        4,2 PERCENT
     -   NEARLY  76 MILLION  RECORDED OPERATIONS AT
        AIRPORTS WITH FAA  TOWERS-AN ANNUAL GROWTH
        RATE OF 3,0 PERCENT
     -   OVER 31 MILLION INSTRUMENT OPERATIONS—AN ANNUAL
        GROWTH  RATE OF  5,1 PERCENT
     -   FASTER-THAN-AVERAGE  GROWTH IN  CORPORATE BUSINESS
        FLYING
     -   SLOWED  GROWTH  IN RECREATIONAL  FLYING DUE TO
        CONTINUALLY RISING FUEL COSTS
THESE STATISTICS DISPLAY ONLY A PORTION  OF THE GENERAL
AVIATION ACTIVITY  IN THIS COUNTRY,  THE  OPERATIONS LISTED
ABOVE ARE ONLY  THOSE AFFECTING THE FAA'S WORKLOAD-THAT IS,
OPERATIONS AT AIRPORTS  WITH  FAA TOWERS,   AT  THE BEGINNING
OF THIS YEAR, THERE WERE 14,574 AIRPORTS IN  THE U,S,, OF
WHICH 13,853 HANDLED ONLY GENERAL AVIATION AIRCRAFT, AND
730 HANDLED BOTH  GENERAL AVIATION AND  CERTIFIED AIR  CARRIER
OPERATIONS,  ONLY 428 OF THESE AIP.PORTS  HAVE FAA  TOWERS,
THUS, THE TOTAL NUMBER OF GENERA! AVIATION TAKEOFFS  AND
LANDINGS IN THIS  COUNTRY IS  OPEN TO QUESTION,

-------
THE FORECASTED GROWTH IN GENERAL AVIATION ACTIVITY
PORTENDS GROWING  PROBLEMS AT THE SMALLER AIRPORTS WHICH
MUST HANDLE THESE OPERATIONS.  THE SHEER INCREASE IN THE
NUMBER OF TAKEOFFS AND LANDINGS WILL INCREASE THE MBER
OF NOISE EVENTS.  ADDING TO THE ABSOLUTE GROWTH AT THE
SMALLER AIRPORTS VilLL EE THE LESSENED USE OF LARGER HUB
AIRPORTS BY GENERAL AVIATION AIRCRAFT.  THE POTENTIAL
DANGERS OF MIXING OPERATIONS AT LARGER AIRPORTS HAS
TRAGICALLY ILLUSTRATED LAST YEAR AT SAN DIEGO, NITH THE
MID-AIR COLLISION BETWEEN AN AIR CARRIER 727 AMD A SMALL
SINGLE-ENGINE PROPRELLER-DRIVEN AIRPLANE.  AS PART OF OUR
PROGRAM TO REDUCE THIS RISK, THE FAA HAS ACCELERATED ITS
IMPROVEMENTS OF SATELLITE, OR RELIEVER AIRPORTS NEAR MAJOR
HUBS.  AS THE NAME INDICATES, SATELLITE AIRPORTS WILL HAVE
SUITABLE RUNWAYS, APRONS, CLEAR ZONES, AND NAVIGATIONAL
EQUIPMENT TO ATTRACT GENERAL AVIATION AND TRAINING OPERATIONS
AWAY FROM THE LARGER AIRPORTS.  THUS, MANY SMALLER AIRPORTS
WILL SEE SIGNIFICANT  INCREASES  If] OPERATIONS DURING THE
COMING YEARS.
THE FEDERAL POLICY REGARDING AVIATION NOISE ABATEMENT WAS
STATED  IN 1976,   ESSENTIALLY,  IT WAS  OUR  THEME AT  THAT  TIME--
AND REMAINS THE SAME  TODAY--THAT AVIATION NOISE ABATEMENT  IS

-------
A SHARED RESPONSIBILITY AMONG ALL ELEMENTS OF THE AIRPORT
COMMUNITY,   THE FEDERAL GOVERNMENT MUST:
     -  CONTROL AIRCRAFT NOISE AT THE SOURCE--THE AIRPLANE
        ITSELF
     -  CONTROL AIRCRAFT OPERATIONS AMD MANAGE THE
        NAVIGABLE AIRSPACE SO AS TO MINIMIZE NOISE
        IMPACTS
     -  PROVIDE FUNDING TO PERMIT AIRPORT NOISE ABATEMENT
        PROJECTS
     -  SUPPORT AND ENCOURAGE RESEARCH AND DEVELOPMENT OF
        NOISE ABATEMENT TECHNOLOGY
THE FAA HAS MET ITS RESPONSIBILITIES:
     -  NOISE STANDARDS LIMIT THE NOISE LEVELS OF NEW-
        DESIGN AND NEW-PRODUCTION AIRCRAFT, INCLUDING
        SMALL PROPELLER-DRIVEN MODELS
     -  OPERATIONS AT FAA-CONTROLLED AIRPORTS ARE
        TAILORED TO MINIMIZE NOISE IMPACTS
     -  FAA PROVIDES FEDERAL FINANCING OF AIRPORT
        PROJECTS FOR NOISE ABATEMENT PURPOSES, AMD
        WE  HAVE PROPOSED NEW LEGISLATION TO EXTEND
        ELIGIBILITY TO SOUNDPROOFING OF PUBLIC BUILDINGS
        NEAR AIRPORTS, AND NOISE MONITORING EQUIPMENT
     -  FAA WORKS CLOSELY WITH THE NATIONAL AERONAUTICS
        AND SPACE ADMINISTRATION TO PUSH NOISE ABATEMENT
        TECHNOLOGY

-------
6
BUT THE FEDERAL EFFORTS ALONE CAM NEVER SOLVE THE
AVIATION NOISE PROBLEM,  AIRCRAFT WILL NEVER BE SILENT,
NO MATTER HOW ADVANCED THE TECHNOLOGY, THERE WILL REMAIN
A RESIDUAL NOISE IMPACT, WHICH MUST BE ATTACKED BY THE
OTHER ACTORS IN THE AIRPORT GAME:
     -  AIRPORT OPERATORS ARE RESPONSIBLE FOR THE
        DAY-TO-DAY OPERATIONS AT THEIR AIRPORTS,
        AND ARE FINANCIALLY LIABLE FOR ANY DAMAGES
        WHICH RESULT,  INCLUDING NOISE DAMAGES
     -  STATE AND LOCAL GOVERNMENTS ARE RESPONSIBLE
        FOR LAUD-USE CONTROL AND ZONING, AND FOR
        PUBLIC EDUCATION AND AWARENESS OF THE AIRPORT
        NOISE CONDITIONS
     -  AIRCRAFT OPERATORS ARE RESPONSIBLE FOR THE
        PROPER CONTROL OF THEIR AIRPLANES, FLYING
        THEM SAFELY  IN A MANNER LEAST  INTRUSIVE TO
        AIRPORT NEIGHBORS
ALTHOUGH THE SUBJECT OF OUR MEETING HERE TODAY  IS GENERAL
AVIATION AIRPORT NOISE AND LAND-USE PLANNING,  I WOULD LIKE
TO CONCENTRATE FIRST ON THOSE THINGS  WHICH AN AIRPORT
PROPRIETOR CAN DO TO LIMIT NOISE AT HIS OR HER  AIRPORT
AND THUS MINIMIZE THE  RESIDUAL JOB LEFT TO THE  LAND-USE
PLANNERS,  RESTRICTING LAND USES FOR  NOISE COMPATIBILITY

-------
PURPOSES IS AN AGONIZING TASK,   IN MANY CASES,  IT IS AN
IMPOSSIBLE TASK IF AIRPORT SURROUNDINGS ARE ALREADY
DEVELOPED IN AN INCOMPATIBLE MANNER,   TYPICALLY,  LAND-
USE PLANNING IS ONLY FEASIBLE AS A MEANS OF PROTECTING
FURTHER NOISE IMPACTS, RATHER THAN CORRECTING THOSE WHICH
ALREADY ARE PRESENT,  THE LESS LAND AREA AFFECTED, THE
BETTER--IN EITHER CASE,
AN AIRPORT OPERATOR IS IN AN UNCOMFORTABLE POSITION-LEGALLY
RESPONSIBLE FOR NOISE DAMAGES RESULTING FROM THE OPERATION
OF THAT AIRPORT, BUT OFTEN APPARENTLY WITH LITTLE CONTROL
OVER THOSE OPERATIONS,  THE FEDERAL GOVERNMENT HAS PRE-
EMPTED CONTROL OVER THE NOISE GENERATOR-IKE AIRPLANE--BOTH
ITS INHERENT NOISE PRODUCTION AND THE MANNER IN WHICH IT IS
FLOWN,  SO WHATS LEFT?
ONE AVAILABLE MEANS IS THE CONTROL OR RESTRICTION OF THE
TYPES OF AIRPLANES WHICH MAY USE AN AIRPORT, BASED ON THE
NOISE CHARACTERISTICS OF THOSE AIRPLANES,  CURFEWS ARE ONE
READILY-APPARENT EXAMPLE, EITHER BY CLOSING THE AIRPORT
COMPLETELY AT NIGHT, OR BY RESTRICTING AIRPORT USE TO
"QUIET" AIRPLANES DURING CERTAIN HOURS,   RESTRICTING  USE
OF AN AIRPORT THROUGH A BAN ON JET-POWERED AIRCRAFT,
BECAUSE OF NOISE,  IS  NOT PERMISSABLE,  SO-CALLED  "JET BANS"
HAVE BEEN  RULED TO  BE DISCRIMINATORY BY THE COURT IN  THE

-------
RECENT SANTA MONICA CASE,  SINCE IT WAS SHOWN  THERE  THAT
SOME JET AIRCRAFT ARE ACTUALLY QUIETER IN OPERATION THAN
SOME PROPELLER-DRIVEN AIRCRAFT,
IF THE REASON FOR USE-RESTRICTIONS AT AN AIRPORT IS NOISE,
THEN flOISE LEVELS CAN BE EMPLOYED TO RESTRICT USE,   THE FAA
HAS PUBLISHED ADVISORY CIRCULAR 36-3, DATED MAY 29, 1979,
LISTING IN DECENDING ORDER OF NOISE LEVEL MANY AIRCRFT
TYPES AND MODELS,  THESE NOISE LEVELS ARE BASED ON  STANDARDIZED
TESTS, FOLLOWING THE PROCEDURES DEFINED IN THE FAA'S NOISE
STANDARDS, 14 CFR 36,  LEVELS ARE TABULATED FOR ALL AIRCRAFT,
FOR WHICH RELIABLE DATA ARE AVAILABLE, AT THREE LOCATIONS-
THE TAKEOFF, SIDELINE, AND APPROACH LOCATIONS SPECIFIED IN
THE NOISE REGULATIONS,  THUS, RELIABLE, COMPARABLE, STANDARDIZED
NOISE VALUES ARE READILY AVAILABLE FOR GENERAL USE,  AN AIRPORT
OPERATOR MAY THEN LIMIT THE USE OF AN AIRPORT TO AIRCRAFT
WHICH GENERATE NO MORE THAN—FOR EXAMPLE--85 A-WEIGHTED
DECIBELS AS MEASURED DURING TAKEOFF UNDER THE STANDARDIZED
PROCEDURES OF H» CFR 36, AND HAVE AVAILABLE A NONARBITRARY
AND NONDISCRIMIHATORY BASIS FOR DETERMINING WHICH TYPES OF
AIRCRAFT ARE ADMISSABLE AND ACCEPTABLE AT THAT AIRPORT,  THE
ACTUAL NOISE LIMIT SELECTED MUST, OF COURSE, DEPEND ON THE
DEGREE OF NOISE PROTECTION JUSTIFIED AT AN AIRPORT,  AND, OF
COURSE, AN AIRPORT OPERATOR WILL NEED TO EXAMINE CAREFULLY
JUST WHAT SUCH A RESTRICTION WILL DO TO THOSE AIRCRAFT
OPERATORS THAT HIS OR HER AIRPORT SERVES,

-------
IT IS OFTEN TEMPTING TO INSTALL A MICROPHONE OFF THE  RUNWAY
OF AN AIRPORT, AND LIMIT THE USE OF AN AIRPORT BASED  ON
ACTUAL NOISE MONITORING,  ASIDE FROM THE TECHNICAL COMPLICATIONS
AND EXPENSE OF SUCH AN APPROACH, THE FAA OPPOSES SUCH
RESTRICTIONS ON THE BASIS OF SAFETY,  PILOTS-AMD ESPECIALLY
LESS EXPERIENCED PILOTS-MAY BE TEMPTED TO "BEAT THE  BOX"  IN
SUCH INSTANCES, BY FLYING IN AN UNSAFE MANNER IN ORDER TO
REDUCE NOISE OVER THE MONITORING POINT,  IN ADDITION, CON-
STANTLY CHANGING PROPAGATION AND METEOROLOGICAL CONDITIONS
WILL CAUSE NOISE LEVELS AT A GIVEN POINT TO CHANGE FROM  DAY-
TO-DAY, EVEN THOUGH THE SAME AIRCRAFT IS FLOWN IN EXACTLY
THE SAME MANNER,  THUS, A PILOT IS NEVER CERTAIN THAT HE OR
SHE WILL MEET A SET MEASURED LEVEL EACH TIME HE OR SHE FLIES,
AND MAY BE TEMPTED TO ALTER THE FLIGHT PROCEDURE "JUST TO  BE
SURE",  I BELIEVE THAT THE STANDARDIZED NOISE LEVELS
TABULATED IN ADVISORY CIRCULAR 36-3 ARE A BETTER BASIS FOR
RESTRICTING AIRCRAFT USE AT AN AIRPORT, THAN ARE MONITORED
SINGLE-EVENT LEVELS,
IN SUMMARY:
     -  GENERAL AVIATION ACTIVITY IS GROWING, AND WILL
        CONTINUE TO GROW IN THE FORESEEABLE FUTURE
     -  ALTHOUGH THE INDIVIDUAL NOISE LEVELS OF NEW
        GENERAL AVIATION AIRCRAFT WILL BECOME QUIETER
        AS THE FAA'S NOISE STANDARDS BECOME INCREASINGLY
        EFFECTIVE, SHEER VOLUME OF ACTIVITY WILL CONTINUE
        NOISE PROBLEMS AT SOME GENERAL AVIATION AIRPORTS

-------
10
        LAND-USE CONTROLS AND ZONING ARE DIFFICULT TO
        IMPOSE, AND REPRESENT ESSENTIALLY THE LAST
        RESORT IN AVIATION NOISE ABATEMENT
        THERE ARE CONSTITUTIONAL AND PRACTICAL MEANS
        FOR RESTRICTING AIRPORT USE FOR NOISE CONTROL
        PURPOSES

                           OCTOBER 3, 1979

     Good morning.  I  want to welcome all of you to this Conference
on general aviation airport noise and land use planning.  We in EPA
hope that this Conference will play a major role in charting the course
in general aviation development in the future.  Our focus, of course,
is noise produced by general aviation aircraft and its impact on
neighborhoods surrounding our Nation's airports.  Clearly, general
aviation does produce noise in neighborhoods across this country.
But how much of a problem does this noise present?
          Will it get worse in the future?
          Are there adequate remedies that could be adopted by affected
          communities?  By the manufacturers of general aviation aircraft?
          By the general aviation pilots and owners?
          Is there a need for Federal regulation in this area?
     If the answer to any of these questions is "yes," how soon must
action be taken?
     These are some of the questions I hope we will talk about during
this three day conference.

-------
     I would like to take a moment to thank Dr.  Clifford R.  Bragdon of
Georgia Tech for organizing this conference and acting as our Conference
Host.  Cliff is well known to many of you for his leadership in the
field of noise and land use planning.  He seemed the perfect choice of a
person who could bring us all together to discuss these serious matters
in a relaxed and non-adversarial atmosphere.
     The U.S. Environmental Protection Agency has been in the noise
business since the passage of the Noise Control Act of 1972.  That Act
laid out a Congressional policy "to promote an environment for all
Americans free from noise that jeopardizes their health and welfare."
That Act directs EPA to design and carry out a national program to abate
and control environmental noise.  Because of the Federal Aviation Admini-
stration's active role in the aviation noise area, EPA was given an
advisory role with regard to the regulation of aviation noise and a
regulatory role with regard to all other environmental noise sources.
     Those of you who have followed the aviation noise area during the
last few years know that we in EPA have focused most of our aviation
noise activities on the problem of the commercial fleet.  We have made  a
number of regulatory proposals to the FAA and have been actively  involved
in the promotion and implementation of noise abatement planning at the
Nation's commercial air carrier airports.- Significant progress has been
made in this area.  But, of course, much still remains to be done.

-------
                                                                       3.
     The reauthorization of the Noise Control  Act which is now pending
before Congress requires EPA to prepare a five-year plan for its activities
in the coming years.   The mandate is explicit in requiring that EPA
update its 1973 Report To The Congress On Aviation Noise as part of this
five-year planning exercise.  One of the major purposes of this Conference
is to provide guidance to us in EPA about our activities in the general
aviation area during the next five years and the years beyond.
     We have been impressed with the difficulty in the atr carrier area
of trying to control  aviation noise in a situation where the problem is
already severe and the order of the day is abatement and retrofit rather
than prevention.  One needs only to read the newspapers to realize that
noise has become a real albatross around the neck of the commercial air
transportation system and a major public nuisance for neighborhoods around
most of our major airports.   The noise problem from general aviation  is
clearly not this acute, and yet the rapid growth projected for  the
future for general aviation raises the question whether preventative
steps are needed now in order to avoid serious political  and economic
constraints on the growth of this valuable part of the Nation's air
transportation system.
     By its very nature, prevention of a future noise  problem  at general
aviation airports would  involve many  actors, not just  the Federal  Government.
In fact, the major burden for prevention would most probably  fall  on  the
private sector and States and localities.  Those who would expect  the
Federal Government to  solve this problem would  not be,  in my  view, very
good students of contemporary political  science.   Thus,  although we in

-------
EPA have taken the Initiative to call  this conference,  and we want to
see what role we might play in this area,  the focus of  this conference
must be much broader:  If a preventative program is needed, what
mutually supportive roles might a whole variety of parties take in
this effort?  We in EPA are prepared within the limits  of our statutory
authority to draft regulations for consideration by FAA in this area,
to give financial assistance under the new Quiet Communities Act to
local communities and States for airport noise abatement planning, and to
continue to help to bring together interested parties for discussion and
possible agreement on appropriate courses of action.  Deciding whether
or not EPA plays such a.role, however, is less important for this
Conference than identifying whether or not noise from general aviation
is a problem today or potential problem for the future and laying out
what actions might be appropriate to minimize this problem.
HEALTH AND WELFARE
     Any assessment of the potential seriousness of the ge^neeaY aviation
noise problem must begin, we believe, with an assessment of the effects
of noise on people.  It is always surprising, I think, to people who
come to review this field from other walks of life, that so much is
already known about the effects of noise on people.  Although noise as
an environmental pollutant is much less in the forefront of popular
understanding and support than, say, air and water  pollution, noise is
the most pervasive of our environmental pollutants  and it  has, I believe,
the longest history.  Long before man  knew that the water  and air  he was
drinking and breathing were bad for his health, he  knew the difference

-------
                                                                         5.
between sound and noise, and he knew he didn't  like  the  noise.   Noise  is
the one pollutant for which nature gave us  built-in  monitors.   In addition,
the fear of a loud noise is one of two fears  we are  born with,  and our
bodies still react to a loud noise even though  we may consciously think
we're ignoring it.
     This natural aversion to noise has been  borne out by subsequent
scientific research.  Our automatic response  to noise has turned out to
be quite sensible, but for far more subtle reasons than we originally
suspected:
     Most of us today are, of course, aware of the impact of noise on
our hearing.  Millions of Americans today have severe hearing losses
because of their exposure to noise.  What is  perhaps not known by most
Americans, however, is that people risk losing their hearing in the
presence of much lower exposure levels than they would ever suspect are
hazardous.  On the basis of the latest scientific evidence, we in EPA
have established an average level of 70 decibels over a 24-hour period
as the level necessary to protect the public from significant adverse
effects on their hearing, with an adequate margin of safety. Those who
are exposed to higher levels than this for 40  or more years run a risk
of losing some of their  hearing.  Needless to  say, millions of Americans
in this country are exposed to levels of noise significantly above  70
decibels, particularly  in  their employment,  but also around some  of our
major  airports.
     Of course,  noise  control  ordinances across the country and  lawsuits
against airport  proprietors  today are based  not so  much on a concern  for   ,
hearing  loss  on  the part of the public, but  on something more  fundamental:
people just do not  like noise.   It is hard to  find  words to  characterize
this  aversion to noise.   The  traditional word  of art used by  the scientific

-------
                                                                         6.

community is "annoyance,"  but generally we all  use the word  "annoyance"
to signify something which is not very serious.  Those of you  who have
dealt with angry citizens  around airports know  that they certainly do
not regard aviation noise  as some insignificant irritant in  their
lives, so the word annoyance is certainly a misnomer.  As the  scientific
community has tried to quantify this type of reaction, they  have searched
for an understanding of its causes.   They have  found,  as you would
expect, that environmental noise interferes with normal  conversation and
a number of relaxing and educational activities on which people put a
great deal of value. It also disrupts sleep, and if a  person lives in an
environment which is continually impacted each  night by  noise, such as
near a major airport, the disruption of sleep can become a serious
health problem.  Based on these impacts, EPA has identified a day-night
average level of 55 decibels as the level necessary to avoid most of
these effects.
     But recently, scientists have been focusing on an even more fundamental
aspect of noise.  The "annoyance" reactions that scientists have identified
so far may only be the tip of the iceberg, when it comes to the real
health effects of noise.  Noise is a stressor  and the body responds to
stress in many subtle ways that we are not conscious of.  Noise triggers
an automatic response in our bodies which is not controlled by our
conscious minds.  This probably stems from the fact, as  I mentioned,
that fear of a loud noise is one of the two fears that we are bom with
and we never forget it.  Outwardly, we may seem calm in  the presence of
noise, but internally our heart rate goes up,  our blood  pressure  goes
up, adrenalin is secreted and our bodies prepare  for the "expected"
assault.

-------
     We in EPA are currently sponsoring a study with Rhesus monkeys at
the University of Miami in conjunction with the National  Institutes of
Health.  This study stems from the fact that there are over 40 epidemiological
studies from foreign countries which show a relationship  between noise
and cardiovascular disease.  This preliminary monkey study has shown
that after several months of noise exposure which is similar to that
received by millions of working Americans today, the monkeys have
sustained an elevated blood pressure of 30% even after the noise source
was removed.  It is too early to draw conclusions from this preliminary
experiment and further research is necessary, but if noise is in fact
tied to elevated blood pressure and possible hypertension, the control
of noise may become one of the foremost public health programs in the
country since hypertension is directly linked to heart disease and
stroke. These two diseases alone account for 48% of the deaths in this
country every year.
     In short, noise is not something to be laughed at or to tell our-
selves that we can get used to.  It is a serious health problem, and the
evidence is tending to indicate that the effects could be more serious
and much more wide-ranging than we ever imagined in the past.
     From the point of view of an airport proprietor, it may matter less
exactly what the health effects of noise are and more that angry airport
neighbors can prevent an airport's expansion and improvement.  Their
lawsuits and political activity could in the future significantly  slow
if not stop the growth of  the air transportation system.  Rightly  or
wrongly, citizens in this  country are becoming  less and less  tolerant of
public officials who nake  pronouncements that airport expansion  is  for
the public good and   tat private individuals must give up their  property
rights and suffer in order that others might fly or otherwise have the
convenience of the airport.

-------
     So from many perspectives,  noise is  an environmental  pollutant  to
be reckoned with, and it behooves  us  to examine  the  extent to which
noise is already a serious problem around some of our general aviation
airports and whether or not the  growth of the industry will  exascerbate
this problem significantly in the  coming  years.
AVIATION NOISE BACKGROUND
     What do we know about the noise  characteristics of  the general
aviation fleet?  Well, putting aside  all  military aircraft, there are
approximately 185,000 aircraft registered for operation  in the  United
States.  Only about 3,000 of these civil  aircraft are owned and operated
by air carriers as part of the commercial air transportation system.
The rest are operated as general aviation aircraft by individuals,
businesses, and governments.  Most of these aircraft, as you know, are
propeller driven rather than jet powered, although jets  are gaining a
larger share of the general aviation fleet every year.
     These 185,000 civil aircraft operate into approximately 14,000
airports in this country.  Half of these 14,000 airports are open to the
public and about 600 of these are certificated for air carrier operations.
It is estimated that today over 130 million operations take place annually
at public use general aviation airports with daily operations varying
up to about 500 operations.  The FAA estimates that operations
of these public use airports will  almost double to 220 million annual
operations by 1987 and that the number of general aviation aircraft
during this period will increase from 185,000 to over 240,000 aircraft
in the same time period.

-------
                                                                        9.
     Most of the country's attention to airport noise  has  been  focused
on about 100 of the larger air carrier airports.   Our  analysis  of these
air carrier airports indicates that In 1975 approximately  6 million
people were exposed to noise levels of a day-night average of 65 decibels
or greater due to air carrier aircraft alone.   A number of steps have
been taken recently which will bring the number of people  exposed to these
high levels of noise down over the next several years, with the greatest
benefit occurring sometime around the year 1985 when the retrofit/
replacement rule will be fully implemented.  Unfortunately, because of
the growth in the size of the commercial aircraft fleet and increased
operations, we can expect the number of people exposed to start going
back up significantly after that date.  Consequently,  we in EPA are
actively encouraging further steps to reduce exposure to commercial
aviation noise around our Nation's airports.
     We know very Tittle about the noise problem at the rest of these
13,000 or so airports which serve the general aviation fleet.  We also
know very little about the contribution of general aviation to the noise
problem at our major air carrier airports.  We are undertaking studies
at the present time to predict the noise exposure from these aircraft
both now and in the future, but the universe of aircraft and airports
are so large that it will be  sometime  before we have  a fully comprehensive
national view of the scope of the problem.  Surely, general aviation
noise is a problem at some airports, but we at EPA have no  pre-conceived
ideas about the severity of general aviation noise and to what extent it
may or may not be a national  problem.   We  cannot  look at just  the  aircraft
or their operations; we must  consider  the  airport community as well.  If

-------
                                                                        10.
land use near the airport has evolved w.sely,  there  may  be  little  or no
disturbance for the community.  On the other hand, ambient  noise levels
in communities surrounding general aviation airports may be significantly
lower than around our major commercial air carrier airports.  Thus,
general aviation noise may be more intrusive for people  living around
the airport because it occurs against such a low ambient noise level.
Consequently, the fact that general aviation aircraft are quieter than
commercial jets is no reason for complacency.   Thus, the possible noise
problem associated with general aviation is not just a technological
matter. There are socio-economic and environmental  implications which
must be considered as well.
     We are anxious to hear  from those of you attending this conference
concerning the extent which you believe, based on your own experiences,
that general  aviation  is  a problem today or will be  one in the  future.
This will  help guide future  studies  by the Federal  Government  in  this
area and  give us  all a sense of perspective on general  aviation noise.
WHAT CAN  BE  DONE ABOUT GENERAL AVIATION NOISE
      If general  aviation noise is today or will  be  in the  future  a
serious problem  for this country, what can  be done  about it?  It  will
come as no surprise to any of us  that there is  no single solution to a
problem as complex as  aviation noise. Our experience  in the commercial
aviation  noise area has  shown that any realistic solution  to the  problem
must combine actions by  a variety of parties, all  taken in coordination
with each other. Needless to say, orchestrating such a control program
 is very difficult, particularly when large investments have already been
 made on the basis of the status quo.  That is why working on the general

-------
                                                                             11.
aviation noise problem before it becomes  a national  crisis  is  attractive.
Prevention is usually much cheaper and much easier to bring about politically
than retrofit and abatement.   Instead of making investments obsolete as
we must do in some cases in the commercial aviation area,  a preventative
program might be able to focus future investments with little additional
costs involved.
     When people talk about quieting any aviation problem, they usually
think first about abating the source of the noise, which in this case
are the general aviation aircraft themselves.  Some steps have already
been taken by the aircraft industry to produce quieter aircraft.  For
instance, it is no longer possible to talk about "quiet" propeller
aircraft and "noisy" jets.  Some of our new jet aircraft today are
quieter than propeller  aircraft, and hopefully, quieter operation is the
trend of the future  for both  types of aircraft.  NASA is conducting
research with assistance  from EPA and FAA to develop quieter  propeller
driven and jet powered  general  aviation aircraft.   We are  hopeful that
some technological advances,  if only small ones, will result.  Of course,
there is no  automatic  link up between technological  improvements  in  the
 laboratory and the incorporation of  such  improvements  in-the  aircraft  of
 the future.  One  of  the very  difficult policy  questions for any  person
 in a Federal  regulatory agency such  as  EPA or  FAA is  the  extent  to  which
 the manufacturers can  be  expected to aggressively move  ahead to  incorporate
 new technology and to  develop new technology of their own instead of
 waiting to be forced to do so through some type of government regulation.

     Quieting the source of the noise has proven to be In and of Itself
insufficient to solve the commercial  aircraft noise problem and may well
prove to be so in the general  aviation area as well.  Ways in which the
aircraft are flown and the way in which airports are developed and
expanded can have a major influence over the amount of noise exposure in
the neighborhoods surrounding general aviation airports.   New takeoff
procedures incorporated now In an FAA advisory circular will provide
considerable relief to airport communities surrounding air carrier
airports in the future if the circular is complied with by-the air
carriers.  Similar improvements in takeoff or landing procedures might
provide some relief from general aviation aircraft also.
     And then there is land use control.  This country has been notoriously
unsuccessful in controlling the land use around airports  in  the past.
Even an airport as modern and advanced as Dallas/Ft. Worth is now beginning
to suffer from encroachment by residential neighborhoods.  Communities
that once vowed that  they would hold fast to decisions to ban incompatible
land uses are now caving in to the economic pressures  to  allow  residential
development  in areas  impacted by  the airport noise.  Thus, we can expect
that even our airports which are  built out  in  the  countryside will  soon
be subject to lawsuits by  citizens who are  outraged by the  increasing
noise  coming from these major  facilities.   We  need to  seek  stronger and
more effective methods for controlling  land use around commercial  airports.
The question for us  at this Conference  this week is whether such  advances
can be pioneered and  perfected perhaps  in  the  general  aviation  area
where  economic pressures  today are  not  quite  as great as they are around
commerical airports  but where  the need  in  the  future may be just as great.

     We have In the audience for this Conference people who can give us
a good perspective on the potential for these various means of dealing
with general aviation.  We have here representatives from Federal, State
and local governments, from the aviation industry, airport operators,
aircraft operators, aircraft manufacturers, representatives of environmentally
concerned groups, neighborhood representatives, leaders of the real
estate and lending institutions of our country, and spokesmen of the air
carrier airports and military airports.  Many of these groups have
already had unique experiences in dealing with general aviation airport
noise.  Some have been involved in the adoption of regulations concerning
general aviation airport usage.  Some have seen these regulations
struck down or are now involved in litigation concerning aviation regulations.
All of us would like to share in each other's experiences.  From this
exchange, I hope there will be a mutual benefit.  Speaking for EPA, we
hope to gain added insight into ways in which all of us can work together
in the years to come to deal with  this problem.
     So, I  urge all of you to make your views  heard.   Is  there a general
aviation problem today or will there be one  in  the future  and  if so,
what is  its extent.  Are there ways of controlling this noise  in the
future and  how effective would each of these methods  be?   What actions
need to  be  taken by some or all of us to bring  about  these solutions?
In order to make this Conference a working Conference and not  just  a  set
of lectures, we restricted the total number  of  participants.   In many cases,
you may  be  the only person at the  Conference with a  particular perspective.
So please take an  active role  in these discussions.   Express your views so
that they may affect  the conclusion  of the Conference and thereby the
policies and actions  of all of us  in the future.   We in EPA look  forward to
working  with all of you during  the next three  days.

              Department  of  Defense  Instruction

SUBJECT:     Air Installations Compatible  Use  Zones

References:   (a)  Department of the Air Force  Manual  86-8,  "Airfield
                    and Airspace Criteria,"  November  10,  1964
             (b)  Department of the Navy Publication,  NavFac P-272,
                    "Definitive Designs for  Naval Shore  Facilities,"
                    July 1962
             (c)  Department of the Navy Publication,  NavFac P-80,
                    "Facility Planning Factor  Criteria for  Navy  and
                    Marine Corps Shore Installations"
             (d)  through (j), see  enclosure 1.

A.  PURPOSE

    This Instruction:   (1) sets forth Department of Defense policy on
achieving compatible use of public  and private lands  in  the vicinity of
military airfields;  (2) defines (a) required restrictions on  the uses
and heights of natural and man-made objects  in the vicinity of air
installations to provide for safety of flight  and to  assure that people
and facilities are not concentrated in areas susceptible to aircraft
accidents;  and (b) desirable restrictions  on land use to assure  its
compatibility with the characteristics, including noise,  of air  instal-
lations operations;  (3) describes the procedures by which Air  Installa-
tions Compatible Use Zones (AICUZ)  may be  defined; and (4)  provides
policy on the extent of Government  interest  in real property within
these zones which may be retained or acquired  to protect the  operational
capability of active military airfields (subject in each case  to the
availability of required authorizations and  appropriations).

B.  APPLICABILITY

    This Instruction applies to air installations of  the Military Depart-
ments located within the United States, its  territories,  trusts, and
possessions.

C.  CRITERIA

    1.  General.  The Air Installations Compatible Use Zone for  each
military air installation shall consist of (a) land areas upon which
certain uses may obstruct the airspace or  otherwise be hazardous to
aircraft operations, and (b) land areas which  are exposed to  the health,
safety or welfare hazards of aircraft operations.

    2.  Height of Obstructions.  The land  area and height standards
defined in AFM 86-8 (reference (a)), NavFac  P-272 (reference  (b)), and
P-80 (reference (c)),  and TM 5-803-4 (reference (d))  will be  used for
purposes of height restriction criteria.

-------
    3.  Accident Potential

        a.   General

            (1)  Areas immediately beyond the ends of runways and along
primary flight paths are subject to more aircraft accidents than other
areas.  For this reason, these areas should remain undeveloped, or if
developed should be only sparsely developed in order to limit, as much
as possible, the adverse effects of a possible aircraft accident.

            (2)  DoD fixed wing runways are separated into two types for
the purpose of defining accident potential areas.  Class A runways are
those restricted to light aircraft (see enclosure 2) and which do not
have the potential for development for heavy or high performance aircraft
use or for which no foreseeable requirements for such use exists.
Typically these runways have less than 10% of their operations involving
Class B aircraft (enclosure 2) and are less than 8000 feet long.  Class
B runways are all other fixed wing runways.

            (3)  The following descriptions of Accident Potential Zones
are guidelines only.  Their strict application would result in increasing
the safety of the general public but would not provide complete protec-
tion against the effects of aircraft accidents.  Such a degree of protec-
tion is probably impossible to achieve.  Local situations may differ
significantly from the assumptions and data upon which these guidelines
are based and require individual study.  Where it is desirable to restrict
the density of development of an area, it is not usually possible to
state that one density is safe and another is not.  Safety is a relative
term and the objective should be the realization of the greatest degree
of safety that can be reasonably attained.

        b.   Accident Potential and Clear Zones (See Enclosure 3)

            (1)  The area immediately beyond the end of a runway is the
"Clear Zone," an area which possesses a high potential for accidents,
and has traditionally been acquired by the Government in fee and kept
clear of obstuctions to flight.

            (2)  Accident Potential Zone I (APZ I) is the area beyond
the clear zone which possesses a significant potential for accidents,

            (3)  Accident Potential Zone II (APZ II) is an area beyond
APZ I having a measurable potential for accidents.

            (4)  Modifications to APZs I and II will be considered If:

                 (a)  The runway is infrequently used.

                 (b)  The prevailing wind conditions are such that a
large percentage (i.e., over 80 percent) of the operations are in one
direction.

-------
                                                                A165.57
                                                               Nov 8, 77


                 (c)  Most aircraft do not overfly the APZs  as  defined
herein during normal flight operations (modifications may be made  to
alter these zones and adjust them to conform to the line of  flight).

                 j(d)  Local accident history indicates consideration  of
different area.

                 (e)  Other unusual conditions exist.

            (5)  The takeoff safety zone for VFR rotary-wing facilities
will be used for the clear zone; the remainder of the approach-departure
zone will be used as APZ I.

            (6)  Land use compatibility with clear zones and APZs  is
shown in enclosure 4.

    4.  Noise

        a.  Generaj..  Noise exposure is described in various ways.  In
1964, the Department of Defense began using the Composite Noise Rating
(CNR) system to describe aircraft noise.  Several years ago the Noise
Exposure Forecast (NEF) system began to replace CNR.  In August 1974,
the Environmental Protection Agency notified all Federal agencies  of
intent to implement the Day-Night Average Sound Level (Ldn) noise
descriptor, and this was subsequently adopted by the DoD.  This Ldn
system will be used for air installations.  Where AICUZ studies have
been published using the CNR of NEF systems or where studies have  pro-
gressed to the point that a change in the descriptor system is imprac-
tical or uneconomical, such studies may be published and continued in
use.  However, in such cases, data necessary for conversion to Ldn
should be collected and studies should be revised as soon as time  and
budgetary considerations permit.  However, if state or local laws  require
some other noise descriptor, it may be used in lieu of Ldn.

        b.  Noise Zones

            (1)  As a minimum, contours for Ldn 65, 70, 75 and SO shall
be plotted on maps as part of AICUZ studies.

            (2)  See section G. for a further discussion of Ldn use and
conversion to Ldn from previously used systems.,

D.  POLICY

    1.  General.  As a first priority step, all reasonable, economical
and practical measures will be taken to reduce and/or control the
generation of noise from flying and flying related activities.  Typical
measures normally include siting of engine test and runup facilities  in.
remote areas if practical, provision of sound suppression equipment
where necessary, and may include additional measures such as adjustment

-------
of traffic patterns to avoid built-up areas where such can be accomplished
with safety and without significant impairment of operational effective-
ness.  After all reasonable noise source control measures have been
taken, there will usually remain significant land areas wherein the
total noise exposure is such as to be incompatible with certain uses.

    2.  Compatible Use Land

        a.  General

            (1)  DoD policy is to work toward achieving compatibility
between air installations and neighboring civilian communities by means
of a compatible land use planning and control process conducted by the
local community.

            (2)  Land use compatibility guidelines will be specified for
each Clear Zone, Accident Potential Zone, Noise Zone and combination of
these as appropriate.

            (3)  The method of control and regulation of land usage
within each zone will vary according to local conditions.   In all
instances the primary objective will be to identify planning areas and
reasonable land use guidelines which will be recommended to appropriate
agencies who are in control of the planning functions for the affected
areas.

        b.  Property Rights Acquisition

            (1)  General.   While noise generated by aircraft at military
air installations should be an integral element of land use compatibility
efforts, the acquisition of property rights on the basis of noise by the
Department of Defense may not be in the long term best interests of the
United States.   Therefore, while the complete requirement for individual
installations should be defined prior to any programming actions, ac-
quisition of interests should be programmed in accordance with the
following priorities.

            (2)  Priorities

                 (a)  The first priority is the acquisition in fee
and/or appropriate restrictive easements of lands within the clear zones
whenever practicable.

                 (b)  Outside the clear zone, program for the acquisition
of interests first in Accident Potential Zones and secondly in high
noise areas only when all possibilities of achieving compatible use
zoning, or similar protection, have been exhausted and the operational
integrity of the air installation in manifestly threatened.  If program-
ming actions are considered necessary, complete records of all dis-
cussions, negotiations, testimony, etc., with or before all local

-------
                                                                4165.57
                                                               Nov 8, 77


 officials, boards, etc., must be maintained.  This will ensure that
 documentation  is available to indicate that all reasonable and prudent
 efforts were made to preclude incompatible land use through cooperation
 with  local government officials and that all -recourse to such action has
 been  exhausted.  Such records shall accompany programming actions and/or
 apportionment  requests for items programmed prior to the date of this
 Instruction.   In addition, a complete economic analysis and assessment
 of  the future  of the installation must be included.

                       (i)  Costs of establishing and maintaining com-
 patible use zones must be weighed against other available options, such
 as  changing the installation's mission and relocating the flying acti-
 vities, closing the installation, or such other courses of action as may
 be  available.  In performing analyses of this type, exceptional care
 must  be exercised to assure that a decision to change or relocate a
 mission is fully justified and that all aspects of the situation have
 been  thoroughly considered.

                      (ii)  When, as a result of such analysis, it is
 determined that relocation or abandonment of a mission will be required,
 then  no new construction shall be undertaken in support of such activ-
 ities except as is absolutely necessary to maintain safety and opera-
 tional readiness pending accomplishment of the changes required.

            (3)  Guidelines.  This Instruction shall not be used as sole
 justification  for either the acquisition or the retention of owned in-
 terests beyond the minimum required to protect the Government.

                 (a)  Necessary rights to land within the defined com-
 patible use area may be obtained by purchase, exchange, or donation, in
 accordance with all applicable laws and regulations.

                 (b)  If fee title is currently held or subsequently
 acquired in an area where compatible uses could be developed and no
 requirement for a fee interest in the land exists except to prevent
 incompatible use, disposal actions shall normally be instituted.  Only
 those rights and interests necessary to establish and maintain compatible
 uses  shall be  retained.  Where proceeds from disposal would be inconse-
 quential, consideration may be given to retaining title.

                 (c)  If the cost of acquiring a required interest
 approaches closely the cost of fee title, consideration shall be given
 to whether acquisition of fee title would be to the advantage of the
 Government.

    3.  Rights and Interests Which May Be Obtained.  When it is deter-
mined to be necessary for the Federal Government to acquire interests in
 land, a careful assessment of the type of interest to be acquired is
mandatory.   Section F.  of this Instruction contains a listing of possible
interests which should be examined for applicability.

-------
    4.  Environmental Impact Statements

        a.  Any actions taken with respect to safety of flight,  accident
hazard, or noise which involve acquisition of interests in land  must be
examined to determine the necessity of preparing an environmental impact
statement in accordance with DoD Directive 6050.1, "Environmental Con-
siderations in DoD Actions," March 19, 1974 (reference (e)).

        b.  All such environmental impact statements must be forwarded
to appropriate Federal and local agencies for review in accordance with
reference (e).

        c.  Coordination with local agencies will be in accordance with
OMB Circular A-95 (reference (f)).

E.  THE AIR INSTALLATION COMPATIBLE USE PROGRAM

    1.  The Secretaries of the Military Departments will develop, im-
plement and maintain a program to investigate and study all air  instal-
lations in necessary order of priority to develop an Air Installation
Compatible Use Zone  (AICUZ) program for each air installation consistent
with  Section D.  AICUZ studies which  contain an analysis of land use
compatibility problems and potential  solutions shall be developed and
updated as necessary.  As a minimum,  each Study shall include the
following:

        a.  Determination by detailed study of flight operations, actual
noise and safety surveys if necessary, and best available projections of
future flying activities, desirable restrictions on land use due to
noise characteristics  and safety  of flight;

        b.  Identification  of present incompatible  land uses;

        c.  Identification  of land  that  if inappropriately developed
would be  incompatible;

        d.  Indication of  types  of  desirable  development  for various
land  tracts;

        e.  Land  value estimates  for  the zones  in question.

         f.  Review of the  airfield  master plans  to ensure that  existing
and  future  facilities siting is  consistent with  the policies in this
Instruction.

         g.  Full  consideration of joint use  of  air installations by
activities  of separate Military Departments  whenever such use will
 result in maintaining operational capabilities  while reducing noise,
 real estate and construction requirements.

                                                               4165.57
                                                              Nov  8,  77


        h.  Recommendations for work with local zoning boards, necessary
minimum programs of acquisition, relocations,  or such other actions  as
are indicated by the results of the Study.

    2.  Procedures.  In developing AICUZ Studies the Secretaries of
Military Departments shall:

        a.  Follow the review and comment procedures established under
OMB Circular A-95 (reference (f));

        b.  Ensure that appropriate environmental factors are considered;
and

        c.  Ensure that other local, State or Federal agencies engaged
in land use planning or land regulation for a particular area have an
opportunity to review and comment upon any proposed plan or significant
modification thereof.

    3.  Coordination with State and Local Governments.  Secretaries  of
the Military Departments shall develop procedures for coordinating AICUZ
Studies with the land use planning and regulatory agencies in the area.
Developing compatible land use plans may require working with local
governments, local planning commissions, special purpose districts,
regional planning agencies, state agencies, state legislatures, as well
as the other Federal agencies.  Technical assistance to local, regional,
and state agencies to assist them in developing their land use planning
and regulatory processes, to explain an AICUZ Study and its implications,
and generally to work toward compatible planning and development in the
vicinity of military air fields, should be provided.

    4.  Property Rights Acquisition.  The AICUZ Study shall serve as the
basis for new land acquisitions, property disposal, and other proposed
changes in Military Departments real property holdings in the vicinity
of military airfields where applicable.

    5.  Required Approvals.  Based on the results of the AICUZ Studies,
each Military Department will prepare recommendations for individual
installations AICUZ programs for approval as follows:

        a.  The Secretaries of the Military Departments or their designa-
ted representatives will review and approve the AICUZ Studies establish-
ing the individual air installation AICUZ program.

        b.  When relocation or abandonment of a mission or an instal-
lation is apparently required, the Secretaries of the Military Depart-
ments will submit the proposed plan for the installation, with appro-
priate recommendations, to the Secretary of Defense for approval.

        c.  A time-phased fiscal year plan for implementation of the
AICUZ program in priority order, consistent with budgetary considera-
tions, will be developed for approval by the Secretary of the Military

-------
Departments, or their designated representatives.  These plans will
serve as the basis for all AICUZ actions at the individual installations.

    6.  Coincident Actions.  The Secretaries of the Military Departments
will also take action to assure in accordance with section U.I. and D.2.
that:

        a.  As the first priority action in developing an AICUZ program,
full attention is given to safety and noise problems.

        b.  In all planning, acquisition and siting of noise generating
items, such as engine test stands, full advantage is taken of available
alleviating measures, such as  remote sites or sound suppression equipment.

        c.  The noise exposure of on-installation facilities personnel
are considered together with that off the installation.

        d.  There is development or continuation with renewed emphasis,
of programs to inform local governments, citizens groups, and the general
public of the requirements of  flying activities, the reasons therefore,
the efforts which may have been made or may be taken to reduce noise
exposure, and similar matters  which will promote and develop a public
awareness of the complexities  of air installation operations, the problems
associated  therewith, and  the  willingness of the Department of Defense  -
to take all measures possible  to alleviate undesirable external effects.

    7.  Responsibilities  for the acquisition, management and disposal of
real  property are defined  in DoD Directive 4165.6, "Real Property, Acqui-
sition, Management  and Disposal," December 22, 1976  (reference  (g)).

    8.  The Deputy  Assistant Secretary  of Defense  (Installations and
Housing) will examine  the  program  developed pursuant to  this Instruction,
and  from time to  time  review the progress  thereunder to  assure  conformance
with  policy.

F.   REAL ESTATE  INTERESTS TO BE  CONSIDERED FOR CLEAR ZONES  AND  ACCIDENT

-------
                                                               4165.57
                                                              Nov 8,  77


    2.   The right to regulate or prohibit  the  release  into  the  air  of
any substance which would impair the  visibility or otherwise  interfere
with the operations of aircraft, such as,  but  not limited to,  steam,
dust and smoke.

    3.   The right to regulate or prohibit  light emissions,  either direct
or indirect (reflective), which might interfere with pilot  vision.

    4.   The right to prohibit electrical emissions which would interfere
with aircraft and aircraft communications  systems or aircraft navigational
equipment.

    5.   The right to prohibit any use of the land which would unneces-
sarily attact birds or waterfowl, such as, but not limited  to, operation
or sanitary landfills, maintenance of feeding stations or the growing of
certain types of vegetation attractive to birds or waterfowl.

    6.   The right to prohibit and remove any buildings or other non-
frangible structures.

    7.   The right to top, cut to ground level, and to remove trees,

G.  AIR INSTALLATIONS COMPATIBLE USE ZONE NOISE DESCRIPTORS

    1.  Composite Noise Rating (CNR) and Noise Exposure Forecast (NEF)
values as previously required by Sections III., IV., and V. of DoD
Instruction 4165.57, "Air Installations Compatible Use Zones," July 30,
1973 (reference (j)) will no longer be used.

    2.  Where CNR 100 (or the quietest boundary of CNR Zone 2 if other-
wise computed) or NEF 30 would previously have been used, data shall be
collected sufficient to permit computation of Ldn 65 noise contours and
these noise contours shall be plotted on maps accompanying AICUZ studies.

    3.  Where CNR 115 (or the boundary of CNR Zone 3 if otherwise com-
puted) or NEF 40 would previously have been used, data shall be collected
sufficient to permit computation of Ldn 75 noise contours and these
noise contours shall be plotted on maps accompanying AICUZ studies.

    4.  Where previous studies have used CNR or NEF, for matters of
policy, noise planning and decisiorunaking, areas quieter than Ldn 65
shall be considered approximately equivalent to the previously used CNR
Zone 1 and to areas quieter than NKF 30.  The area between Ldn 65 and
Ldn 75 shall be considered approximately equivalent to the previously
used CNR Zone 2 and to the area between NEF 30 and 40.  The area of
higher than Ldn 75 shall be considered approximately euqivalent to the
previously used CNR Zone 3 and to noise higher than NEF 40.  The proce-
dures shall remain in effect only until sufficient data to compute Ldn
values can be obtained.

    5.  When computing helicopter noise levels using data  collected  from
meters, a correction of +7db shall be added to meter readings obtained
under conditions where blade slap was present until and unless meters
are developed which more accurately reflect true conditions.

    6.  Noise contours less than Ldn 65 or more than Ldn 80 need not be
plotted for AICUZ studies.

    7.  Since CNR noise levels are not normally directly convertible  to
Ldn values without introducing significant  error,  care  should be exer-
cised to assure that personnel do not revise previous studies by erro-
neously relabeling CNR contours to the approximately equivalent Ldn
values.

    8.  Where intermittent impulse noises are such as are associated
with bombing and gunnery ranges are of importance, such noises will be
measured using standard "C" weighting of the various frequencies  to
insure a description most representative of actual human response.

DEPUTY DIRECTOR OF CONSTRUCTION STANDARDS AND DESIGN

                       TO THE


     GENERAL AVIATION LAND USE PLANNING SEMINAR

                    OCTOBER 5, 1979
          THE DEPARTMENT OF DEFENSE POLICY

                         ON

       AIR INSTALLATIONS COMPATIBLE USE ZONES

-------
Ladies and Gentlemen
     I am very pleased to be here today to discuss the Department of
Defense policy for planning the use of land in the vicinity of airports.
This policy is set forth in DoD Instruction 4165.57, which is titled
Air Installations Compatible Use Zones or, for short, A1CUZ.  DoD
Directives and Instructions are similar to Military regulations and set
forth general policy and guidance on how that policy will be carried out.
The Military Departments develop detailed procedures under this guidance
as required to fit their different missions and requirements.
     When we do develop a policy such as this one which has a substantial
impact on the public, we cannot do it in isolation in the Pentagon - public
participation is mandatory.  We therefore prepared a draft  Environmental
Impact Statement on the proposal and sent it to about 150 State Offices,
Area Clearing Houses, and other Federal agencies.  As I recall, we received
around 50 comments in reply - most were detailed, thoughtful, and helpful.
We cannot satisfy all commentors, of course, but we made many substantial
changes in the original document as a result of these comments.
     The current AICUZ  Instruction dated November 8,  1977 was published in
the Federal Register for public comment before we adopted it.  Very few
comments (only two, in  fact) were received this time, probably because the
proposed revisions were not perceived as being major.   I  have several  hundred
copies of the document  here as  handouts, and  I hope you all  have  received
a copy.

-------
     The AICUZ concept was  proposed originally by the Air Force as a
concept called "GREENBELT".  Several air bases were experiencing en-
croachment  in the form of intensive development immediately outside
the base boundries.  Where  such development was residential, it was
almost immediately followed by complaints against the noise made by
the aircraft.  A common reaction of many people to such complaints was
"well you knew the airport was here when you bought the house didn't you?"
Such a reaction does not win friends and it is not really fair.  People
tend to buy houses on weekends when flying activities are at a minimum,
and it is a rare case when a potential homeowner can sleep-in a few
nights to see if his rest is disturbed by night time flying.  In any
case, some complaints escalated into suits, and it became clear that
something must be done to stop encroachment.
     A large modern military jet installation represents hundreds of
millions of dollars in investment in land and fixed facilities which, if
flying were curtailed or stopped, would have to be duplicated in another
area.  Even if an air base  is built in a remote area, the population of the
base and the jobs it creates immediately invite development to start and
the process could be repeated.
     Also, and aside from the general cost to the taxpayers of building a
new base, the economic impact of closing a major base can be enormous.
Jobs are lost, people uprooted, business declines.  The Department of Defense
is not insensitive to these impacts and we strive to avoid them or lessen
them wherever and whenever possible.  Therefore, it is usually in the
economic interests of the Department of Defense, the taxpayers in general
and the local areas in particular, that a base be protected so that it can
continue to operate over long periods.

-------
     As I said, the first proposal  was the Greenbelt concept,  wherein
the Government would buy a strip of land five miles long and  two  miles
wide centered on our major runways  and permit no uses of that  land
other than agriculture, parks or just letting the trees and grass grow.
In its favor, the Greenbelt concept was simple to apply, and  it would
have kept development far enough away from our runways that noise would  not
have been a problem, and the areas  of high aircraft accident  potential
would have been contained within the Government-owned land.
     However, it would have cost billions of dollars; it would have re-
moved hundreds of thousands of acres from local tax rolls; it would have
displaced tens of thousands of persons and businesses, and it would have
prevented the development of a tremendous amount of highly desirable de-
velopmental land.  But weren't we trying to prevent development?   In part,
yes.    But not all development is undesirable or incompatible with airfield
operation.  Most industrial activities are not sensitive to noise.  Many
sensitive activities can be carried out satisfactorily in high noise areas
if the buildings in which they are  located are adequately insulated.  Some
apparently compatible uses of land  in the high noise and accident potential
area, such as agriculture, or sanitary land fills, are not really compatible
since they can attract flocks of birds which are highly dangerous to air-
craft.
     Thus, it was obvious that what we needed to do was to identify those
uses  of land which are compatible with aircraft operations, and those which
are not.   Then a further refinement needed to be made to judge just how
incompatible certain uses are.   We  started with noise.

-------
     Fortunately, many  studies of the psychological impact of noise had
been made.  The Air  Force had been making such studies since, at least,
the early 1950s, the FAA, VA, HUD, and many other agencies and foreign
Governments had all  been studying aircraft noise.  The excellent FHA
Guide to Control of Airborne Impact and Structure Borne Noise in Multi-
Family Dwellings had been published in 1967, and the Joint Army-Navy-
Air Force Manual on Land Use Planning with Respect to Aircraft Noise in
1964.  Therefore, we did not have to reinvent the wheel to come up with
compatible land uses, only make it a little rounder.
     Our first policy concentrated on noise and was rather general with
respect to land uses that were compatible with high noise levels.  Ac-
quisition of land or restrictive easements on land was permitted although
we preferred local zoning action to control land use.
     I think I should emphasize at this point that our first policy, and
our policy today, requires that as a first step, we will take all reasonable,
economical, and practical measures to reduce or control noise from air-
craft.  These steps will include adjustment of traffic patterns, sound
suppression measures on ground facilities, and reduction of night time
activities, if practical.  However, airplanes will still make noise.
     When I said that acquisition of land was permitted, I should also
state that the Department of Defense does not want to buy land.  We do
not like to take land off local tax rolls, we do not like to spend
money on land instead of airplanes or tanks, we do not like to have to
manage land we don't need.  Further, we have to get authority from the
Congress and appropriations from the Congress in order to acquire land.
It is not something  that we can just do by ourselves.

-------
     It was in the early stages of the program when  we were  first
asking for the Congressional  approvals that we needed, that  the Congress
gave us some rather clear direction as to how the program should be
restructured for the years ahead.   The Congress stated that  the acquisi-
tion of land for noise reasons alone might not be in the best interest
of the United States, that even more emphasis should be placed on  local
zoning actions or other state and municipal actions  to control en-
croachment and that we should concentrate more on the potential of air-
craft accidents in the vicinity of airfields.
     As a result of this Congressional direction, studies of aircraft
accidents were undertaken and we determined that, for our major airfields,
we should increase the size of the clear zone at the end of runways.  That
is, that zone wherein no buildings or obstructions to flight are permitted.
It is a zone 3,000 feet long and 3,0000 feet wide centered on the runway
centerline.  Because almost nothing is permitted in this zone, the De-
partment of Defense will usually buy the land or a restrictive easement on
the land to assure that it does remain clear.
     Beyond the clear zone we have identified Accident Potential Zones I
and II.  These continue at 3,000 feet wide, APZ  I for 5,000  feet, and
APZ II for an additional 7,000 feet,  we identify APZ I as having a
significant potential for accidents and APZ II as having a measureable
potential for accidents.  Beyond these zones, the potential for accidents
is not significantly above that of the country as a whole.

-------
     We do not state that any specific probability exists that an
aircraft will have an accident in these zones in any given time period.
This could be calculated if aircraft and flying techniques remained
static, but they do not.  Both are constantly changing.  But these
zones do represent a reasonable delineation of the fact that accident
frequency decreases as distance from the runway increases.  The AICUZ
instruction lists in its Enclosure 4 those uses which we believe to be
compatible with the clear and accident-potential zones.  Since I hope you
all have copies, I will not repeat them all now.
     There is a portion of the AICUZ instruction which I believe is important
enough to read or paraphrase at this time, however.   This is the part
that deals with acquisition of land by the Department of Defense and is  a
direct outgrowth of the instructions we received from Congress.  It states
that the first priority for acquisition, either in fee simple or appropriate
restrictive easements will be the clear zone, the 3,000 x 3,000 foot zone
on the end of major runways.  At most of our air installations, we already
own all or a substantial portion of these areas.
     If it appears that we should acquire some interest in land beyond the
clear zones, action to program for such acquisition may be taken - for
accident-potential zones first, and for high noise areas second - only when
all possibilities of achieving compatible use zoning or similar protection
have been exhausted, and the operational integrity of the base is manifestly
threatened.

-------
      If procurement actions are considered necessary,  complete records
 of all discussions, negotiations, testimony, etc.,  with or before all
 local officials, boards, etc., must be maintained.   This will  ensure
 that documentation is available to indicate that all reasonable and
 prudent efforts were made to preclude incompatible  land use through
 cooperation with local government officials, and that all recourse to
 such action has been exhausted.  By this policy, we do run the risk
 that development and encroachment may progress so far that we  are unable
 to effectively stop or change it.  However, we believe so strongly that
 land use decisions should be made by an informed public and its local
 representatives, rather than by the Federal Government, that we are willing
 to accept that risk.
      I referred to an informed public.  We recognize that it is our responsi-
 bility to inform.   This is a very important part of our AICUZ  policy.   We
            t
 require that the Military Departments develop procedures for  coordinating
 AICUZ studies with the land use planning and regulatory agencies in the af-
 fected area.   They will work with local governments, planning  agencies,
 state agencies, and legislators, and provide technical assistance to them
 to aid in developing their land use planning and regulatory processes,  to
 explain the implications of an AICUZ study and generally work  toward
compatible planning and development in the vicinity  of air installations.
      The Military  Departments must have programs to inform local governments3
 citizens groups, and the general public of our requirements for flying  ac-
 tivities and  the reasons for them, what we have done and can do to reduce
 noise and hazards, and to generally promote an awareness of what we are
 doing and our willingness to work with them.  Through such mutual under-
 standing, we  hope  to achieve a cooperation that will benefit both us and
                                  7

-------
the local community.   In  this  line, the Air  Force has elected to publish
its AICUZ studies  in  the  form  of reports to  the people in the area of the
installation  being  studied.  Complete  information is thereby made available
to the people, and  they can base their planning on facts.
     While  I  said we  will  provide technical  assistance, the Department
of Defense  does not provide any funding of local planning processes.  We
do not have Congressional  authorization to fund this type of activity,
although several other Federal agencies do.  By technical assistance, we
mean providing information and making our planners and other professionals
available to  the extent we can to explain and to advise and assist if
requested.
    Does the  system work? Do  we get the kind of local planning and control
we would like to  see? Sometimes, but  not always.  A few examples may serve
as illustrations.
     As of  the date I am  writing this, the Air Force has completed and
published 73  AICUZ  studies.  Twenty-five jurisdications have included the
AICUZ studies in  their comprehensive land use planning process and in their
plans.  Two areas  have fully incorporated the AICUZ recommendations in
their zoning  regulations.  Thirty-three areas have incorporated parts of
the AICUZ recommendations  in their zoning plans,  In ten areas, requests
for zoning  changes  or building permits that  would have resulted in in-
compatible  uses have  been  denied, two state  legislatures have enacted
enabling legislation  to permit zoning based  on AICUZ where such authority
was previously not  available.  Arizona has passed legislation that allows
                                   8

-------
for zoning for AICUZ, allows local governments to acquire land to assure
compatible uses, and permits state-owned land to be traded for other land
in compatible use zones as a method of acquisition.  Acquisition of land
and interests in land by local governments has occurred at two bases,
most notably Hill Air Force Base in Ogden, Utah where the State Legislature
appropriated funds to acquire compatible use zones.
      On the Navy side, Jacksonville, Florida enacted zoning regulations
that include compatible use zones for the three Naval Air Stations in the
area (Jacksonville, Mayport, and Cecil Field), and Jacksonville Airport,
the local commercial airport.
      In Patuxent River, Maryland, Air Installations Compatible Use Zones
were included ir the local zoning laws, and some planned uses that would have
been incompatible have been stopped.  Here is an example, however, that does
show that zoning is not the solution to all of our problems since it has
been held that certain land uses permitted prior to the revised zoning
are still permitted - in effect, a Grandfather Clause.
      There are many areas where we have not been successful.  One of these
is the Navy's complex of airfields in the Norfolk, Va. area.  Encroachment
there is so extensive that the only viable solution seems to be to purchase
properties.   Overall, however, I think that the record shows that the ap-
proach we have been using can work and has worked in many cases.
      Therefore, we do not plan any significant changes in our policy in the
immediate future.  We believe that by fully informing the public of what we
are doing,  what we must do, and what the impacts of these actions are, we  will
stimulate informed, reasonable, and correct responses on the part of that
public and  their elected officials.

-------
       In some cases, where  the viability of an air installation is in
danger and where the Congress agrees that acquisition actions are appro-
priate to alleviate the condition, we will buy land or restrictive ease-
ments on land to assure compatible use.  However, it must be understood
that the Department of Defense, indeed the Federal Government as a whole,
does not have one dollar to spend on such acquisitions that does not come
from the taxpayers of this  country, from you and me.  Therefore, action
by local governments to make good land use plans, to zone for compatible
uses, will save you and me  money.  Further, properly done, it can make
money by promoting the development of land to higher though  compatible
uses while preserving and enhancing the economic value of airfields,
military, commercial and general.
      For these reasons, I  was particularly pleased to be invited here
today, and you have my sincerest wishes for a successful seminar and
successful planning in the  future.

                            THANK YOU

                         WESTCHESTER EXPERIMENT
Ever since the aircraft ceased to be an interesting curiosity to those
on the ground, resident annoyance with noise has been the subject of
vigorous complaint.  For years, the owners, operators and users  of
airports and the Federal Government failed to deal with noise complaints
and looked at residents as irrational and unreasonable.  Residents on
the other hand took a conspiratorial view of noisemakers.

Blasted by noise which took away their peace and tranquility, and faced
with little or no response from the airport community, frustration set
in.

Thus, the scene was set for confrontation between two desperate  groups,
the airport and its neighbors, neither one fully understanding nor
trusting the other.

Westchester County (N.Y.) Airport (WCA) on the Connecticut border provided
a testing ground for the understanding and coalition of these two groups,
and for the development of noise abatement procedures with which both
groups were comfortable.  We call it the Westchester Experiment.

So that the Westchester Experiment may be used as a model for future
action, we will describe the background of the problem at WCA, the
governmental response to resident complaints and resident action in
precipitating the Experiment.

                        Background of the Problem

The Airport:

WCA is a 700 acre general aviation airport located on the Connecticut -
New York bolder.  Like many of the general aviation facilities,  it was
created from a little used World War II military installation that had
been located, during an emergency situation, into the midst of four
well-established residential communities.

During 1976, the airport ranked fourth in total operations and second
in general aviation operations in New York State.

The user group at WCA is mixed.  It includes the corporate jets  for many
of "Fortune's 500" corporations, light aircraft for private use  and for
training, and commercial carriers providing scheduled service.  Also,
the Air National Guard has an air reconnaissance mission at WCA.

-------
Each of the uses presented a different noise  experience  for  the  neigh-
bors and precluded any simple solution to the noise  problem.

Neighborhood Area:

The surrounding residential neighborhoods are as mixed as  the  aircraft
at WCA.  On the Connecticut side of the state line,  there  is a signif-
icant area of large lot development (2 to 4+  acres)  with expensive
homes.  On the New York side, land use patterns vary by  community  but
tend to be more dense.  Lot sizes there are generally one  acre or  less.
All of the communities have the usual combination  of schools,  churches,
hospitals and recreational areas.  There never was,  nor  is there now,
any significant business development in the area.

The Noise:

Early in the seventies, when annual operations were  at an  all  time high
of 282,000 movements, there were four types of objectionable airpdrt
noise.  Though there were other noise problems, these four were  the
subject of most neighborhood objection:  1) Jet operations,  particularly
during sleep hours from 10:UO p.m. to 7:00 a.m.; 2)  High frequencv jet
engine run-ups; 3) Use of reverse thrust, especially at  night; and, 4)
The daisy-chain of light aircraft doing touch and  go.

               Resident Complaints and Governmental  Action

Concerted resident complaints began in 1968.   Prior  to that  time they
had been sporadic.  The complaints were spurred by the growth  of WCA
from 145,000 operations in 1958 to 254,000 operations in 1968.  Further-
more, multiple uses of the airport and the increased use of  jets with no
discernible noise abatement procedures drove  residents to  bitter complaint,

Greenwich, Connecticut, residents through their Homeowner  Association
formally complained about aircraft noise from 1968 to 1974.  Their
complaints were constant and articulate.  They were  made orally  and in
writing.  They were addressed to every level  of government from  the FAA,
Eastern Region, to the owner of the airport,  Westchester County, New
York.  Residents enlisted and received the assistance of the Town  of
Greenwich and of their Congressman but their  complaints  fell on  deaf
ears.  There was no meaningful response.  The FAA  denied all authority
over use of the airport; the owner claimed that the  operator had authority
under terms of the lease; and the operator insisted  that Federal law
vested the authority in the FAA and owner respectively.   Thus, the
residents were carefully shuttled from one authority to  another  in what
might properly be called The Shell Game.

                             Citizen Action

In the spring of 1974 in total frustration over governmental deafness,
the residents of northwest Greenwich hired the Westport,  Connecticut,  law
firm of Davidson and Spirer to file a lawsuit.

Late in the summer of 1974, an action was filed in the Federal District
Court in New Haven, Connecticut, (Docket B-74-280) by the Homeowner
Association* against the owner and the operator of Westchester County
Airport and the FAA.  The citizens were Joined in this action by the
Town of Greenwich, Connecticut.  Essentially the plaintiffs' sought
$20,000,000 in damages, in addition to injunctive relief  requiring an
enforced noise abatement program and a curfew.  Finally,  the residents
had the- ear of Government!

In the six months following, considerable legal maneuvering took place.
The important result was that in January of 1975 the airport owner,
VestchfSter County, offered to negotiate, and the National Business
Aircraft Association (NBAA) sought to participate in the  negotiations
on behalf of their corporate members.

To offer to negotiate was immediately rejected by the Homeowner
Association for three reasons:

     1)   mistrust of the airport owner's motives, based  on years
          of experience;

     2)   realization that unstructured negotiations were worthless;
          and,

     3)   fear that prolonged negotiations would empty the Association's
          treasury because of increased legal costs.

Homeowner reluctance to negotiate was eventually overcome by the NBAA
and the l.estchester County Pilots Association.  l\'ith pernission of
counsel, the presidents of each of these organizations contacted the
president of the Homeowner Association.  A meeting was set up during
which these representatives of the aviation community convinced home-
owners of their sincerity and eagerness to deal with the  noise problem
by developing a noise abatement policy for WCA.  They also conveyed the
concern of both the airport owner and the Tcderal Government that a
peaceful solution to the problem be reached.

With NBAA assurances of technical assistance and some tough negotiating
between lawyers, a Stipulation of Settlement was hammered out and signed
in July of 1975, one year after the lawsuit was filed.  Determination  by
the homeowners to deal with their noise problem through the courts
finally produced the long awaited result.

                             The  Stipulation

The Stipulation is a comprehensive  document  that  sets  forth  the  parties,
their relationships and the conditions  governing  the negotiations  to
resolve the noise problem.   In  effect,  it  identifies the  users - the
people making the noise,  and the  residents -  the  people hearing  the
noise, as the principals  in these negotiations.

The Stipulation called for  the  formation of a Committee consisting of
these two groups to meet  on a regular basis with  a  specified agenda  (See
Appendix).  The Stipulation mandates  that  the FAA,  the airport owner,
and the operator serve the  Committee  in an advisory capacity, supplying
such data as needed to deal with  the  noise problem  objectively.

In recognition of what is now acknowledged as the airport owner's
responsibility, Westchester County  agreed  to  review, give good  faith
consideration and act upon  all  recommendations of the  Committee  with
respect to noise abatement  and  safety procedures.

Negotiations under the Stipulation  began in  September  1975 and have
continued productively to date.

                             Results  to Date

The Westchester Experiment  has  produced meaningful  results in terms  of
noise reduction.  Negotiations  under  the Stipulation and  concessions  by
the airport community have  resulted in  the following:

     1.   The development,  printing and distribution of a noise  abate-
          ment procedure  for WCA.  The  procedure  itself  is the  result of
          careful, expensive study  and  field  testing by the NBAA using
          aircraft borrowed from  the  corporations.  The procedure  docu-
          ment is designed  to be  inserted  in  the  pilot's  manual  and  is
          given to all users of the airport.   Work  is  under way  to have
          Jeppeson, pilot's manuals,  include  the  procedure in its
          regular publication.

     2.   A voluntary curfew of jet takeoffs  from 11:00 p.m. to  6:30
          a.m.  This curfew has been  adhered  to by  the majority  of
          resident users.  It has considerably reduced regional  noise
          but homeowners  feel that  there  is  still room for improvement. •

     3.   Elimination of  reverse  thrusts except in  an  emergency  situation.

     4.   A voluntary reduction in  touch and  go operations by using
          smaller regional  airports.
                                   -A-

-------
     5.    Prohibition of turbine engine run-ups  unless an emergency
          exists in which case approval must  be  given by the airport
          operator.  At all  times specified areas  of the airport are
          mandated for this  engine work.

     6.    A manned, twenty-four hour noise complaint number set up by
          the operator with  an established procedure for logging and
          dealing with each  complaint.

     7.    The purchase of a  portable noise monitoring unit  to measure
          noise exposure around the residential  community.  Funds are
          now being requested for a permanent monitoring system to
          insure a constant  noise measurement nearer the source.

     8.    Installation, by the owner, of instrument  guidance  systems  to
          assist in compliance with noise abatement  and safety procedures
          ngreed upon nt WCA.

     9.    Nationwide publication that WCA is  a noise sensitive airport
          and that noise abatement procedures are  in effect and must  be
          obeyed by al] pilots.

    10.    Representation of  homeowners on the WCA  Master Plan Policy
          Liaison Board.  The Board will provide the citizen-resident
          input for development of n long range plan  for WCA.

These results were not easily achieved.  The  first few meetings were
tense and nt times alir.est hostile.  The hostility  stemmed  from  the  home-
owners lont, frustration nnd  anger, and the pilots' anxiety  over  the
demands that might be made on them.

In retrospect, we realize that these sessions served a  constructive
purpose; the^J enabled all parties to air their resentments,  and  realize
that the problems involved were not, after all, insurmountable.

While there are many difficult issues still to be  resolved, the  dialogue
between the airport community and the homeowners has produced objective
discussion, mutual trust and an atmosphere of positive  solution.   The
work to d.itc hns gone a long way towards making Westchester County Airport
a better neighbor.  Future discussions and action hopefully will  make it
a good neighbor, so that any future resort to the Courts will be unnecessary,

Through our experience with  the Westchester Experiment  we have found
that reasonable people, working together, can achieve a great deal.

   "A STATE PERSPECTIVE ON GENERAL AVIATION AND PLANNING"

         AN ADDRESS PRESENTED AT THE EPA CONFERENCE
ON GENERAL AVIATION AIRPORT NOISE AND LAND USE COMPATIBILITY
                     OCTOBER 3-5, 1979
           BY LLJCIE G, SEARLE, COMMUNITY LIAISON
             MASSACHUSETTS AERONAUTICS COMMISSION

     I AM DELIGHTED TO BE A PARTICIPANT IN THIS EPA CONFERENCE ON
GENERAL AVIATION AIRPORT NOISE AND LAND USE PLANNING,  IT'S A SUBJECT
THAT'S CLOSE TO OUR HEARTS AND EARS IN MASSACHUSETTS, so I WELCOME
THIS OPPORTUNITY TO SHARE WITH YOU SOME OF OUR THOUGHTS ON THE SUBJECT
WHICH ARE, OF COURSE, FROM ONE STATE'S PERSPECTIVE,
     RECENTLY, I STUMBLED ACROSS A MAGAZINE ARTICLE THAT I BELIEVE
SUMS UP QUITE NICELY THE AVIATION NOISE PROBLEM FROM THE PERSEPCTIVE
OF AN AIRPORT NEIGHBOR,  IT IS ENTITLED "AIRPLANE, STAY 'llAY FROM MY
ROOF,'"'  THE AUTHOR WRITES:  "You MOVE OUT FROM THE NOISE OF A CITY,
YOU PAY A PREMIUM TO BE AWAY FROM THE RAILROAD, YOU GO TO A LOT OF
TROUBLE AND EXPENSE TO GET ON A SIDE STREET AWAY FROM BUSSES AND THE
TRUCKS,  SO WHAT DO YOU GET?  WHY, ALONG WITH A BIG MORTGAGE, NEIGHBORS,
A MANGY LAWN AND A LEAKING BASEMENT, YOU GET PLANES,  IT TURNS OUT
YOUR QUIET RESIDENTIAL SECTION IS A BOARDWALK FOR MODERN AVIATION,
AND THE PLANES COME OVER AS IF YOU HAD PUT SUET OUT FOR THEM,"  THIS
ARTICLE APPEARED IN A 1947 ISSUE OF THE SATURDAY EVENING POST!  IT
WAS CITED AT AN EARLIER AVIATION CONFERENCE SPONSORED BY THE NATIONAL
AERONAUTIC ASSOCIATION IN 1947 AND USED IN A SPEECH ENTITLED ''MAKING
GOOD NEIGHBORS OF AIRPORTS,"
     TODAY IN HASSACHUSETTS, WE HAVE A GENERAL AVIATION NOISE PROBLEM
THAT IMPACTS NOT ONLY AIRPORT NEIGHBORS LIKE THE AUTHOR OF THIS ARTICLE,

-------
                               2
BUT THREATENS THE VIABILITY OF SEVERAL OF OUR KEY  SUBURBAN  GA AIRPORTS,
BECAUSE OF NOISE, WE ARE HAVING GREAT DIFFICULTY—IN FACT,  WE ARE
LOSING THE BATTLE AT ONE PARTICULAR AIRPORT—IN MAINTAINING THE  RUN-
WAYS AND TAX IWAYS THAT WE ALREADY HAVE, NEVER MIND EXTENDING OR
ADDING NEW RUNWAYS,  A.ND IF YOU REALLY WANT TO HAVE A SHOWDOWN
BETWEEN THE AIRPORT AND ITS NEIGHBORS, TRY TO PUT  IN AN INSTRUMENT
LANDING SYSTEM,  ALTHOUGH SUCH A KEY NAVIGATIONAL  AID, UNDOUBTEDLY,
ENHANCES SAFETY FOR AIRPORT NEIGHBORS AND USERS, IT IS REGARDED—
IRRATIONALLY,  I BELIEVE— BY MANY AS A PIECE OF EQUIPMENT THAT WILL
LEAD TO AN INCREASE IN OPERATIONS AND, THEREFORE,  MORE NOISE.  WHAT
MAKES TODAY'S  SITUATION so AGONIZING is THAT JUST  ABOUT ALL OF
OUR GENERAL AVIATION AIRPORTS IN MASSACHUSETTS WERE SITED 30-40 YEARS
AGO IN UNDEVELOPED AREAS SURROUNDED BY AMPLE OPEN  SPACE,
     THE SOLUTIONS TO OUR NOISL PROBLEM TODAY ARE  THE SAME ONES THAT
WERE AVAILABLE IN 1947:  NOISE CONTROL AT THE SOURCE THROUGH QUIETER
AIRCRAFT,1 OPERATING PROCEDURES; AND LAND USE CONTROLS,  FROM THE
STATE PERSPECTIVE, I'M GOING TO REVIEW EACH OF THESE THREE ELEMENTS
AND COMMENT ON OUR EXPERIENCE AS WELL AS WHAT  I BELIEVE NEEDS TO BE
DONE,  OUR ''MASSACHUSETTS EXPERIENCE'''  INVOLVES A STATE SYSTEM OF
25 PUBLICLY OWNED AIRPORTS AND AS MANY PRIVATELY OWNED AIRPORTS OPEN
TO THE PUBLIC,
1,   SOURCE CONTROL is PRIMARILY A FEDERAL AND  INDUSTRY RESPONSIBILITY,
     FROM A STATE VIEWPOINT, WE BELIEVE A GREAT DEAL  REMAINS TO BE
     DONE HERE, PARTICULARLY WITH PISTON ENGINED PROPELLER AIRPLANES,
     PROPS ARE BY FAR THE BIGGEST USERS OF OUR GENERAL AVIATION
     AIRPORTS,  BESIDES THEIR HIGH VISIBILITY  AND,  I  MIGHT ADD,
     AUDIBILITY, IN THE TOUCH AND GO OPERATIONS ASSOCIATED WITH FLIGHT
     TRAINING, PROPS CONSTITUTE THE LARGEST SEGMENT OF THE BUSINESS
     AVIATION  FLEET, WHICH MAKES EXTENSIVE USE OF OUR GA AIRPORTS,

-------
                               3
     PROP NOISE CAN BE CONTROLLED BY REDUCING PROPELLER TIP SPEED
WHICH CAN BE ACHIEVED BY A SLOWER TURNING PROP OR A MULTI-BLADED
PROP,  FROM WHAT I CAN LEARN, WE ALREADY HAVE A GOOD DEAL OF KNOW-
HOW WHICH GOES BACK MANY YEARS,  AND ADDITIONAL RESEARCH IS GOING
ON RIGHT NOW TO LEARN HOW TO BUILD A LOW-NOISE PROP—SUITABLE FOR
NEW DESIGN AIRPLANES OR RETROFIT—WITHOUT SACRIFICING PERFORMANCE,
THIS EFFORT IS BEING CONDUCTED JOINTLY BY MIT AND NASA UNDER EPA
SPONSORSHIP,
     WHAT SEEMS TO BE MISSING  is THE INCENTIVE,, PARTLY BECAUSE IT
IS' ONLY IN RECENT YEARS THAT GENERAL AVIATION AIRPORT NEIGHBORS
HAVE FLEXED THEIR POLITICAL MUSCLES AND PARTLY BECAUSE FAA's FAR 36
STANDARDS FOR LIGHT PROPS PRESENT LITTLE OR NO CHALLENGE TO THE
INDUSTRY,  SINCE FAR 36 WAS ESTABLISHED IN 1969, THE MODEST STANDARDS
SET FOR LIGHT PROPS (UNDER 12,4"QO LBS.) HAVE NOT BEEN AMENDED TO
REQUIRE MORE STRINGENT NOISE LEVELS,  THE RESULT IS THAT THE VAST
MAJORITY OF LIGHT PROPS HAVE, FOR SOME TIME,, MET FAA/S LENIENT
STANDARDS,
     FROM THE INDUSTRY'S POINT OF VIEW, ONE OBSTACLE MAY BE THE
ENORMOUS COST AND COMPLEXITY OF FAA CERTIFICATION OF EVEN THE
SLIGHTEST DESIGN CHANGE, A SITUATION WHICH OBVIOUSLY DISCOURAGES
INNOVATION AND RETROFIT,  I ALSO WANT TO ACKNOWLEDGE THAT SOME OF
THE NEWER MODEL PROPS—AND HERE I THINK OF THOSE MANUFACTURED BY
CESSNA AND PIPER—HAVE ACHIEVED COMMENDABLE NOISE REDUCTION GAINS, PRI-
MARILY BY LOWERING THE R.PMs,
     AT ANY RATE, A COMPELLING CASE CAN BE MADE FOR IMPROVING THE PROP
SITUATION, PARTICULARLY WHEN WE REMEMBER THAT THIS FLEET DOES NOT
TURN OVER VERY QUICKLY,  THERE IS A BACK DOOR APPROACH TO DEALING WITH
THE FEDERAL REGULATORY INERTIA WHICH MY OWN COMMISSION HAS REFUSED
TO SANCTION SO FAR, PARTLY BECAUSE OF THE CHAOS THAT WOULD RESULT

-------
FROM AIRPORT TO AIRPORT AND STATE TO STATE AND ALSO BECAUSE IT
WISHES TO AVOID REINFORCING WHAT SOME REGARD AS MASSACHUSETTS'
ANTI-BUSINESS IMAGE,   AND THAT IS THE SETTING OF MAXIMUM AIRCRAFT
NOISE LEVELS BY THE AlRPORT PROPRIETOR,   ONE OF OUR GA AIRPORTS
PROPOSED TO SET A NOISE LEVEL REQUIREMENT WHICH WOULD HAVE BEEN
MORE STRINGENT THAN FAR 36, BUT FOR SEVERAL REASONS, MY COMMISSION
TURNED THE PROPOSAL DOWN,  THE POINT I WANT TO MAKE HERE IS THIS:
WE WOULD LIKE TO TIE OUR STATEWIDE SOURCE NOISE POLICY TO A NATIONAL
NOISE STANDARD SUCH AS FAR 36j BUT IT BECOMES INCREASINGLY HARD TO
DO THIS BECAUSE SOME OF THE FAR 36 STANDARDS ARE SO WEAK,
     THE EFFORT TO QUIET THE BUSINESS JET FLEET IS ANOTHER STORY,
HERE, I BELIEVE, WE HAVE BEEN MUCH MORE SUCCESSFUL,  DESIGN STANDARDS,
FIRST SET BY THE FAA IN 1969, WERE TIGHTENED IN 1977, AND A PRODUCTION
CUTOFF DATE OF 1975 WAS SET FOR OLDER NOISY MODELS,  THERE IS HARDLY
AN AIRPORT NEIGHBOR THAT DOESN'T RECOGNIZE THE QUIETNESS OF THE CESSNA
CITATION,  THERE ARE OTHERS WITH IMPRESSIVE NOISE RECORDS, TOO, SUCH
AS THE FALCON 10, THE WESTWIND, AND THE NEWER LEAR JETS, JUST TO NAME
A FEW,  IN FACT, WE HAVE DOCUMENTED THAT AT ONE OF OUR GA AIRPORTS,
OVER Wo OF THE BUSINESS JET FLEET IS MADE UP OF CITATIONS AND
SIMILAR TURBO FANS,  WHILE I DO NOT HAVE COMPLETE FIGURES FOR OUR
OTHER GA AIRPORTS, IT WOULD NOT SURPRISE ME TO LEARN THAT A LARGE
PERCENTAGE OF THEIR BUSINESS JET FLEETS IS COMPOSED OF THE QUIETER
MODELS,  WHILE THE BUSINESS JET FLEET HAS A MUCH FASTER TURNOVER
THAN THE PROP FLEET,  THE FACT REMAINS THAT BOTH TECHNOLOGY AND
THE MARKETPLACE HAVE RESPONDED TO FAA'S INCREASINGLY STRINGENT FAR 36
STANDARDS,

-------
                               5
2,   OPERATING PROCEDURES is THE SECOND OF THE THREE PART SOLUTION,
     THIS INVOLVES DESIGNING SITE SPECIFIC MEASURES THAT ADDRESS AN
     AIRPORT'S PARTICULAR NOISE PROBLEMS,   IN MASSACHUSETTS,  THESE
     HAVE INCLUDED PRESCRIBED.FLIGHT PATHS, PREFERENTIAL RUNWAYS,
                      +*uck  1 f*
     REQUIREMENTS THAT AIRPLANES BE AIRBORNE IN THE FIRST HALF OF
                      A
     THE RUNWAY, TIME OF DAY  AND SEASONAL RESTRICTIONS FOR TOUCH
     AND GO OPERATIONS AND DESIGNATED AREAS FOR RUNUPS,
          WE HAVE FOUND THAT THE MOST EFFECTIVE RESULTS COME AFTER
     A PARTICIPATORY EFFORT THAT INVOLVES AIRPORT NEIGHBORS AND
     USERS ALONG WITH THE RESPONSIBLE FEDERAL, STATE AND LOCAL
     OFFICIALS,
          OPERATING PROCEDURES ARE NOT A PANACEA, BUT THEY CAN HELP
     TO MINIMIZE NOISE IMPACTS, PARTICULARLY IF SOME NON RESIDENTIAL
     AREAS STILL EXIST OVER WHICH AIRCRAFT CAN BE DIVERTED,  ALSO,
     OPERATING PROCEDURES OFTEN OFFER THE ONLY TANGIBLE NOISE RELIEF
     TO AIRPORT NEIGHBORS,
          WHEN I THINK ABOUT OPERATING PROCEDURES AT OUR GA AIRPORTS,
     I CANNOT HELP BUT SINGLE OUT THE NATIONAL BUSINESS AIRCRAFT
     ASSOCIATION WHICH HAS BEEN A LEADER  IN DEVISING PROCEDURES AND
     SPREADING THE NOISE ABATEMENT MESSAGE AMONG ITS MEMBERS,
          To GET THE MOST OUT OF PROCEDURES, IT HAS BEEN OUR
     EXPERIENCE THAT WE NEED MORE HELP FROM THE FAA AlR TRAFFIC CONTROL-
     LERS AT OUR TOWERED AIRPORTS,  WHILE WE DO NOT EXPECT THEM TO
     ENFORCE LOCAL REGULATIONS, WE BELIEVE MORE COULD  BE DONE TO
     INFORM AND REMIND PILOTS OF THE NOISE RULES IN EFFECT,
3,   LAND USE. THE THIRD ELEMENT OF OUR NOISE ABATEMENT TRIO,  is  A MOST
     CRITICAL AND CHALLENGING TASK,  APPLYING LAND  USE CONTROLS  IS,
     UNDOUBTEDLY, A LOCAL AND STATE RESPONSIBILITY, ALTHOUGH  THERE IS
     CERTAINLY A FEDERAL ROLE,  PARTICULARLY  IN THE  FINANCIAL  AREA,

-------
                         6
HERE ARE SOME OBSERVATIONS AND HIGHLIGHTS BASED ON OUR
EXPERIENCE,
     IN OUR STATE, AND I  SUSPECT THIS IS TRUE IN MANY OTHERS,
LAND USE IS A JEALOUSLY GUARDED LOCAL FUNCTION, IN LARGE PART
BECAUSE OF THE PROPERTY TAX IMPLICATIONS,  OUR ONE EFFORT, IN
1976, TO ENACT STATE LEGISLATION THAT WOULD HAVE REQUIRED LOCAL
GOVERNMENTS TO EXERCISE LAND USE CONTROLS NEAR AIRPORTS, WAS
UNSUCCESSFUL,  THE PROBLEM IS COMPOUNDED, OF COURSE, BY THE
NEED FOR PROPER LAND USE PLANNING, NOT ONLY ON THE PART OF THE
MUNICIPALITY IN WHICH THE AIRPORT IS LOCATED, BUT ALSO THE
ABUTTING COMMUNITIES,  OUR CLASSIC "WHAT NOT TO DO STORY" IS OF
ONE OF OUR MORE ACTIVE SUBURBAN BOSTON GA AIRPORTS, BUILT IN
THE 1940's,   BEVERLY AIRPORT is LOCATED  IN BEVERLY AND DANVERS
AND ABUTS A THIRD COMMUNITY, WENHAM,  FOR SOME TIME, THIS AIRPORT
WAS PRETTY MUCH SURROUNDED BY UNDEVELOPED LANDj BUT IN THE
EARLY 1960'S, A DEVELOPER PURCHASED SOME ADJACENT FARM
LAND IN THE NEIGHBORING TOWN OF DANVERS AND BUILT SCORES OF
HOMES, SOME OF WHICH ARE LESS THAN 400 FT, FROM THE LONGEST
RUNWAY,  TODAY, OF COURSE, IT is A NO WIN SITUATION FOR ALL
INVOLVED BECAUSE THE AIRPORT NEIGHBORS HAVE TO CONTEND WITH
NOISE,AND THE PILOTS HAVE HAD NOISE ABATEMENT RESTRICTIONS
IMPOSED ON THEM,
     WHAT ARE WE DOING ON THE STATE LEVEL TO PREVENT THIS KIND
OF  INCOMPATIBLE DEVELOPMENT FROM RECURRING?  BASICALLY, FOUR
THINGS:  (1) PROVIDING TECHNICAL ASSISTANCE; (2) PROMOTING
AIRPORTS AS ECONOMIC AND TRANSPORTATION  ASSETS,1  (3) JAWBONING
AND MORAL SUASION,1 AND (4) INVOLVING NEW RECRUITS  IN THE  CAUSE,
     ON THE FIRST:  PROVIDING TECHNICAL  ASSISTANCE  MEANS

-------
                          7
WORKING WITH AIRPORT MANAGEMENT AND LOCAL OFFICIALS  TO COME
UP WITH WAYS TO INSURE COMPATIBLE LAND USE,   THIS MAY INVOLVE
ZONING, PURCHASE OF LAND OR EASEMENTS, SUBDIVISION CONTROL,
NOTICE TO PROSPECTIVE RESIDENTS THAT AN AIRPORT IS NEARBY,  SPECIAL
PERMITS AND OTHER STRATEGIES,   BECAUSE THIS  IS HOW I SPEND A
GOOD DEAL OF MY TIME, I HAVE,  DURING THE PAST YEAR,  PUT TOGETHER
A GUIDE TO COMPATIBLE LAND USE PLANNING NEAR AIRPORTS IN
MASSACHUSETTS,  THIS is A SOUP TO NUTS COOKBOOK THAT PROVIDES
RECIPES FOR THESE AND OTHER LAND USE CONTROL METHODS,
     ON THE SECOND: REMINDING COMMUNITIES OF THE ECONOMIC
AND TRANSPORTATION VALUE OF THEIR AIRPORTS:   SOMEWHERE BETWEEN
THE EARLY DAYS OF AVIATION WHEN A MUNICIPALITY WAS WILLING TO
GIVE ITS EYE TEETH TO GET AN AIRPORT, AND TODAY'S NO GROWTH
AND ENVIRONMENTAL PHILOSOPHIES, MANY OF OUR CITIES AND TOWNS
HAVE FORGOTTEN OR LOST SIGHT OF THE VALUE OF THEIR AIRPORT,  I
AM CONVINCED THAT MY JOB OF PERSUADING A PLANNING BOARD THAT A
CERTAIN PARCEL OF LAND OUGHT TO BE REZONED TO PROHIBIT RESIDENTIAL
DEVELOPMENT WOULD NOT BE SO DIFFICULT  IF THE PLANNING BOARD
MEMBERS AND OTHER LOCAL OFFICIALS COULD SEE A DIRECT RELATION
BETWEEN THE NEED TO PROTECT THE AIRPORT ON ONE HAND, AND THE
ECONOMIC BENEFIT OF THE AIRPORT TO THEIR COMMUNITY, ON THE OTHER,
THIS CAN BE TOUGH BECAUSE  IT  IS NOT ALWAYS EASY TO QUANTIFY THE
VALUE OF OUR GA AIRPORTS,  MANY OF THEM JUST ABOUT BREAK EVEN,
SO THEY ARE NOT DIRECTLY ENRICHING THE LOCAL COFFERSj AND  A GOOD
DEAL OF TAX EXEMPT LAND IS INVOLVED,   WHAT WE'VE BEEN DOING  IS
POINTING TO AIRPORTS AS GENERATORS OF  JOBS BOTH ON AND OFF THE
AIRPORT; AND AS AIR TRANSPORTATION ASSETS THAT CAN HELP ATTRACT
INDUSTRY TO AN AREA,  BESIDES DOING THIS THROUGH  PAPERS, ARTICLES,

-------
                          8
AND TALKS, WE HAVE STRONGLY RECOMMENDED THAT AIRPORT MASTER
PLANS IDENTIFY AN AIRPORT'S PRESENT AND POTENTIAL ECONOMIC
ROLE,  IN ADDITION, WE'VE BEEN PUSHING AIRPORT INDUSTRIAL
PARKS AS AN EXTREMELY COMPATIBLE LAND USE,
     ON THE THIRD:  JAWBONING AND MORAL SUASION CAM BEST BE
ILLUSTRATED BY AN EXAMPLE,  ABOUT THREE YEARS AGO, THE ClTY OF
WORCESTER ANNOUNCED PLANS TO BUILD AN INDUSTRIAL PARK ON
AIRPORT PROPERTY AND LAND ADJACENT TO ITS AIRPORT, A PROJECT
WHICH WE APPLAUDED,  THE PLANS CALLED FOR A RATHER SOPHISTICATED
LIMITED ACCESS HIGHWAY TO BE BUILT TO THE AIRPORT,  SHORTLY
AFTER THE HIGHWAY PLAN SURFACED, AN ABUTTING LAND OWNER TOOK
STEPS TO GAIN SUBDIVISION APPROVAL FOR ALMOST 500 HOMES TO BE
BUILT ON A PARCEL OF LAND WHICH WOULD BECOME DEVELOPABLE ONCE
THE ROAD WAS COMPLETED,  SlNCE THE COMMONWEALTH OF MASSACHUSETTS
HAD NO LEGAL AUTHORITY TO PROHIBIT SUBDIVISION APPROVAL BY THE
CITY OF WORCESTER, WE APPLIED WHAT I CALL JAWBONING AND MORAL
SUASION,  FROM OUR DOT SECRETARY ON DOWN, WE POINTED OUT THE CITY'S
WOULD BE  INCONSISTENCY OF PROMOTING AN INDUSTRIAL PARK ON ONE
SIDE OF THE AIRPORT WHILE PERMITTING HOUSES ON THE OTHER,  LOCAL
PILOTS APPLIED PRESSURE; AND WE COMMENTED VIGOROUSLY THROUGH THE
A-95 REVIEW PROCESS,   I WAS FAIRLY NEW AT MY JOB, AND I WAS
DETERMINED NOT TO LET THIS SLIP THROUGH THE CRACKS,   IT JUST SO
HAPPENED THAT IN THE 1976 RENEWAL BY CONGRESS OF THE AlRPORT
DEVELOPMENT AID PROGRAM  (ADAP), ACQUISITION OF LAND OR  INTERESTS
THEREIN NEAR AN AIRPORT FOR NOISE COMPATIBILITY PURPOSES WAS
ADDED AS AN ITEM ELIGIBLE FOR UP TO 90% FEDERAL FUNDING.  WE
IMMEDIATELY PREPARED A GRANT APPLICATION FOR THE ClTY OF
WORCESTER TO ACQUIRE THE  PARCEL, AND  I ENTHUSIASTICALLY SUGGESTED
TO THE ClTY MOTHERS  (AND  FATHERS) THAT I THOUGHT WE COULD GET

-------
                          9
THE DESIRED FEDERAL FUNDING,   As IT  TURNED  OUT,  V-lORCESTER  DID
NOT GET ANY FEDERAL MONEY FOR REASONS WHICH I  WILL GO  INTO LATER,
THE UPSHOT OF OUR STATE JAWBONING WAS THAT  THE CITY—VERY  MUCH
TO ITS CREDIT—SPENT ABOUT $160,000  OF ITS  OWN MONEY TO BUY
ABOUT 130 ACRES,   I AM TOLD THAT THANKS TO  MY  POLLYANNA
PROMISES OF "OH,  I'M SURE WE CAN GET FEDERAL FUNDING FOR YOU,"
WORCESTER HAS UNOFFICIALLY NAMED THIS PARCEL THE Luc IE SEARLE
MEMORIAL PARK!
     ON THE FOURTH:  INVOLVING NEW RECRUITS IS MY WAY  OF SAYING
THAT, AT LEAST IN MASSACHUSETTS, WE  HAVE TO DO A BETTER JOB
OF GETTING HELP FROM PEOPLE WITH LAND USE EXPERTISE, SUCH  AS
LOCAL PLANNING DEPARTMENTS AND BOARDS, STATE AND REGIONAL PLANNING
AGENCIES; THE REAL ESTATE INDUSTRY,  AND OTHERS,  WlTH  A STAFF  OF
13, THE MASSACHUSETTS AERONAUTICS COMMISSION is TYPICAL OF MOST
STATE AVIATION AGENCIES, AT LEAST OF THOSE THAT HAVE NOT BECOME
SUBSUMED BY THEIR STATE DEPARTMENTS OF TRANSPORTATION.  OUR STAFF
IS MADE UP PRIMARILY OF ENGINEERS AND PILOTS WHICH  IS FINE, BUT
THAT MEANS WE NEED TO MAKE CONTACT WITH THOSE FOLKS WHO CAN DO
FOR LAND USE WHAT MY AGENCY DOES FOR AVIATION.
     HERE ARE A COUPLE OF EXAMPLES:  LIKE  MOST  STATES, MASSA-
CHUSETTS IS DIVIDED  INTO REGIONAL PLANNING AGENCIES WHICH ARE
A  "NATURAL" FOR ALL  KINDS OF AIRPORT PLANNING BECAUSE THESE
AGENCIES WORK WITH ALL OF THE MUNICIPALITIES  IN A  REGION  RATHER
THAN JUST THE COMMUNITY  IN WHICH THE AIRPORT  IS LOCATED,  AND
AIRPORTS ARE A REGIONAL, NOT A  MUNICIPAL,  FACILITY,  TRADITIONALLY,
THESE AGENCIES HAVE  BEEN HIGHWAY ORIENTED  BECAUSE  THEIR FUNDING
COMES FROM HIGHWAY MONEY,  To MAKE  IT  MORE ATTRACTIVE  FOR THESE
AGENCIES TO DO AVIATION  PLANNING, THERE  IS A  BILL BEFORE  CONGRESS
THAT WOULD PROVIDE MONEY FOR THE HIRING  OF AVIATION PLANNERS BY

-------
                        10
THE NATION'S REGIONAL PLANNING ORGANIZATION,
     NOW FOR A MORE SPECIFIC EXAMPLE:   BEVERLY  AlRPORT,  AND
ITS ENVIRONS, WHICH I TALKED ABOUT EARLIER,  HAS BEEN  THE
SUBJECT OF A JOINT LAND USE STUDY, CONDUCTED BY THE GREATER
BOSTON REGIONAL PLANNING AGENCY AT THE REQUEST  OF  THE
THREE COMMUNITIES WHICH HAVE THE AIRPORT AS  THEIR  COMMON
BOUNDARY,  THE METROPOLITAN AREA PLANNING COUNCIL  FINISHED
THEIR WORK JUST IN TIME FOR ME TO BRING A FEW COPIES  ALONG TO
SHOW YOU,  WE DO NOT AGREE WITH ALL THEIR FINDINGS AND
RECOMMENDATIONS, BUT THE IMPORTANT POINT IS  THAT THE  REGIONAL
PLANNING STAFF GOT INVOLVED IN AND APPLIED THEIR SKILLS  TO HELP
RESOLVE SOME OF THESE FRUSTRATING AIRPORT/LAND USE ISSUES,  THEY
ACTUALLY MET WITH THE BEVERLY AlRPORT COMMISSION—POSSIBLY A
FIRST—AND I SUSPECT THEY NOW KNOW A GOOD DEAL MORE ABOUT AIRPORTS,
THIS IS WHAT I MEAN BY ATTRACTING AND INVOLVING NEW RECRUITS,
     LAND USE CONTROLS, AS I STATED AT THE OUTSET, ARE,
UNDOUBTEDLY, A LOCAL AND STATE RESPONSIBILITY;  BUT WHAT  ABOUT THE
FEDERAL ROLE THAT I ALLUDED TO EARLIER,  HERE ARE  SOME IDEAS FROM
THE STATE PERSPECTIVE, VIS-A-VIS GENERAL AVIATION  AIRPORTS,
MONEY, OF COURSE, is ALWAYS WELCOME,  IT SEEMS TO  ME THAT WE NEED
TO BE ABLE TO ACQUIRE LAND OR INTERESTS THEREIN AROUND THOSE
AIRPORTS THAT DO NOT HAVE SERIOUS NOISE PROBLEMS NOW,  IT IS
UNLIKELY THAT THIS WILL HAPPEN UNDER THE EXISTING FEDERAL
GUIDELINES,
     TO GIVE YOU AN EXAMPLE, I HAVE TO GO BACK TO MY EARLIER
WORCESTER STORY,  I EXPLAINED THAT THE 1976 RENEWAL OF ADAP
PERMITTED FEDERAL FUNDING OF UP TO 90% TO BUY LAND OR EASEMENTS
FOR AIRPORT NOISE COMPATIBILITY,  HOWEVER, WHEN THE FAA REGULA-
TIONS TO COVER THIS FINALLY EMERGED,  IT WAS PRETTY CLEAR THAT

-------
                         11
WORCESTER WOULD NOT QUALIFY BECAUSE  THE  NOISE  LEVELS THERE
WERE AND ARE NOT HIGH ENOUGH ACCORDING TO THE  FAA  GUIDELINES,
ALTHOUGH WORCESTER is AN AIR CARRIER AIRPORT—IT HAS TWO  FLIGHTS
A DAY BY DELTA—ITS OPERATIONS ARE ALMOST ENTIRELY GENERAL
AVIATION, AND IT ILLUSTRATES WELL THIS DILEMMA OF  AN AIRPORT
THAT IS NOT NOISY ENOUGH TO TAKE ADVANTAGE OF  FEDERAL  FUNDING,
     AGAIN, ON THE NATIONAL LEVEL, THIS  is THE THIRD YEAR
CONGRESS HAS CONSIDERED FEDERAL NOISE LEGISLATION,  EACH  BILL
HAS CONTAINED PROVISION FOR LAND USE COMPATIBILITY PLANNING,
BUT THE BILLS APPLY ONLY TO AIR CARRIER  AIRPORTS,
     IT  IS NOT MY INTENTION TO BE CRITICAL OF FAA OR CONGRESS
ON THIS  SCORE BECAUSE IT WOULD BE IMPOSSIBLE TO FUND ALL THE
POTENTIAL LAND USE REQUESTS.  NOISE  IS NOISE AND  IT IS UNDER-
STANDABLE THAT FAA GUIDELINES FAVOR THE MORE NOISY AIRPORTS,
THE POINT  IS THAT THIS  USUALLY LEAVES OUT HA AIRPORTS,
     IT  SEEMS TO ME THAT ONE WAY OUT OF THIS BIND  IS THROUGH
BLOCK GRANTS TO THE STATES, AND THERE IS  REASON TO BE OPTIMISTIC
HERE BECAUSE EACH OF THE PROPOSALS TO RENEW ADAP—THAT OF SENATOR
HOWARD CANNON, THE ADMINISTRATION, AND THE NATIONAL ASSOCIATION
OF STATE AVIATION OFFICIALS—PROVIDES FOR BLOCK GRANTS,
     IN  ANOTHER AREA, THE  FEDERAL GOVERNMENT  COULD MAKE  LIFE
EASIER FOR  ALL OF  US BY ELIMINATING  THE  ALPHABET  SOUP WE HAVE
TO DEAL  WITH AND  DESIGNATING  ONE  SYSTEM  FOR MEASURING NOISE
AND DESCRIBING  ITS  IMPACT,
     OBVIOUSLY,  I  HAVE  CONCENTRATED  MORE ON THE LAND  USE APPROACH
TO NOISE ABATEMENT  BECAUSE I  BELIEVE IT  IS THE MOST DIFFICULT
TASK AND ALSO  BECAUSE  IT HAS  BEEN SINGLED OUT"AS I BELIEVE
 IT  SHOULD  BE—IN  THE TITLE OF THIS  CONFERENCE,

-------
                             12
     NOW,  TO RECAP WHAT I  HAVE SAID,   YES,  WE DO  HAVE  A  NOISE
PROBLEM AT OUR GENERAL AVIATION AIRPORTS,   THE SOLUTIONS ARE WELL
KNOWN, AND THEY HAVE BEEN  AROUND FOR  SOME  TIME,
     WE COULD, IN SOME CASES, IMPROVE OUR  TOOLS,
     SOURCE CONTROL is PRIMARILY A FEDERAL AND INDUSTRY  RESPONSIBILITY,
     WE NEED TO MAKE MUCH  BETTER USE  OF THE AVAILABLE  TECHNOLOGY,
     AND STANDARDS FOR LIGHT PROPS MUST BE TIGHTENED,
     OPERATING PROCEDURES. WHICH CAN  PROVIDE MEANINGFUL  NOISE  RELIEF
     TO AIRPORT NEIGHBORS  NOW, ARE SITE SPECIFIC,  THE MAIN EXCEPTION IS
     THE NBAA PROCEDURES,  BASED ON POWER MANAGEMENT,  WHICH ARE APPLICABLE
     AT ANY AIRPORT,  THE  MAJOR TASK  IS SPREADING THE  WORD AMONG
     PILOTS AND GETTING THEM TO USE THE PROCEDURES,  THE AVIATION
     PRESS HAS HELPED ON THIS SCORE,  PARTICULARLY BUSINESS AND
     COMMERCIAL AVIATION WHICH RUNS A MONTHLY NOISE COLUMN,  WE COULD
     USE MORE HELP FROM THE FAA TOWER CONTROLLERS,
     LAND USE CONTROL REQUIRES ACTION FROM LOCAL GOVERNMENTS WHICH
     THUS FAR HAS BEEN THE WEAKEST LINK IN THE CHAIN,   ALTHOUGH WE
     WERE UNSUCCESSFUL, OTHER STATES  SHOULD SERIOUSLY CONSIDER
     LEGISLATION WHICH WOULD GIVE THEM CLOUT  IN THIS PREDOMINANTLY
     LOCAL MATTER,
          OUR ABILITY TO PURCHASE LAND NEAR GA AIRPORTS  FOR NOISE
     COMPATIBILITY WOULD BE  IMPROVED IF THE CHANCES WERE BETTER OF
     GETTING  FEDERAL MONEY TO HELP DO THE JOB,  TOWARD THIS
     END,  WE  NEED TO SEE THAT BLOCK GRANTS TO THE STATES ARE PROVIDED
     FOR  IN THE RENEWED ADAP,

                      THE TOWN OF RYE



                            AND



                 THE COUNTY OF WESTCHESTER



               REGARDING ECONOMIC DEVELOPMENT



     The Town of Rye and the County of Westchester are participating



in the Airport Master Plan study for the westchester County Airport



and its accompanying Airport Noise control and Land Use Compatibility



study.



     The ""own of Kye is contiguous with t'.:e Westchester County



Airport, and i.s unique in that there are in the approach areas  to



Runway 34 some 300 acres of developable land in the Town of Rye.



The appropriate development of this land is of particular concern



both to the Town of Rye and to the County of Westchester, both



because of its relationship to the County airport and  in view of its



economic benefits.  As a part of the master plan and AJJCLUC studies,



the Town and the County are cooperating in the study of the appropriate



forir. and type of development 'or this specific area.



     The Town of Rye has designated this area as a critical area



on which it wishes to cooperate with the County in promoting sound



economic development for the highest and best possible use in our



existing circumstances.  Accordingly, it is hereby agreed that  the



County of Westchester and the Town of Rye will continue the cooperation



started under the Airport Master Plan and ANCLUC studies and will

-------
actively  seek  the  appropriate  development  of this land by

such developers  and  with  sucn  land  usot> as mill be of great

value  to  the Town  of  Hye  and yet  be compatible with the

requirements relating  to  public  safety  and welfare for the use

of  land us  the vi.-.mity of  the County Airport.  Both the County

and  Ji" Town agree that a necessary and immediate priority of this

joint  economic development  effort will  ue  the planning of an

effective and  appropn&tp access  road system, linking route 684

with tho  developable  land in the  Town of Rye, designed to improve

the va 1 in- and  viability for the land for prudent economic development.

     In support  of tins agreement,  the  Tovn pledge:, to pursue in

pood faith  its responsibilities  In  the  preparation of the Airport

Master Plan and  ANCLUC study agreement, and to cooperate with the

County in seek ing  arid  "importing  appropriate development options.

Tin  County of  'AVstchestcr pledges the staf' support of the County

I* rsor.nel , particularly thosi-  of  the Office of Economic Development,

tne Department of  Planning,  the Department of Public Works, and the

Department of Transportat:on,  in  obtaining and promoting the

Effectiveness  of Aircraft Takeoff
Thirty-six airplane departures, consisting of two weights for each of three types of
aircraft executing six takeoff procedures, were evaluated for noise abatement
effectiveness by William C. Sperry. t The evaluation was based upon comparisons
of noise levels on the ground and  population highly annoyed. The results indicate
that although no single takeoff procedure is most effective for noise abatement
everywhere, two complementary procedures offer the greatest benefit for the
most people.1
*.*
Aircraft are capable of utilizing a variety
of safe departure procedures, each of
which generates different noise levels
and different noise exposure patterns
for people on the ground  In general,
aircraft initiate takeoff roll with high
thrust and small-to-moderate flap set-
tings (takeoff thrust and flaps)  Shortly
after lift-off, they retract landing gear
and by 400 ft (122 m) height above
the airport (HAA) reach  a stabilized
all-engine climb speed which  permits
them  to climb at a safe but relatively
large  gradient At specified values of
 HAA, depending upon the takeoff pro-
 cedure,  the aircraft will retract flaps
 (cleanup) and reduce or cut back the
 thrust to a specified setting At some
point in space below 10,000 ft
 (3048 m) HAA, the aircraft will climb in
 a clean  configuration,  at climb thrust.

                  This paper reviews six takeoff proce-
                dures and evaluates their effectiveness
                for noise abatement  The supporting
                analysis consisted of five  calculations
                the noise  levels along the flight track
                (projection of the  flight path on the
                ground) produced by two weights each
                of three airplanes,  the areas enclosed
                within six single-event noise level con-
                tours, ihe  areas enclosed within six
                multi-event noise exposure contours.
                assuming 200 takeoffs per clay, the
                numbers of people enclosed within the
                noise exposure contours, assuming a
                constant population density  of 5000
                people/mi^ 1931 people/km2), and the
                number of people highly annoyed as a
                 result of each takeoff procedure
                   The six takeoff procedures are used
                 or are capable of being used in routine
                 departures except as noted Their effec-
                 tiveness is evaluated, however, only in
                 regard to noise abatement, while other
                 factors such as safety, fuel consump-
                 tion, air pollution, cost, block time, and
                 maintenance must also be considered
                 in determining the most feasible com-
                 mercial takeoff procedures
    Takeoff Procedures

  A noise abatement takeoff proce-
dure is an aircraft departure schedule
consisting of three flight path segments
which can be identified by their princi-
pal operational activities roll and initial
climb,  thrust reduction, and normal
climb  Within each segment may be
several sections in which the a'rplanc
conducts additional activities such as
gear and flap retractions, accalerations
to specified speeds, and thrust changes
The locations at which the activities are
initiated and their magnitude and dura-
tion are the factors that deletmme the
takeoff procedures'  effectiveness for
noise abatement
  The pnncipal differences in takeoff
procedures that influence the noise ex-
posure patterns on the  ground are
cleanup before initiation of thrust cut-
back (C/B), or vice versa, extent of cut-
back thrust (CBT), HAA for cleanup
and initiation of CBT. and HAA for
reapplication of thrust when CBT is less
than maximum climb thrust (MCT)

 .  FAR 36. The test conditions for air-
 craft noise certification permit demon-
 stration of compliance with noise re-
 quirements at the takeoff  measuring
 point by reducing TOT to a CBT before
 cleanup equal to the thrust required for
 one-engine-out  level flight  or a four
 percent climb  gradient, whichever
 thrust is greater.4 The FAR  36 proce-
 dure,  however,  is not used in routine
 operations at airports. It should be in-
 vestigated, therefore, for its suitability
 as a standard operation procedure. If it
 is determined to have less noise control
 advantage than  the others,  considera-
 tion should be given to eliminating it
 from the FAR 36 takeoff test conditions
 and replacing it with some more effec-
 tive procedure.

 the DCA  procedure should be com-
 pared  with those of the  others to  de-
 termine whether the  DCA procedure
 should be used  at other airports  or
 whether it should be supplanted at
 Washington National Airport by a more
 effective method. The DCA procedure
 would reduce TOT to a CBT equal to

 current types  of  engines, due to the
 excessive length of time they would be
 forced to operate with maximum heat
 and stress. The purpose of considering
 this procedure is mainly for reference;
 that is, to compare the noise control
 benefits of other takeoff procedures
 with those of one which would position
 aircraft as high  as possible in the least
 time and shortest flight track distance.
 If,  however, the comparisons indicate
 that the Maximum Thrust climb proce-
 dure would result  in  superior  noise
 abatement, the environmental consid-
 erations would add support to ongoing
 research and  development  directed
 toward  increasing  allowable engine
 operating times under maximum thrust
 conditions.
   Detailed descriptions of these takeoff
 procedures are included in Figs.  1 to 6.
 The procedures can be placed into one
 of  three broad categories regarding
 noise abatement, depending upon the
 location of noise-sensitive areas relative
 to the takeoff runway:  close-in, near-
 downrange, and far-downrange.  Each
 category would permit less noise at the
 designated location than would result
 from the others. All of the procedures
 except Maximum Thrust involve reduc-
 tion in thrust, the differences being the
 position of  the airplane when  thrust
 cutback occurs, the extent of  the  cut-
 back, and the position of the airplane
 when cleanup is initiated.
  From Figs. 1 to 6 it is apparent that to
 determine  the performance of an
 airplane in terms of its position, thrust,
 airspeed, and noise-generating capabil-
 ity, a great deal must be known about
 the airplane. Most of the necessary in-
 formation,  however,  is  not  readily
 available except to the airplane manu-
 facturer and operator. Some data used
 for this investigation were found in the
 open literature,  other  data  were  ob-
 tained  by request from the manufac-
 turers and operators, and the remain-
 der were determined by interpolation
 and extrapolation of given data.
  Examples of published data are Refs.
 6 to 19, which report the results of an
 FAA-sponsored study  on the  noise
generated by eight  types of aircraft
 while performing certain flight proce-
dures.  The airplane takeoff perform-

-------
ance data, although limited in scope,
and the  airplane noise characteristics
given in Refs. 6 to 19 were invaluable
for this investigation.
   Each of the six takeoff procedures
was evaluated with respect to its noise
abatement capability for three types of
turbofan airplanes. Two weights were
chosen for each airplane, representing
high-use  heavy  and  light takeoff
weight, to determine whether the noise
abatement capabilities of each proce-
dure arexonsistent for practical ranges
of airplane weights. The three types of
airplanes chosen for this investigation
are the  B727-200 (QN),  B737-200
(QN), and B707-320B. The notation
QN means quiet nacelle, which desig-
nates that appropriate portions of the
gas flow passages of the engine nacelles
have been lined with sound absorption
material  (SAM).
   This  investigation  consisted of
analyzing  the climbout performance
and noise levels for  thirty-six aircraft
operations — six airplanes (three types,
two weights each)  performing six
takeoff procedures. Two of the three
airplanes considered are among the
noisiest of all jet aircraft and among the
most numerous. Thus, the most effec-
tive noise abatement takeoff  proce-
dures for the two airplanes could effect
a significant reduction in aircraft noise
exposure on a national basis.
   Analytical Approach and
          Assumptions

   The evaluation of the effectiveness
 for noise abatement of the six takeoff
 procedures delineated in Figs. 1 to 6
 was based upon an analysis of the six
 airplanes operating in an assumed
 airport/community configuration. The
 airport was assumed to have a single
 runway, with all departures in the same
 direction. The land around the airport
 was  assumed to have  a population
 density of 5000 people/mi2 (1931
 people/km2), which is representative of
 a moderately urban community.
   The airplanes were assumed to fly to
 a particular point in space along flight

 paths lying in the vertical plane contain-
 ing the center line of the airport run-
 way. Each airplane was assumed to fly
 to  10,000  ft (3048m)  HAA  while
 executing each of the six takeoff proce-
 dures. At 10,000 ft (3048 m) HAA, the
 airplanes were assumed to level off. re-
 duce thrust  to horizontal thrust (HZT),
 and proceed horizontally to a 220,000
 ft (67,056 m) distance from brake re-
 lease (DFBR). The latter distance is ar-
 bitrary; it was chosen to be somewhat
 greater than the  DFBR at 10,000  ft
 (3048 m)  HAA  required for  the
 airplane having the lowest ratio of
 thrust  to weight.
  The purpose of including a horizon-
tal flight segment  was that in normal
operations,  aircraft are frequently di-
rected  to proceed rapidly  away from
the airport before reaching cruise al-
titude.  This  vectoring process usually
occurs at any height  above 3000  ft
(914 m) HAA — the lower the height,
the greater  the  potential  for adverse
noise impact. Consequently, for this in-
vestigation,  the performance  model
chosen for all airplanes assumed that
vectoring, if done at  all,  would not
occur until after the airplanes reached
10,000 ft (3048 m)  HAA. That  as-
sumption permitted evaluation of  the
takeoff procedures, uncomplicated by
vectoring,  to a  significant height;
showed the  influence of vectoring at  a
height  that would have little or no po-
tential  for adverse noise impact; and
served as an implicit recommendation
(by the author) that 10,000 ft (3048 m)
HAA be the lower limit for vectoring
unless  safety requirements should dic-
tate otherwise.
  The first step in the analysis consisted
of calculating the single-event  noise
levels,  in terms of Effective Perceived
Noise  Level  (EPNL), along the flight
track that would be produced by each
of the six airplanes flying to the particu-
lar point in space (10,000 ft [3048 m]
HAA and 220,000 ft [67,056m]
DFBR) while executing the takeoff pro-
cedures.  The results of those calcula-
tions are plotted in  Figs. 7a to 7f for the
two weights of the B727-200  (QN)
airplane.
  The  second step  consisted of cal-
culating the areas enclosed by the con-

-------
tours of six EPNL levels: 85, 90, 95,
100,  105, and  110 dB.  The closure
points of the contours are indicated by
the corresponding noise  levels  along
the flight tracks determined in the first
step. The results of the second step rep-
resent land areas around the airport
exposed to specific noise levels result-
ing from single-event departures  of the
individual  airplanes.  No assumption
was made about the proportion  of the
noise-exposed areas  that would lie
within airport property.
   The  third step in the  analysis as-
sumed  that each of the six airplanes
executed 200 departures per day, from
0700 to 2200 hours, for each of the six
takeoff procedures. The areas enclosed
by the contours of six Noise Exposure
Forecast (NEF) levels were calculated:
20,25,30,35,40, and 45 dB. The NEF
levels were converted to Day-Night
Sound  Levels (Ldn) by adding a con-
stant 35 dB to the NEF levels, yielding
Ldn 55, 60, 65, 70. 75, and 80 dB. The
constant 35 dB is the approximate rela-
tionship between NEF and L()n recom-
mended by the US Environmental Pro-
tection  Agency (EPA)  in the Levels
Document.20
   The results of the third step represent
land areas around the airport exposed
to specific cumulative noise levels pro-
duced by multi-event departures  of the
individual airplanes. The choice of 200
departures per daytime hours was arbi-
trary: it represents a  high  but possible
operational rate  that emphasizes the
differences between  the effectiveness
of the  takeoff procedures  for  noise
abatement.
   The fourth step in the analysis in-
volved calculating the numbers of
people enclosed within each of the six
Ldn contours,  assuming a  constant
population density of 5000 people/mi'
(1931 people/km2). Also calculated
were  the numbers of people enclosed
within each 5-dB increment of L,,n (that
is, 55 to 60 dB, 60 to 65 dB, and so on),
which were required  for  determining
the population impacted by noise.
   The fifth step consisted of calculating
the highly annoyed population (HAP)
in accordance  with  the method de-
veloped by the National Research
Council  (NRC).2' Three relationships

  Flight Track Noise Levels

  Figs. 7a to 7f illustrate for two weights
of the B727-200 (QN) type airplane the
variation of noise levels along the flight
track for each of the six takeoff proce-
dures. The lettered symbols refer to lo-
cations or activities of the airpk-.nes that
are important to the takeoff procedures
and correspond to the identification let-
ters given in the illustrations  and de-
scriptions of Figs. 1 to  6. For example,
the letter F always indicates the noise
levels on the ground at the given DFBR
produced  by the airplanes when they
first reach  10,000 ft (3048 m)  HAA. at
MCT and at HZT. The letter D in Figure
7b for the ALPA/NWA Max. C/B pro-
cedure  indicates  the  noise levels at
DFBR produced by the airplanes when
they reach the point at 4000 ft (1219 m)
HAA at which  thrust  is begun to  be
gradually reapplied from CBT to MCT.
  The  variation of noise levels along
the flight track,  resulting from the first
step in  the analysis, provided the basic
data for judging the six takeoff proce-
dures'  effectiveness for noise abate-
ment. Other information, such  as areas
and population exposed to  various
levels of noise and highly annoyed
population, were necessary to establish
quantitative comparisons of the proce-
dures.  However, certain qualitative
judgments were made  from Figures 7a
to 7f and verified quantitatively after

-------
completing the remaining four steps in
the analysis.
   The first action in the qualitative
judgments was to divide  the proce-
dures into two classifications identified
by the sequential applications of thrust:
TOT-CBT-MCT,  which includes the
ALPA/NWA Max. C/B,  FAR 36, and
DCA procedures,  and TOT-MCT,
which includes  the AC 91-39 and
ALPA/NWA Min. C/B procedures. The
second  action was  to  further divide
each -classification into two parts  iden-
tified by the priorities given to cutback
and cleanup: cleanup  before  C/B,
which includes the ALPA/NWA  Max.
C/B and ALPA/NWA Min. C/B proce-
dures, and cleanup  after C/B, which
includes the AC  91-39,  FAR 36, and
DCA procedures.  The Maximum
Thrust procedure was  not included
among those classifications because it
has no thrust reduction  and its effec-
tiveness was judged after the other five
were evaluated. The classifications are
shown in Table I.
   Determination of the effectiveness of
the procedures for  noise  abatement
was made by comparing the  noise
levels along the flight track relative to
the three categories of distance  from
the airport: close-in,  near-downrange,
and far-downrange. The three
categories are broad and without sharp
dividing lines. Roughly, close-in repre-
sents the land area between the airport
and the DFBR, where the noise reduc-
tion due to cutback is indicated; near-
downrange represents the land  area
between close-in and the DFBR, where
the noise increase is indicated because
of reapplication of thrust from CBT to
MCT; and far-downrange represents
the land area beyond near-downrange.
In making  the judgments, the near-
downrange category was given  most
emphasis. On a practical basis, close-in
would include airport  property  and
other  noise-compatible  land use. and
the far-downrange noise exposure
would be lessened by the normal dis-
persion  of aircraft  as  they proceed
farther from the airport.
   Compare first the  classification
TOT-CBT-MCT  with cleanup  after
C/B, which represents the FAR 36 and
DCA  procedures. Close-in: DCA is

noisier, but only for a relatively short
distance along the flight track. Near-
downrange: DCA is noisier for the
lightest weight airplane and FAR 36 is
noisier for the heaviest weight airplane.
Far-downrange: FAR 36 is noisier for
the lightest weight airplane and DCA is
noisier for the heaviest weight airplane.
In summary, there is not enough differ-
ence in noise control effectiveness be-
tween the two procedures to choose
one over the other.
  Next,  compare  the DCA and
ALPA/NWA  Max. C/B procedures.
Close-in: ALPA/NWA Max. C/B  is
noisier, but only for a relatively short
distance along the flight track. Near-
downrange:  DCA is  noisier  for both
airplane  weights. Far-downrange:
ALPA/NWA Max. C/B is noisier for the
lightest weight airplane and DCA is
noisier for the heaviest weight airplane.
In summary, although there are some
locations along the flight track where it
is noisier, the ALPA/NWA Max. C/B
procedure was judged to be substan-
tially more  effective for noise abate-
ment  than  was the DCA  procedure,
primarily  due to  its superior effective-
ness near-downrange.
  Now  compare the  classification
TOT-MCT, which  represents the
ALPA/NWA Min. C/B and AC 91-39
procedures, the former utilizing
cleanup before cutback and the latter
cleanup after cutback.  Close  in:
ALPA/NWA Min. C/B  is noisier, but
only for a relatively short distance along
the flight track.  Near-downrange and
far-downrange (categories combined
because there is  no  reapplication of
thrust): AC 91-39 is  noisier for both
airplane  weights. In summary, the
ALPA/NWA Min. C/B procedure was
judged more effective for noise abate-
ment.
  Next,  compare the  ALPA/NWA
Max.  C/B and ALPA/NWA Min. C/B
procedures. Close-in:  both  procedures
produce  identical noise levels. Near-
downrange: the Min. C/B procedure is
substantially noisier for both airplane
weights. Far-downrange: the Max. C/B
procedure is substantially  noisier  for
both airplane weights. In summary, be-
cause of  its superior effectiveness
near-downrange, the  ALPA/NWA

-------
 Max. C/B procedure was judged more
 effective for noise abatement.
   Finally,  compare the ALPA/NWA
 Max. C/B and Maximum Thrust proce-
 dures. Close-in: the procedures pro-
 duce identical  noise levels.  Near-
 downrange: Maximum Thrust is sub-
 stantially  noisier.  Far-downrange:
 ALPA/NWA Max. C/B is noisier.  In
 summary, because of its superior effec-
 tiveness  near-downrange,  the ALPA/
 NWA Max. C/B procedure was judged
 more effective for noise abatement.
   The qualitative comparisons of the
 noise levels along the  flight track pro-
 duced by the six takeoff procedures re-
 sulted in the ALPA/NWA Max. C/B
 procedure being judged most effective
 for noise abatement.  That judgment
 was based primarily on its superior ef-
 fectiveness near-downrange. It  is rec-
 ognized, however, that at some air-
 ports, noise-sensitive communities are
 located far-downrange and not  near-
 downrange, and that a more effective
 takeoff procedure should be available
 for use in those cases. It was decided,
 therefore, that the  two ALPA/NWA
 procedures would collectively be most
 effective for noise control. The two pro-
 cedures are so similar  from an aircraft
 operations standpoint that there would
 be very little increase in work load for
 the pilot to become proficient in both.
 Population Highly Annoyed

  The quantitative evaluation of the ef-
fectiveness for noise abatement of the
six takeoff procedures is illustrated by
the bar charts of Figs. 9a, 9b, and 9c for
six airplanes (two weights each of three
types of airplanes). The measure of ef-
fectiveness is the highly annoyed popu-
lation (HAP) exposed to cumulative
levels of noise equal to L«n 55 dB or
greater; the lower the HAP, the more
effective the  procedure.
  It is interesting to compare the results
of the previously determined qualita-
tive  analysis of the B727-200 (QN)
type airplane with the quantitative  re-
sults of Fig.  9a.  For both airplane
weights, the ALPA/NWA  Max. C/B

the ALPA/NWA Max and  Mm  C/B

         Conclusions

  Each  of the aircraft takeoff proce-
dures has both advantages and disad-
vantages for noise control, depending
upon the  location of noise-sensitive
communities A procedure that reduces
thrust before cleanup has the advan-
tage of  abating noise sooner than a
procedure  that reduces  thrust  after
cleanup  However,  the  noise abate-
ment resulting from the former may be
less than the latter and may  occur too
close to the airport to benefit many
people  A procedure that employs a
large thrust reduction has the advan-
tage of maximum noise abatement, but
would be of no value if noise-sensitive
communities were not located where
that advantage would be  realized
  A procedure  that reduces power
below climb thrust in order to minimize
the noise exposure for one community
must ultimately reapply power to climb
thrust,  which may increase  Jhe expo-
sure for another community  When
companng two procedures,  one with
larger thrust cutback than the other, it is
apparent that there will be a crossover
point at which both procedures will
produce the same noise level on  the
(light track Inside the crossoveT point
(toward the airport), (he larger cutback
procedure will produce less noise,  but
outside the crossover point, the reverse
is true
  As discussed above, the results of the
analysis indicate that no single takeoff
procedure is most effective for noise
abatement everywhere   However, in
considering both weights of the three
airplanes investigated, a  pattern
evolved On balance, the takeoff pro-
cedures that cleaned up before thrust

-------
cutback offered the greatest potential
for maximum noise reduction for the
largest number of people That is. the
ALPA/NWA maximum and minimum
cutback procedures evidenced definite
noise control supenonty over the other
procedures when compared in terms of
highly annoyed population.
  It should be emphasized that the two
ALPA/NWA procedures  are identical
during their most complex aspects, that
is, cleanup and initiation  of thrust cut-
back  The only differences  in the two
piocedures are the depth of cutback
and the reapplication of power at 4000
ft (1219 m) HAA, both of  which are not
complicated and are executed  when
the airplane is well stabilized In other
words, if two takeoff procedures make
sense for  noise  abatement, the  two
ALPA/NWA procedures  would result
in the least increase in pilot work load
because of their near similarity
  These conclusions were based upon
an analysis of the performance of only
three types of airplane B727-200
(QN),  B707-320B,  and B737-200
(QN)  Many other types exist, and un-
less their takeoff performance can be
evaluated in the same manner as those
three, it cannot be concluded catego-
rically that the ALPA/NWA Max  and
Mm  C/B  procedures would be  most
effective for noise abatement Neverthe-
less, two of the three airplanes evalu-
ated are among the noisiest and  most
numerous of all commercial air earners
The most effeciive takeoff procedures
for the two airplanes would result in a
significant  reduction in noise exposure
around  most air earner airports
   One or  the other of the ALPA/NWA
procedures would probably  be the
most effective for noise abatement of all
six takeoff procedures  for any jet-
propelled  airplane What is not so cer-
tain, however, is which of  the two —
Max  C/B  or  Mm  C/B  — would be
more effective for aircraft  other than the
three analyzed  here For  example,
compare the results for the B727-200
(QN) and the B737-200  (QN) with the
results  for the B707-320B. the  latter
having higher bypass ratio engines than
the others Figs  9a and  9c show that
Max. C/B is clearly more effective than
                                                                  20

   The FAA has recently issued a new
 advisory circular, AC 91-53,  which
 supersedes AC 91-39 " The new advi-
 sory encourages cleanup before or dur-
 ing cutback, and both ALPA/NWA
 procedures would lie within the FAA
 recommendations  Furthermore, AC
 91-53 recommends that airplanes with
 high-bypass-ratio engines should not
 reduce thrust below climb thrust on de-
 parture Thus, the new advisory sup-
 ports the  conclusions reached by this
 investigation
   The Maximum Thrust takeoff proce-
 dure was  included in this investigation
 to determine whether there would be
 an advantage for noise abatement in
 positioning aircraft as high as possible
 in the shortest DFBR Figs  9a and 9c
show that for the airplanes propelled by
the lowest  bypass ratio engines,  the
Maximum' Thrust procedure was  the
least effective of all six procedures for
both weights of the airplanes  Fig. 9b
shows that for the B707-320B,  the
Maximum Thrust procedure, while not
the least effective of all six, was clearly
less effective than the two ALPA/NWA
procedures  In  summary, the
Maximum Thrust takeoff procedure did
not evidence any significant advantage
   The detailed descnptions of the six
takeoff procedures given in Figs  1 to 6
specify  particular aircraft activities at
specific locations It is not expected that
the effectiveness of the procedures  is
very sensitive  to small changes in the
activities or locations For example, the
procedures that require cutback before
cleanup require cutback at either 1000
or 1500 ft (305 or 467 m) HAA and the
procedures that require cleanup before
cutback require initiation of cleanup at
 1000 ft (305 m) HAA There is proba-
bly an optimum HAA for noise  abate-
ment effectiveness for those activities
for each of the procedures, but it is not
expected that within the ranges allowa-
ble for safety, the relative order of effec-
 tiveness would change. Similar conclu-
sions  are  probably  valid for other
activities, such as reapphcation of thrust
 and cleanup after cutback, although a
 sensitivity analysis was not made for
 this investigation
   One final conclusion resulting from
 this investigation is of a cautiondry na-
 ture Although the procedures  that
 clean up before cutback (ALPA/NWA
 Max and Mm C/B) are the most effec-
 tive for current airplanes with very low
 and low bypass ratio engines and are
 projected to  be the  best  for current
 airplanes with  high-bypass-ratio en-
 gines, they may not be most effective
 for  less noisy airplanes of the  future
 The reasoning behind that warning is
 that future types of airplanes are ex-
 pected to be substantially less noisy
 than the current airplanes, with a  con-
 sequent shnnking of the  noise  level
 contours The result would be that a
 greater proportion of the high noise ex-
 posure level areas would be included
 within the airport fences or other
 noise-compatible  boundaries than at

-------
present  It  is possible, therefore, that
the  takeoff procedures that  initiate
thrust reduction at maximum HAA and
minimum  DFBR would  have maxi-
mum  noise abatement effectiveness
  In other  words, the procedures that
clean up after cutback might prove to
be more effective for noise abatement
for relatively  low noise level airplanes
than would the procedures that clean
up before cutback If  so. the explana-
tion is that a large climb gradient initially
would place enough of the high noise
exposed areas within the airport fence,
so that what happens at later stages of
the procedure  would not be of  much
importance  The  conclusion is that
when new types of airplanes become
substantially less  noisy, the takeoff pro-
cedures should  be  reevaluated for
noise abatement effectiveness

       REMEDIAL MEASURES FOR DEALING WITH NOISE ASSOCIATED
          WITH GENERAL AVIATION ACTIVITY - A  CASE STUDY
              PRESENTED BY W, J, CRITCHFIELD,  A.A.E,
                      TORRANCE, CALIFORNIA
          TO  THE  CONFERENCE ON GENERAL  AVIATION AIRPORT
                   NOISE  AND LAND  USE PLANNING
                         ATLANTA,  GEORGIA
                          OCTOBER  4, 1979

     GENERAL AVIATION AS  A MODE OF TRANSPORTATION  HAS  COME OF AGE,
     UNFORTUNATELY, THIS  CONVENIENCE AND SOPHISTICATION HAS DEVELOPED
ADDITIONAL PROBLEMS WHICH PLAGUE  GENERAL AVIATION,   MOST  AIRPORTS
WHICH MAKE GENERAL AVIATION  A  CONVENIENT AND  EFFICIENT MODE OF
TRANSPORTATION HAVE TWO  THINGS IN  COMMON,   THEY ARE  LOCATED IN A
CROWDED URBAN AREA, AND  THEY ARE  HEAVILY USED,
     TORRANCE MUNICIPAL  AIRPORT  is NO  EXCEPTION,   IT is LOCATED IN THE
SOUTH BAY AREA OF Los ANGELES COUNTY  SERVING  A POPULATION IN EXCESS OF
2 MILLION,  IT IS ALSO ABOUT THE  12TH  BUSIEST AIRPORT IN THE NATION,
     THE AIRPORT WAS FIRST DEVELOPED  AS A FLIGHT STRIP BY THE BUREAU
OF PUBLIC ROADS IN THE LATE 1920's,  IT WAS TRANSFERRED TO THE U,S,
CORPS OF ENGINEERS AND DEVELOPED AS A FIGHTER STRIP IN THE EARLY AND
MIDDLE 40's,
     IT WAS ACQUIRED BY THE ClTY OF TORRANCE  IN 1948,  AT THAT TIME
THE AIRPORT WAS SURROUNDED BY AGRICULTURE, OIL FIELDS, AND SOME
INDUSTRIAL  USE,  THE COMMUNITY, NOW THE ClTY  OF LOMITA, TO THE EAST,
WAS MOSTLY  AGRICULTURAL USE RESIDENTIAL LOTS,
     THE AIRPORT AND  ITS SURROUNDING COMMUNITY REMAINED  IN THIS
GENERAL LAND  USE PATTERN FOR 10 YEARS,

-------
     IN 1958 THE CITY OF TORRANCE TOOK ACTION TO DEVELOP THE
AIRPORT TO MEET THE GROWING NEED FOR GENERAL AVIATION,   OVER THE
NEXT 5 YEARS THE CONTROL TOWER WAS CONSTRUCTED,, THE SECOND RUNWAY
WAS BUILT, TAXIWAYS, PARKING APRONS, LIGHTING, AND HANGARS WERE
CONSTRUCTED,
     CONCURRENTLY, HOUSING AND APARTMENTS WERE DEVELOPED AROUND THE
AIRPORT,
     THE OBJECTIONS TO AIRCRAFT NOISE AND CONFLICTING LAND USE
PATTERNS FIRST BECAME EVIDENT IN 1965,  THE ClTY OF TORRANCE STARTED
ITS FIRST REMEDIAL MEASURE AT THAT TIME,
     THIS DEALT WITH LAND USE,  THE AREA IMMEDIATELY WEST OF THE
AIRPORT HAD BEEN PERMITTED TO DEVELOP WITH POOR QUALITY HOUSING FOR
SINGLE FAMILY AND MULTIPLE FAMILY RESIDENTIAL USE,
     MANY OF THE HOUSES WERE FREEWAY MOVE-INS DISPLACED BY FREEWAY
RIGHT-OF-WAY ACQUISITION AND RELOCATED,  IN ORDER TO PROTECT THE
AIRPORT, THE ClTY OF TORRANCE INITIATED A FEDERAL HOUSING AND URBAN
DEVELOPMENT REDEVELOPMENT PROJECT TO CONVERT THE RESIDENTIAL LAND
USE TO LIGHT INDUSTRIAL,
     THE PROJECT AMOUNTED TO $7 MILLION ON 1/3 MATCHING GRANT,  LOANS
AND LOCAL FUNDING,
     THE ORIGINAL PROJECT CONVERTED RESIDENTIAL USES IMPACTED BY
AIRPORT OPERATIONS  TO LIGHT  INDUSTRIAL, OFFICE, AND COMMERCIAL  USES
WHICH  ARE COMPATIBLE AND,  IN FIVE  INSTANCES,  HAVE CREATED LIGHT
INDUSTRIAL  COMMERCIAL OFFICE USES WITH  DIRECT  ACCESS TO THE AIRPORT,
     TODAY  IT  is  AN EXAMPLE  OF  EFFECTIVE REDEVELOPMENT,
     ANOTHER PROJECT UNDER  STATE  GUIDELINES  USING  LOCAL FUNDS WILL
TAKE PLACE  IMMEDIATELY  NORTH OF THE EXISTING  MEADOW PARK  REDEVELOPMENT
PROJECT,
      IN  1965 THE  CITY TOOK  OTHER  LAND  USE MEASURES WHICH  CONTINUE  TO
BE UTILIZED,

-------
     THESE ARE THE ACQUISITION QF AVIGATION EASEMENTS WHICH REQUIRE
HEIGHT LIMITS, GRANT THE RIGHT OF FLIGHT,  AND, IN SOME INSTANCES,
REQUIRE ACOUSTIC TREATMENT,
     AVIGATION EASEMENTS ARE OBTAINED BOTH AS DEED RESTRICTIONS ON
TRACTS FOR NEW DEVELOPMENTS AND AS A CONDITION OF LAND USE CHANGES
OR MODIFICATIONS SUCH AS CONDITIONAL USE PERMITS, LOT SPLITS, AND
OTHER LAND USE MODIFICATIONS,
     ACOUSTIC CONSTRUCTION IS ALSO REQUIRED FOR NEW STRUCTURES HAVING
CRITICAL USES IN THE COMMERCIAL INDUSTRIAL AREAS,  THIS INCLUDES THE
HOSPITAL AND MEDICAL FACILITIES WHICH REQUIRE LOW INTERIOR NOISE LEVELS,
     AVIGATION EASEMENTS ARE OBTAINED JUST AS STREET, SIDEWALK, SEWER,
AND OTHER EASEMENTS ARE OBTAINED FOR NEWLY DEVELOPING PROPERTY OR
PROPERTY REQUESTING MODIFICATION OF EXISTING USES,
     IN CONGESTED URBAN AREA LAND USE PLANNING, RE-USE, DEED RESTRICTIONS,
AND AVIGATION EASEMENTS ARE LIMITED AS REMEDIAL MEASURES,
     THERE STILL EXIST RESIDENTIAL USES WHICH ARE IMPACTED BY GENERAL
AVIATION AIRCRAFT OPERATIONS.
     IN 1970  AIRCRAFT NOISE, TOGETHER WITH CHANGING LAND USE, RAISED
QUESTIONS  IN  THE MINDS OF THE ClTY COUNCIL AND MEMBERS OF THE COMMUNITY,
     A PROCESS WAS  STARTED FOR REVIEWING THE GOALS FOR THE AIRPORT
WHICH RESULTED  IN DEVELOPMENT OF THE NEW AlRPORT M.ASTER PLAN AND THE
NOISE ABATEMENT PROGRAM BEING USED TODAY,
     BEFORE MAKING  ADDITIONAL ADJUSTMENTS, IT  is ESSENTIAL TO PERFORM
AN OBJECTIVE  ANALYSIS AND EVALUATION OF THE ENVIRONMENT OF THE AIRPORT,
     THIS  INCLUDES  NOT ONLY THE COMMUNITIES SURROUNDING THE  AIRPORT,
BUT  THE AIRPORT  ITSELF,  ITS  USE, TYPES AND CLASS OF AIRCRAFT, AND  THE
SPECTRUM  OF EXPERIENCE OF THE AIRCRAFT OPERATORS,
                                 -3-

-------
     YOU MUST IDENTIFY THE PROBLEMS AND THE PROBLEM AREAS,  THE
AVERAGE GENERAL AVIATION PILOT DOES NOT PERCEIVE HIS OPERATION INTO
AND OUT OF THE AIRPORT AS A PROBLEM,  THE PILOT GENERALLY HAS NO
PERCEPTION OF THE NOISE IMPACT OF HIS AIRCRAFT OPERATIONS ON THE
ENVIRONMENT ON THE GROUND,
     IT'S AKIN TO TURNING A DRIVER LOOSE ON A PARKWAY OR A FREEWAY
WITHOUT A SPEEDOMETER AND CAUTIONING HIM NOT TO EXCEED THE SPEED LIMIT,
     NOISE  IS THE PRIMARY PROBLEM,  SAFETY MAY BE BROUGHT FORTH AS A
PROBLEM, BUT GENERALLY  IT IS SECONDARY AND IS USED TO SUPPORT RESISTANCE
TO NOISE  IMPACT,
     THE MAGNITUDE OF THE NOISE MUST BE ANALYZED,
     THE  SOURCE,  IN TERMS OF THE AIRCRAFT TYPE, ITS POWER PLANT,
PROPELLER NOISE,  EXHAUST NOISEj
     TECHNIQUE -  THE  PILOT'S EXPERIENCE, HIS FAMILIARIZATION WITH THE
AIRCRAFT, AND  ITS CAPABILITY, THE  LIMITATIONS OF  ITS PERFORMANCE, AND
 ITS  NOISE,  AND WITH THE AIRPORT AREA,
     ANOTHER ELEMENT  OF THE NOISE  PROBLEM  is FREQUENCY OF OCCURRENCE -
THE  VOLUME  OF THE NOISE MAY BE LOW, BUT MANY AIRCRAFT F1AY BE OPERATING
 IN A TRAINING MODE, AND THE FREQUENCY  OF OCCURRENCE OF THE OPERATIONS
MAY  BE EVERY 45  SECONDS,  THE NOISE MAY NOT BE LOUD, BUT  IT  IS  STEADY
OR RECURRENT,
     THE  THIRD ELEMENT  IS TIME OF  OCCURRENCE,  YOU MUST ANALYZE THE
TIME OF OCCURRENCE OF THE NOISE  EVENTS IN  TERMS OF THE COMMUNITY'S
 CYCLE  - WHAT ARE PEOPLE DOING AT THE TIME  OF YEAR, THE TIME  OF  WEEK,
 OR TIME OF  DAY THAT THE NOISE FROM AIRCRAFT OPERATIONS WOULD ANNOY
THEM OR CREATE  PROBLEMS FOR THEM?   TORRANCE, WITH THE AID OF A
 PORTABLE  NOISE MONITOR  AND LATER A SOPHISTICATED  COMPUTERIZED  SYSTEM
 WITH 11 MONITOR  SITES,  CONDUCTED A SERIES  OF NOISE ANALYSES  OF
 OPERATIONS  PRIMARILY  FROM RUNWAY 29R,

-------
     80% OF THE AIRPORT OPERATIONS OCCUR TO THE WEST,1 A SIGNIFICANT
AMOUNT OCCUR ON RUNWAY 29R,
     FROM THIS ANALYSIS WE DEVELOPED A CURVE WHICH IDENTIFIED THE
BULK OF THE AIRCRAFT OPERATING AT TORRANCE MUNICIPAL AlRPORT,
     V/E DETERMINED THAT ABOVE 82 MAXIMUM AND 88 SINGLE EVENT NOISE
EXPOSURE LEVEL, 5% OF THE AIRCRAFT FLEET WOULD BE AFFECTED,
     THE CITY COUNCIL IN INITIATING ACTION TO CONTROL THE NOISE IN
THE VICINITY OF THE AIRPORT SELECTED THESE AS THE UPPER LIMIT FOR
DAYTIME OPERATION TOGETHER WITH 76 MAXIMUM AND 82 SINGLE EVENT AS
THE NIGHTTIME LIMITS,
     THESE LIMITS WERE SELECTED BASED ON AN ANALYSIS OF AIRCRAFT
MIX AND THEIR  IMPACT ON THE COMMUNITY,  OUR SELECTION AND DECISION
APPEAR TO HAVE BEEN JUSTIFIED  IN VIEW OF THE COURT DECISION  IN
SANTA MONICA,
     ONCE THE  INFORMATION, IDENTIFICATION OF THE PROBLEM, AND POSSIBLE
SOLUTIONS ARE  ASSEMBLED, THE THIRD EFFORT AT REMEDIAL MEASURES MUST
BE  INITIATED,
     THERE MUST BE AN  EDUCATION  PROGRAM FOR BOTH PILOT USERS AND  THE
COMMUNITY,
     WHEN  YOU  TALK ABOUT  EDUCATION, MOST  PILOTS  SAY  "No WAY", AND
MOST COMMUNITY REPRESENTATIVES SAY  "YOU'VE  GOT TO BE KIDDING",
     PILOTS  RESENT THE  IMPLICATION  THAT THEY ARE LESS THAN  COMPETENT
 IN  THEIR  TECHNICAL SKILL, AND  THE COMMUNITY DOES NOT BELIEVE THAT
THE PEOPLE  THUNDERING  OVERHEAD AND  MAKING  NOISE  CAN  EVER  BE EDUCATED,
      NONETHELESS, WE  HAVE ATTEMPTED  IT, AND WE HAVE  BEEN  REASONABLY
 SUCCESSFUL - A MONTHLY NEWSLETTER,  PROVISIONS  FOR OPERATIONAL
 EVALUATION OF  AIRCRAFT TO DETERMINE NOISE LEVEL, AND, MOST IMPORTANT
 OF  ALL,  COMMUNICATIONS',.
                                 -5-

-------
     THE MONTHLY NEWSLETTER IS SENT TO BOTH PILOTS AND THE
COMMUNITY WHO WISH TO RECEIVE IT,   IN THIS NEWSLETTER WE REPORT
ON THE CURRENT STATUS OF THE NOISE ABATEMENT PROGRAM/ NEW TECHNIQUES
FOR REDUCING NOISE IMPACT,  BOTH FROM THE SOURCE AND FLYING TECHNIQUE/
CAUTION ON TIME OF OCCURRENCE/ AND FREQUENCY OF OCCURRENCE,
     WITH EVALUATIONS/ THE ClTY HAS UTILIZED THE NEWLY ACQUIRED AND
INSTALLED NOISE MONITORING SYSTEM TO REVIEW AIRCRAFT PERFORMANCE AND
FLIGHT TECHNIQUES/ WE CAN TALK DIRECTLY TO THE PILOTS THROUGH OUR OWN
MULTI-COMM FREQUENCY ACQUIRED FROM THE FCC FOR NOISE ABATEMENT PURPOSES,
     A PILOT CAN MAKE 2 OR 3 RUNS USING DIFFERENT TECHNIQUES AND GET
INSTANT ANSWERS ON WHICH TECHNIQUE IS MOST EFFECTIVE IN REDUCING NOISE
FROM HIS AIRCRAFT OPERATION,
     THE GREAT MAJORITY OF THE PILOTS ARE COOPERATIVE AND UNDERSTANDING
IN RESPONSE TO THE EDUCATION PROGRAM,  PILOTS PRIDE THEMSELVES IN THE
PROFESSIONAL EXECUTION OF THEIR SKILL,
     THE EDUCATION PROGRAM  IS ALSO AN EXCELLENT TOOL FOR COMMUNICATING
WITH THE COMMUNITY WHAT IS BEING DONE/ WHAT IS NOT BEING DONE/ AND_WHY,
     EDUCATION  is VOLUNTARY  AND ONLY GOES so FAR,
     THE FOURTH  ELEMENT IN  REMEDIAL MEASURES IS ENFORCEMENT,  THE ClTY
COUNCIL OF TORRANCE/  BASED  ON DATA GATHERED/ ANALYSIS/ AND EVALUATION
OF THE AIRPORT  NOISE  ENVIRONMENT/ ADOPTED AN ORDINANCE AND SUBMITTED
 IT TO THE FEDERAL AVIATION  ADMINISTRATION,
     THE CITY  RECEIVED APPROVAL OF CERTAIN  PROVISIONS  IN THAT ORDINANCE/
THE  LIMITATION  ON TIME  PERIODS WHEN TOUCH AND GO  TRAINING  OPERATIONS
COULD BE  PERFORMED/  AND THE  INSTITUTION OF  A DEPARTURE CURFEW,
      ENFORCEMENT OF  THESE  PROVISIONS  COMMENCED  IN OCTOBER/ 1978,  A
 SERIES  OF CITATIONS  WERE  ISSUED OR COMPLAINTS FILED; THE  INCIDENTS  OF
 VIOLATION OF  THESE  PORTIONS OF THE ORDINANCE ARE  NOW ZERO,
                                 -6-

-------
     INITIALLY THE LOCAL FEDERAL AVIATION ADMINISTRATION MADE
MINIMAL COOPERATIVE EFFORT IN THE ClTY's ENFORCEMENT OF TOUCH AND
GO LIMITATIONS AND DEPARTURE CURFEWS,  AFTER SOME DISCUSSION THE
FEDERAL AVIATION ADMINISTRATION NOW ISSUES ADVISORIES FOR THE PURPOSE
OF ASSISTING PILOTS WHO MAY BE UNAWARE OF THE LIMITATIONS,  ADVISORIES
SUCH AS "FOR NOISE ABATEMENT, REQUEST You MAKE A FULL STOP" IN RESPONSE
TO A REQUEST FOR TOUCH AND GO DURING PROHIBITED HOURS,
     THIS HAS BEEN MOST HELPFUL IN PREVENTING PILOTS FROM BEING CITED
AND CALLED INTO COURT AND FINED,
     OUR OBJECTIVE, AFTER ALL, IS TO REDUCE THE NOISE IMPACT, NOT TO
COLLECT FINES OR CITE FOR MISDEMEANOR VIOLATIONS,
     THE CITY OF TORRANCE PLANS TO EXPAND ITS ENFORCEMENT ACTIVITIES
INTO THE MAXIMUM NOISE LEVEL PORTION OF THE ORDINANCE BASED ON THE
DECISION IN THE SANTA MONICA CASE,
     THIS WILL  IMPACT THOSE PILOTS WHO HAVE SELECTED AN AIRCRAFT THAT
CANNOT MEET THE NOISE STANDARDS AT TORRANCE OR THOSE PILOTS WHO DO
NOT OR WILL NOT UTILIZE THE TESTED AND PROVEN TECHNIQUES FOR REDUCING
NOISE FROM THEIR AIRCRAFT OPERATIONS,
     AGAIN, THE PURPOSE is NOT TO FINE AND NOT TO CITE, BUT TO REDUCE
NOISE,
     PILOTS AND AIRCRAFT OWNERS WHO MEET THE NOISE LIMITATIONS AT
TORRANCE ARE BENEFITED BY THIS ENFORCEMENT,  IT REDUCES THE AMOUNT OF
OVERALL NOISE  IMPACT AND REDUCES THE PRESSURE FOR ADDITIONAL LIMITATIONS
ON THE AIRPORT  AND  ITS OPERATIONS THUS MAKING THIS MODE OF TRANSPORTATION
AVAILABLE TO THE MAJORITY OF  USERS,
     THE FIFTH  MOST  IMPORTANT  REMEDIAL MEASURE  IS REPORT THE RESULTS,
 IN THE FOUR PREVIOUS STEPS, REPORTING THE STEPS AND THEIR RESULTS  IS
THE MOST IMPORTANT  OUTGROWTH  AND SUPPORT THAT CAN BE  USED,
     A FULL DISCLOSURE OF  INFORMATION, GOOD OR  BAD, ON  THE RESULTS OF
THE OVERALL NOISE  ABATEMENT  PROGRAM  IS  IMPORTANT  IN OBTAINING
                                -7-

-------
CREDIBILITY AND SUPPORT OF BOTH PILOTS AND COMMUNITY,
     THE NEWSLETTER,  PRESENTATIONS TO GROUPS,  SERVICE  CLUBS,  AND
ORGANIZATIONS OF THE  NOISE ABATEMENT PROGRAM'S FUNCTIONS AND  OBJECTIVES,
INTERFACE WITH MEDIA  TO KEEP THEM ADVISED AS TO THE PROGRESS  - ALL
ARE IMPORTANT TO A SUCCESSFUL PROGRAM,
     THE FEDERAL AVIATION ADMINISTRATION'S AVIATION NOISE ABATEMENT
POLICY, PUBLISHED IN  NOVEMBER, 1976, FURNISHES A BASIC GUIDELINE FOR
NOISE REDUCTION PROGRAMS,  A REASONABLE PROGRAM, BASED ON PROPER
ANALYSIS, EVALUATION, AND PREPARATION, CAN BE ASSURED  OF A REASONABLE
RESPONSE FROM THE FAA,
     UNFORTUNATELY, THERE ARE SOME ELEMENTS IN ANY GIVEN PROGRAM THAT,
FROM TIME TO TIME, RECEIVES A NEGATIVE RESPONSE FROM THE FEDERAL
AVIATION ADMINISTRATION BASED ON NATIONAL POLICY,
     THE FEDERAL AVIATION ADMINISTRATION'S STRICT ADHERANCE TO NATIONAL
POLICY  IN CERTAIN MATTERS IS UNRESPONSIVE AND NEGATIVE IN ITS IMPACT
ON LOCAL COMMUNITIES, AGENCIES, AND AIRPORT PROPRIETORS WHO NEEO ALL
THE HELP THEY CAN GET TO MAINTAIN THE TERMINAL ELEMENT OF OUR AIR
TRANSPORTATION SYSTEM,
     THE SUCCESS OF REMEDIAL MEASURES BY THE CITY OF TORRANCE AND
OTHER GENERAL AVIATION AIRPORT PROPRIETORS WOULD BE MUCH MORE PRODUCTIVE
IF THE  FEDERAL AVIATION ADMINISTRATION WAS MORE RESPONSIVE AT THE LOCAL
LEVEL PERMITTING THE REGIONAL OFFICES MORE FLEXIBILITY WITH GENERAL
AVIATION AIRPORTS, THEIR NEEDS AND REQUIREMENTS,
     THIS WILL LEAD TO A POLICY WHICH CAN REFLECT POSITIVE NOISE
ABATEMENT EFFORTS DESIGNED SPECIFICALLY FOR LOCAL GENERAL AVIATION,
     IN SUMMARY, A CASE STUDY OF REMEDIAL MEASURES AT TORRANCE
MUNICIPAL AIRPORT  INCLUDES LAND USE CONTROLS BY REDEVELOPMENT AND
                                -8-

-------
REUSE, DEED RESTRICTIONS,  AVIGATION EASEMENTS,  AND ACOUSTIC
CONSTRUCTION REQUIREMENTS  TO PROTECT THE AIRPORT AMD THE COMMUNITY,
     IT INCLUDES COMMITMENT OF RESOURCES TO A PROGRAM,
     WITHOUT THIS COMMITMENT OF DOLLARS AND PEOPLE, ANY PROGRAM is
ONLY PAPER, ORDINANCES, LAWS, CODES, AND IT WILL BE A "PAPER TIGER",
     THE PROGRAM INVOLVES  ANALYSIS OF AND DEFINING THE PROBLEMS,
MORE RESOURCES, DOLLARS, PEOPLE AND EQUIPMENT,
     THE PROGRAM INVOLVES  EDUCATION FOR THOSE WHO CAN DO SOMETHING
ABOUT THE PROBLEM, THE PILOTS AND THE COMMUNITY, MORE DOLLARS AND
RESOURCES,
     THE PROGRAM INVOLVES  ENFORCEMENT,  SOME REQUIRE GREATER INCENTIVE
THAN OTHERS TO TAKE POSITIVE STEPS TO DO SOMETHING ABOUT THE PROBLEM,
MORE DOLLARS AND PEOPLE,
     AND FINALLY, REPORTING THE RESULTS OF THE PROGRAM TO THE COMMUNITY
AND PILOTS,
     USE OF THE NEWSLETTER, PERIODIC REPORTS TO THE CITIZENS' ADVISORY
COMMITTEE, AIRPORT COMMISSION, AND CITY COUNCIL KEEP THE PILOTS AND
COMMUNITY  INFORMED OF  PROGRESS,
     WITH THESE REMEDIAL MEASURES, TORRANCE HAS REDUCED THE AIRPORT
NOISE CONTOURS, ACCOMODATED A  SLIGHT  INCREASE  IN OPERATIONS, GAINED
A SIGNIFICANT  INCREASE  IN REVENUES, AND WE HAVE NO MORE DEMONSTRATIONS
AND PROTESTS  IN FRONT  OF ClTY  COUNCIL,
      IT'S WORKED FOR TORRANCE,
     WE THINK  IT'S A MODEL  PROGRM,
     THANK YOU,

   REMEDIAL MEASURES FOR DEALING WITH NOISE ASSOCIATED
              WITH GENERAL AVIATION ACTIVITY

                            By
                 LEWIS S. GOODFRIEND, P.E.
             Lewis S. Goodfriend & Associates
                 Cedar Knolls, New Jersey
To provide relief from noise problems at a General Aviation
Airpcrt, or to eliminate such problems, requires the identification
of the specific problems at that airport, and the development
of an integrated plan for remediation.  This paper first
examines the nature of the GA Airport noise problem, and
then outlines what remedies are available and how they may
be synthesized into a noise impact control system.

The first step in remediation is the identification of the
nature of the existing noise impact, and of the portion of
the surrounding community for which the noise problem exists.
This first step may, in itself, be the major one in remediation
since conventional noise impact descriptors have not appeared
to be suitable for GA Airport noise assessment  '  .  Among
the problems in appl/ing noise descriptors are:
          Different operations at the same level cause
          difference responses.

          Flight tracks vary widely for the same category of
          aircraft at typical measuring locations, thus
          yielding a large spread in measured  levels.

          Community response appears to occur  as a complex
          function of flight frequency, maximum level,
          duration above ambient, and visibility.

-------
This has been confirmed to some extent by Harris in his
study for the Massachusetts Aeronautics Commission, and by
some work performed by my own associates at Morristown
Municipal and other nearby airports.

In one case, the noise complaints occur only when aircraft
land at night with their lights on before they cress the
airport property fence.  The average daily traffic at this
airport is only about four movements a day.

A qucte from Harris further delineates the nature of the
problem of using noise desc-riptors in defining and remedying
GA Airport noise problems,

          - ...cumulative aircraft noise near the ambient
            for other noise resulted in concerted community
            action.

     These airports were all in relatively quiet areas.
     Serious complaints and concerted community action
     occurred with aircraft noise levels in the range from
     L,  50 to L,  55, levels far below current official
      dn        dn
     standards of acceptability.

              airport neighbors first complained about  levels
              of noise exposure from touch-and-go  training
              operations about 5 dB lower  than  they  first
              complained about levels of noise  exposure
              from normal arrivals  and departures.

     Complaints for normal operations started when the
     levels of exposure exceeded L,   55.   We traced  most of
     the complaints at the small general aviation  airports
     to the frequent  touch-and-go training flights.
                            -2-

-------
     Complaints about touch-and-go flights did not occur
     when the levels of exposure due to a touch-and-go
     flights were below L,  50;  however, they occvirred on a
     regular basis when exposure exceeded L,  50.   At the
     airports we studied, there were no levels due to touch-
     and-go flights that exceeded L,  55.

It is probable that a careful record of community complaints
is the best indicator of GA Airport noise problems.  Serious
noise problems can te monitored using conventional level
monitoring equipment.  But the use of such data to predict
impact can again best be done for the specific runway on the
basis of local community noise response information.

In order to relate airport operations to noise impact,
detailed information on the individual GA Airports is necessary,
Information includes:

     1.   Size.

     2.   Physical relationship of airport and noise-sensitive
          areas.

     3.   Traffic volume.

     4.   Traffic mix  (prop only).

     5.   Presence of  jet traffic.

     6.   Frequency  of  jet traffic.

     7.   Fixed base activities  (static engine run ups).

     8'.   Runway  use.
                             -3-

-------
With this information and the complaint records,  it may be
possible, without any acoustical information at all, to
estimate the noise impact on surrounding areas.  Add to
these data tiie ambient noise levels in the area,  and the
actual or predicted maximum levels at the noise-sensitive
locations due to aircraft operations, and the problem will
almost define itself.

Experience at a number of snail airports has confirmed
Harris1  findings with regard to touch-and-go traffic noise.
If the neighbors hear it for the better part of any hour it
will cause complaints.  Furthermore, frequent departing
flights  with noise levels significantly above the ambient,
cause complaints.  With respect to jet traffic, it  appears
that there is no simple relationship between frequency of
flights  and annoyance.  The communiry response appears to
occur in three discrete steps:

     1.   Awareness of jet traffic.

     2.   Annoyance by jet traffic.

     3.   Group action against  jet flights.

It  is clear from this preliminary discussion,  that  there  are
few functional relationships to guide  us  in  the assessment
of  the  impact of GA Airport noise  in the  surrounding  community,
However, the remedial measures  available  are also  discrete
in  nature,  so that we are not  faced  with  measuring  a  small
change  in noise  level or impact.   If we can't  make  a  change
equivalent  to a  five  or  10 decibel  reduction in  level,  we
will see no change in the community  response.
                           -4-

-------
There are several generic types of remedial measures.   These
include political, regulatory,  operational, economic,  and
community relations measures.  Some remedial measures  are
accomplished through a combination of those elements listed.
Political solutions are those which result from actions by
municipal bodies such as the governing body or the planning
board.  Actions which deal with the zoning of properties
around the airport on the basis of a long term local or
regional plan are examples.  Such political solutions  are
.'jeldon feasible today because master plans have been adopted,
and changing them may create hardships and inequities that
result in litigation.  A partial solution is the purchase of
properties that are, or will be, impacted by airport traffic.
But, even such land purchase can lead to litigation.  However,
land use planning is a continuing process and must continue
to be a major element in individual airport planning.   Other
political remedies involve landing fees, hanger rental, and
the rate of development of the airport in view of its attractiveness
to both based and itinerant  aircraft.

Regulatory measures include  those activities which are under
the control of the airport management.  These include noise
limits at monitoring locations and the use of curfews on
aircraft not meeting published noise level standards.  This
is, in essence,  the use of a maximum single event noise
level.

The operational  measures available to  the  airport operator
include  the publication  and  use  of a preferential runway
system,  the use  of noise abatement flight  procedures,  and
the identification for pilots  of noise-sensitive areas.
                             -5-

-------
Of course, for single runway airports,  the preferential
runway idea isn't much help.  However,  flexibility in the
assignment of departure headings, and close cooperation
between FAA tower personnel and the airport management, can
reduce the impact during high density traffic periods.

For smaller airports, touch-and-go traffic may all occur
near or over residential areas.  It is here that attention
needs to be given to the place of flight training in the
airport community relationship.  It may be that airport
operators will have to decide whether business traffic and
aircraft maintenance activities are more important than
flight training and hanger or tie-down income.  It has
occurred to many in the general aviation area, that some
trade offs in this area may be in order.  Just turn on your
radio on some clear Friday afternoon and listen to the
combination of student pilots, business twins, and high
performance jets all in the same traffic pattern.

A  combination of regulatory and operational measures  has
been adopted by some airports, which require  the  filing of
applications by those wishing  to operate  turbine-powered
aircraft  into the airport,  end which also  require that
certain procedures be followed during  landing and takeoff.
These procedures are published in  some cases  as Jeppesen-
like pages.

Economic  remedial measures  include incentives for major
corporations to maintain  a  good  neichbor  image by minimizing
their fleet  impact on the neighboring  community.   This
provides  strong motivation to  operate  quietly and to upgrade
the flight with quieter aircraft.
                           -6-

-------
Another economic aspect of remediation exists when the
impacted community includes members of the owning companies'
staffs.

At some airports, the management works closely with the
neighboring communities to pinpoint those operations that
appear to have the greatest impact, and with the cooperation
of the FAA personnel implement noise abatement plans.  Also,
corporate pilots have joined together in formal organizations
at some airports and, among other activities/ work toward
nois« abatement and improved community relations.  This may
include assessment of operational procedures for noise
abatement involving turbine-powered equipment noise, as well
as participating in community activities.  It has been known
for many years, that noise annoyance is increased by the
belief on the part of the auditor that the noise is unnecessary
or can be easily abated.  It is also known that good community
relations is worth up to 10 dB of noise reduction.  With
this in mind, it is clearly important for airport managers
to work at improving community relations.  Programs which
identify communications paths for complaints, follow-up
reports on complaints, and disseminate information on studies,
programs, and actions taken to improve the noise situation
are very important.  This means not issuing press releases,
but meeting with elected officials of neighboring municipalities
and community groups and bringing in the pilots organizations
and FAA staff where they can hear the problem at first hand,
discuss the operational aspects, and then discuss potential
measures to reduce the noise impacts both in the near and
long term.

There are some problem areas where the ideas that have been
presented will not be easy to implement.  These  include:
                            -7-

-------
     1.    Airports in one municipality  that  are  owned  by
          another municipality.

     2.    Airports on the edge of  one municipality  that
          causes noise problems in another.

     3.    Suburban airports initiating  turbine-powered
          activity.

     4.    Airports opening new fixei base jet maintenance
          facilities.

Nevertheless, a program for remediation should always  be
available to each airport management.  It should be operating
before any complaints occur, and it may result in never
having serious noise complaints.  Such a program includes:

      1.  Preparation of topographic maps and aerial photographs
          with the expected traffic patterns overlaid.

      2.  Delineation of noise-sensitive areas.

      3.  Listing of airport telephone "information" numbers.

      4.  Availability of instructions for recording complaint
          information.

      5.  A noise coordinating committee to review operations,
          recommend noise abatement  procedures, and assess
          complaints from an operational point  of view.

      6.  Issuance of noise abatement procedures if needed.
                           -8-

-------
      7.  Regional  information and eduction programs.


      8.  Cooperation  with local  governing bodies  and planning

         boards  in order  to  achieve  long term  benefits  from

         land use  planning.


      9.  Review  of FAA  documents and environmental  requirements

         for airport  development.

                        INTRODUCTION





       The need for planning around airports has been recog-



nized as a growing environmental impact problem.  To date,



the primary emphasis for most planning has involved air



carrier airports with general aviation largely overlooked.



       A survey of general aviation airports prepared under



the National Environmental Policy Act requirements indicates



that off-airport land use planning is decidedly limited.  In



a study conducted by Bragdon for EPA, 111 completed airport



master plans were reviewed.  Only 50$ of these plans did



address off-airport land use, and in nearly all instances



the concern for land use compatibility was ignored.



       The rational management of land adjacent to airports



is essential to maximize our resources, and minimize con-



flict.  Frequently, the incompatible development of this



land results in litigation, residential displacement, and



a loss in property tax revenue.  A primary reason for the



present condition is that constituents that participate



and/or influence land use decision-making are not collec-



tively involved.  Typically there is little coordination



between the public, private and quasi-public actors asso-



ciated with airport-community related planning issues.  For



example, local governmental officials, land developers and



financial institutions very often make independent decisions



without concern for the long-range impacts.  Without collec-

-------
tive participation general aviation airport master plans
will not be adequately developed and implemented.   All role
players and constituents must be identified and participate
in general aviation airport planning to maximize effective-
ness.
       This report proposes a technique to assist local
officials in identifying and gauging the involvement of the
role players who participate, either directly or indirectly,
in the development of an airport and its adjacent land area.
The technique can serve as a guide for local decision-makers
and officials in the preparation of a noise control strategy
for their general aviation airport.
       Two matrices are used to illustrate the involvement
of the various parties in specific noise control measures.
A noise control measure is an action taken by either the public
or private sector that serves to prevent, curtail or reduce
the negative impact of general aviation noise on the communi-
ties surrounding an airport.
       The matrices distinguish party involvement during the
two primary stages of the decision-making process:  planning
and implementation.  The  first matrix represents the level
and manner of each party's involvement during the planning
stage of the noise control measure(s).  The second  matrix
represents the level and  manner of each party's involvement
during the implementation stage.   It is the combination of
these two matrices that reflect land use  related decision

-------
making.
       This report contains four sections.  The first sec-
tion lists and defines the various noise control measures
that may be available to local officials in dealing with
general aviation noise problems.  Section two identifies
the parties involved in the planning and implementation of
the noise control measures.  The extent of each party's
involvement is discussed in section three, while the final
section contains general conclusions.  A complete matrix,
which  shows the interactive process of decision making, is
contained in the Appendix.

-------
                   NOISE CONTROL MEASURES

       The noise control measures listed across the top of
each matrix are divided into two categories:   remedial and
preventive. ' Those measures oriented more towards existing
development around an airport are considered remedial;
while the measures dealing with undeveloped land are preven-
tive.  Remedial measures are typically more expensive to
carry out than preventive measures, since an existing capital
intensive facility is in place.
       The two categories are by no means mutually exclusive,
however.  For example, fee simple interest in property can
be acquired for developed as well as undeveloped land.  The
cost of using such a measure as a remedial device, however,
may be prohibitive.

                    Remedial Measures

       The measures that can be used to  correct  the problems
created by incompatible development around a general  avia-
tion airport include among others:

           (1)  Tax incentive
           (2)  Aircraft noise  reduction
           (3)  Airport operator  controls
           (4)  Fair disclosure  ordinance
           (5)  Restrictions on  private  mortgage loans
           (6)  Housing relocation  and  assistance
           (7)  Purchase leaseback
           (8)  Aviation easement

-------
       Tax incentives can be offered by local  governments



to reduce the impact of aircraft noise on the  communities



adjacent to an airport.  These incentives may  take the



form of a property tax rebate to homeowners and businesses



that install sound attenuation insulation.  The adoption



of this measure may require special legislation by the



state body legally enabling the local government to take



such action.



       Aircraft noise reduction requires the development



of new engine designs or major redesign of existing engines.



This is a long-term solution to the noise problem and will



require increased research by the federal government and



engine manufacturers.



       Certain measures can be taken in the operation of



an airport to minimize its impact on the surrounding area.



For example, the airport operator can require that during



certain times of the day, provided weather conditions are



permitting, all aircraft use a designated runway.  The



approach path for the preferred runway may allow operations



over the more sparsely developed area around the airport,



thus minimizing the impact of noise.  An operator may also



require that pilots use a steeper approach to the runway.



       Noise response monitoring is a type of airport opera-



tor control.  A special noise monitoring staff is designated



by the airport operator to receive and plot complaints of



excessive aircraft noise.  If a disproportionate share of

-------
complaints are located within a particular corridor,  the
approach and departure paths are realigned away from  these
areas.  Often the monitoring includes acquisition of  physi-
cal or acoustical airport data.
       A fair disclosure ordinance requires realtors  and
developers to notify potential real estate purchasers that
the subject property is adversely affected by aircraft
noise.  Such an ordinance requires local legislative  action.
       If money is not made available for the purchase of
homes in areas adversely impacted by noise, residential
development will be severely curtailed.  Restrictions on
private mortgage loans would accomplish this objective.
Special state legislation would more than likely be required
to carry out this measure.
       An area immediately adjacent to the end of a runway
may be so severely impacted by noise to the point where it
is uninhabitable.  In this case the airport operator will
have to purchase the property  and relocate the occupants.
Federal assistance is available to accomplish this task
through the federal Uniform Relocation Assistance Act of
1970.
       In the event it becomes necessary  for an  airport
operator to purchase a business severely  impacted by  noise
or acquire a  vacant tract of  land  immediately  adjacent  to
the airport,  they may wish  to  lease  the property to  a com-
patible tenant.  Such a  measure does generally  require  a

-------
large initial capital outlay.
       A more inexpensive alternative to the purchase of
property Is the acquisition of an avigation easement.  An
avigation easement allows the  proprietor to operate air-
craft over a particular land area under a long term agree-
ment.  The effected owner(s) receive compensation, which
represents a certain percentage of the fair market value
of the property.
                  Preventive Measures
       Measures that can be used to reduce or eliminate
the potential for incompatible development around airports
include:
          (1)  Zoning ordinance
          (2)  Subdivision regulations
          (3)  Building code
          (4)  Airport noise attenuation zone
          (5)  Capital improvements program
          (6)  Fee simple purchase
          (7)  Revolving fund purchase
          (8)  Installment-purchase
          (9)  Option
         (10)  Acquisition of the development rights
       A zoning ordinance is used to regulate land use within
a given jurisdiction.  The ordinance specifies the uses that
are permitted within designated areas or zoning districts.
These zones are delineated by the local legislative body  (I.e,
City or County Council) or an appointed board (i.e. Planning
Board) with input from the community.  The ordinance itself
is adopted by the local governing body and Is enforced by

-------
either the local building inspector or a special zoning
administrator.
       The zoning ordinance can be used to control devel-
opment around airports.   Areas adjacent to an airport can
be zoned to permit only  those uses that will not be ad-
versely affected by aircraft noise.  Beside regulating the
use of land, a zoning ordinance can legally regulate the
height, bulk and area of a permitted use.
       Subdivision regulations insure that lot layout and
design and adequate improvements are provided for new
development.  These regulations can require that vacant
land, adversely affected by aircraft noise, be subdivided
into large lots, thus discouraging dense residential devel-
opment.  The actual siting of structures on the land can
also be included in a regulation.  Local governing body
adopts subdivision regulations with input and advice from
the community and the local planning board.
       A building code prescribes the minimum standards
for the construction of structures.  This code, legally
adopted by the local governing body, is meant to guarantee
the health and safety and welfare of the community.  The
building code can require that all residential  structures
constructed within the areas impacted by aircraft noise be
insulated with sound attenuation material.  Often a  certain
sound transmission class  (STC) is specified.
       An airport noise attenuation zone combines charac-

-------
teristics of both the zoning ordinance and building code.
This measure provides for the delineation of zones  around
an airport based on the relative impact of noise on these
areas.  Minimum sound attenuation standards are then estab-
lished for the construction of new buildings within each
zone.
       A capital improvements program (CIP) is a planning
tool used by local jurisdictions to phase the installation
of needed public facilities (e.g. water and sewer lines,
roads, schools) on a priority basis.  A short-range CIP,
which usually projects needs 3-5 years into the future,
specifies what public improvements will be provided by a
given jurisdiction and when these improvements will be con-
structed.  A CIP precedes the preparation of a capital
improvements budget  (GIB).  The CIB identifies the methods
by which the improvements will be financed and the source
of the funds.  Development  follows the installation of
public improvements, such as utilities and roads.  The CIP
can serve to direct  the  expenditure of public  funds in
those geographical areas most compatible  with  airport
related  development.
       A  fee simple  purchase of property  entails the acqui-
sition of all  the  rights associated with  the  ownership  of
that  property.   Among  those rights  are mineral,  air, and
development  (as  constrained by  local  land use  regulations).
An airport  operator  may  wish to  acquire  fee  simple interest

-------
in that property around an airport most severely impacted
by aircraft noise.  This measure would guarantee maximum
control over the development of the property and insure
against incompatible development.  If the airport is still
in the planning stages, this excess property can be acquired
with the site itself.   Once the property has been acquired
the airport operator can opt to dispose of it for private
development with attached restrictive covenants, retain
ownership and maintain a buffer around the facility or
retain the property for public use (i.e. parks, maintenance
garage and storage areas ).
       The major drawback to the acquisition of fee simple
interest in property is the initial capital outlay that is
required.  One of three alternatives measures can be used
to acquire the needed property and reduce the initial capital
outlay:
           (1)  Revolving fund purchase
           (2)  Installment-purchase
           (3)  Option
       A revolving fund involves the acquisition of the
needed property one tract at a time, the preparation of
each tract for development, and the sale of the tract with
attached conditions.  The proceeds from the sale are then
used to purchase the next tract and the cycle continues
until all the land impacted by noise has been acquired and
developed in a compatible manner.
                            10

-------
       An Installation-purchase program allows  the airport
operator to acquire the property required over  time.   A
bank may provide the initial outlay to the land owner in
the form of a loan to the airport operator, who in turn
repays the bank in annual installments.
       An option conveys to its bearer the right to purchase
a particular piece of property within a specified period
of time.  An airport operator may not have the  necessary
funds to acquire all the property impacted by noise so he/
she would obtain an option on the property that cannot be
purchased immediately.  The term of an option varies with
each agreement.  If a three year option is obtained, the
bearer must either purchase the property before the end of
the term, renew the option, or relinquish his/her right to
purchase the property.  The cost of an option,  although it
varies, usually includes the property taxes and a standard
interest charge.
       Rather than purchase the entire fee simple interest
in the property adversely affected by noise, an airport
operator may wish to simply acquire the development rights
for the property.  This technique is appropriate when  the
land is being used for  farming purposes.   The  cost of  the
development rights for  a particular land  parcel equals  the
difference between the  value of that acre  at its highest
and best use and its existing value.   If  the highest and
best use was dense multi-family or commercial  development,
the cost of the development rights would  probably not  be
                             11

-------
much less than the cost of the fee simple interest in the
property.  This measure is most effective where the highest
and best use is low density residential, or if the develop-
ment rights can be sold on the open market and transferred
to another tract of land.
                             12

-------
         PARTIES INVOLVED IN NOISE CONTROL MEASURES

       Parties from both the public and private sector are
involved in planning and implementing noise control measures.
In addition to public and private actors,  the national
organizations representing actors from both sectors are also
listed on the matrices.
       A description of each party's involvement in noise
control is provided in this section.  The  descriptions are
very general and merely provide a basic understanding of
the kind of role each party assumes.  The  reader is referred
to the matrices for a more comprehensive understanding.

                      Public Sector
       Parties from all levels of the public sector are in-
volved, either directly or indirectly, in  a noise control
strategy.  Federal as well as local governments influence
the development of general aviation airports and surrounding
areas.
       The public sector parties involved in the measures
listed on the matrices include:
           (1)  Local governing body
           (2)  Local planning commission (including staff)
           (3)  Local governmental agencies
           (M)  Airport operator
           (5)  Quasi-public authorities
           (6)  Sub-state regional authorities
           (7)  State legislative body
                              13

-------
           (8)  State administrative agencies
           (9)  Federal Aviation Administration
          (10)  Environmental Protection Agency
          (11)  Housing and Urban Development
       The first five parties are most directly involved in
noise control measures.  The local governing body formulates
policies and adopts regulations (e.g. zoning ordinance and
subdivision regulations) which address the development of
land adjacent to an airport.  If the airport is operated by
a governmental agency, the governing body is ultimately
responsible for the operation of the facility.
       The planning commission generally serves in an advisory
capacity to the local governing body.  The commission reviews
zoning requests and subdivision plats and makes recommendations
to the governing body.  The staff to the commission plays a
technical role, maintaining projections of the future needs of
the community and preparing objective evaluations of land
development related issues for the commission's consideration.
       Local governmental agencies maintain existing community
facilities and services and advise the governing body on the
future location of public facilities.  A capital improvements
program, mentioned previously, coordinates the activities of
these agencies.
       The role of the airport operator will vary with the
nature of the entity responsible for the operation of the
facility.  If the airport is operated by a governmental
agency or a representative of the local government, all poll-

-------
cies dealing with noise control will generally emanate from
the local governing body.  However, in the event an authority
is created to oversee the construction, maintenance and
operation of the airport, a board of directors (appointed by
the local governing body) will formulate noise control policy.
       A quasi-public authority can also influence develop-
ment around an airport.  The independent nature of authorities
permits them to function outside the political process, once
established.  This independence creates a coordination problem,
Each authority, whether it administers a water or a school
system, can influence the direction and intensity of growth.
Their activities must, therefore, be coordinated with those
of the local governmental agencies if a comprehensive approach
to development is to succeed.
       Sub-state regional agencies generally serve a review
function.  This power (as granted through the Federal A-95
review process) permits these agencies to review and comment
on plans which have some regional impact and entail the ex-
penditure of federal funds (e.g. airport planning and con-
struction) .
       The state legislative body passes enabling legislation
that grants specific powers to municipalities and authorities.
If a municipality wished to offer special tax incentives to
guarantee compatible development around an airport, for
example, special state legislation would more than likely be
required.
                              15

-------
       In some cases the state department of transportation
(DOT) provides grants for airport planning and construction.
In Georgia, for example, the state DOT provides for 10% of
the cost of the following items:
          (1)  Master plan preparation
          (2)  Runway construction and lighting installation
          (3)  Various costs such as utility extension
       The federal government plays a significant role in air-
port planning and development.  The Federal Airport Trust Fund,
administered by the Federal Aviation Administration (FAA),
provides airport planning and construction grants on an 80-20
match basis.  Among the uses to which these grants can be put
is the purchase of land adversely impacted by noise.  The FAA
also formulates federal policy dealing with airport noise
control.
       The EPA, through the Administrator is responsible for
coordinating all federal noise efforts.  Although EPA does
have legal authority to propose regulations for controlling
and abating aircraft noise the FAA, after consultation with
EPA and the Secretary of Transportation, is responsible for
prescribing and amending aircraft standards and regulations.
       The Federal Housing Administration (FHA) and Veterans
Administration (VA) insure home mortgages.  The FHA, for
example, has a policy of not insuring mortgages on homes
located in the zone around an airport most severely impacted
by aircraft noise.  Less impacted impacted areas can receive
mortgage approval only when certain controls  are instituted
                              16

-------
(e.g. acoustical treatment of structure).   Both of these
programs are associated with the U.S.  Housing and Urban
Development.

                     Private Sector
       The private sector parties involved in planning and
implementing the measures listed on the matrices include:
          (1)  Fixed base operator
          (2)  Property owners
          (3)  Neighborhood organizations
          (4)  Environmental groups
          (5)  Local chamber of commerce
          (6)  Real estate firms
          (7)  Private developers
          (8)  Private contractors and builders
          (9)  Private lending institutions
         (10)  Aircraft engine manufacturing firms
         (11)  Planning and environmental consultants
       A fixed base operator leases an airport terminal from
a municipal or county government and maintains and operates
the facility.  Under these circumstances, the ultimate
responsibility for airport policy lies with the local govern-
ing body.
       Individuals who own property around an airport can
have opposing interests in airport operations.  A residential
property owner may oppose airport operations if aircraft
noise decreases their property values and disturbs them
personally.  Another property owner may, however, possess a
vacant tract of land that is large enough to be developed
                              17

-------
industrially (or in some other compatible manner).   This
owner would, therefore, welcome airport expansion.
       Neighborhood organizations consist of property owners
and renters.  If enough members of a particular organization
are adversely affected by aircraft noise, the organization
may well take a stand against airport operations.   An environ-
mental group would represent the interests of those citizens
adversely affected by noise.
       The local chamber of commerce consists of local busi-
nessmen and is concerned with the economic growth of the
community.  An airport can stimulate or enhance the economy
of an area.  Therefore, the Chamber of Commerce would tend
to espouse the economic virtues of airport operations.
       The development of land around an airport involves
the participation of developers, lending institutions, con-
tractors and builders, and real estate firms.  The developer
"packages" the development and obtains financing from a lend-
ing institution.  "Packaging" a development often entails
preparing a market analysis and project feasibility study and
in some cases, acquiring the necessary property.  The con-
tractors and builders, as well as the developer, may be in-
volved in the actual construction of the project.  A real
estate firm then sells the project.
       Aircraft engine manufacturing firms are concerned with
producing engines that provide for the safe and efficient
operation of aircraft.  Recent federal legislation requires

                             18

-------
that engines manufactured meet certain noise standards.   As
a result, engine manufacturing firms have a vested interest
in noise control strategies for airports.
       Consultants play an advisory role in planning and
implementing noise control measures.  Planning and environ-
mental consultants sometimes assist in the preparation of
airport compatibility studies.  These firms can also serve
in an advocacy position, representing the interests of a
local community.

                  National Associations

       There are several national associations which repre-
sent the interests of the various role players involved in
airport noise and land use compatibility planning  (see Appen-
dix A).  Most of the associations simply provide a forum
where their members can express opinions on particular issues
Some of the associations are  sufficiently large and they  can
exert political pressure on and influence the decisions of
local, state and federal legislative  and policy making offi-
cials.  All of the associations listed in the appendix have
roles to play in planning and implementing  certain noise
control measures.
       The  associations are divided into ten  categories:

            (1)  Associations  for aircraft operators
            (2)  Associations  for airport operators
            (3)  Manufacturing related associations
            (4)  Associations  dealing with airport  services
            (5)  Associations  related to  airport safety
                              19

-------
           (6)  Other aviation-related associations
           (7)  Environmental associations
           (8)  Real estate and development associations
           (9)  Banking associations
          (10)  Other relevant national associations
       The associations represented in each category, due
to a common interest, assume similar roles in the planning
and implementation of noise control measures.  The first
six categories deal directly with aviation concerns.  Asso-
ciations for aircraft operators represent the interests of
aircraft pilots and owners.  One of the largest and most
influential aviation associations, the Aircraft Owners and
Pilots Association (AOPA), falls within this category.
       The associations in category two represent airport
operators.  The third category includes associations which
represent firms that produce and/or distribute aviation
products (i.e. aircraft, aircraft engines, electronic de-
vices , etc.).
       The members of the associations in the fourth category
rely on airports for their livelihood.  Any disruption in
the operation of an airport may affect the financial status
of the members in this category.  The last two aviation
categories deal with flight safety and the overall develop-
ment of the aviation industry, respectively.
       The next three categories contain associations that
represent specific airport noise and land development in-
terests of communities around airports that are adversely
                             20

-------
affected by noise.   The real estate and banking associations



represent the respective interests of these two parties and,



in some cases, influence the land development and lending



practices and policies of association members.
                             21

-------
             THE EXTENT OF PARTY INVOLVEMENT
                IN NOISE CONTROL MEASURES

       Knowledge of the noise control measures  and the par-
ties involved in those measures is a necessary  prerequisite
to the preparation of an effective noise control strategy.
An understanding of the extent of the parties involvement
is equally important, however, as it allows the officials
devising a strategy to assess its impact and incorporate the
input of these parties affected into any final  plan or pro-
posal.
       Two indicators are used in the matrices  to assess the
extent of a party's involvement in a particular noise con-
trol measure:  (1) the level of involvement and, (2) the
manner of involvement.
                  Level of Involvement
       A party is involved in a noise control measure on one
of two levels:  direct or indirect.  The characteristics of
each level are represented in Tab^e 1.
       Scale is the crucial distinguishing factor between
direct and indirect involvement.  The remaining character-
istics are byproducts of scale.  Those parties that operate
at the local level and have an ongoing role in the local
decision-making process will be more directly involved in
planning and implementing noise control measures.  Private
as well as public parties are involved at this level.  On
                              22

-------
the other hand,  those governmental administrative agencies
and private organizations removed from the local scene
have only an indirect influence on the local decision-
making process.
       The higher the level of involvement the more time
consuming and complex the decision-making process will be.
For example, a zoning ordinance will only require decisions
at the local level, whereas the purchase of fee simple
interest in land will more than likely require federal and,
in some cases, state funding.  The inclusion of these two
additional levels will involve more time and several more

parties.

                  Manner of Involvement

       Three parameters are used to distinguish the manner
of a party's involvement in planning and implementing a
noise control measure:

            (1)  The party serves in an advisory capacity
            (2)  The party has an economic stake in the
                measure, and
            (3)  The party is involved in an administrative,
                legislative or policy formulation manner.

       The parties that approach the measure  objectively,
seeking to advise the decision-makers, function  in an
advisory capacity.  Under certain  circumstances, the  role
of the adviser will change from  one stage of  the process
to the next.  For example, while the planning commission

-------
and staff may serve in an advisory capacity during the



planning stage of a zoning ordinance,  once the ordinance



is adopted, the role of the staff becomes administrative.



       The input of a party with an economic stake in a



measure will tend to be subjective.  If, for example, a



proposed airport zoning ordinance will restrict a property



owner from developing his land beyond two units per acre



when the market could bear a multi-family development, the



property owner would have an economic stake in the matter



and, therefore, assume a subjective position.



       Governing bodies (including local and state bodies),



administrative officials and boards, and airport operators



comprise the group of parties involved in noise control



measures in an administrative, legislative and policy for-



mulation manner.  Administrative and legislative tasks are,



in most cases, carried out by local elected and appointed



officials.  Policy formulation is carried out by these offi-



cials, as well as state and federal agencies.



       The manner of a party's involvement sometimes varies



depending on when he is involved in the decision-making



process.  If, for example, a quasi-public authority has



sold bonds for a public improvement on the assumption that



dense development will follow, it will more than likely take



a stand against land use controls requiring low density



residential development or agricultural use.  The authority's



primary concern is with protecting the interests of  its



bondholders.
                             25

-------
                     CONCLUDING REMARKS







       The matrices discussed in this report provide some



guidance to local officials in both the identification



of the parties involved and, the assessment of the extent



of the parties involvement, in carrying out selected noise



control measures.  These matrices serve only as references,



however.  The problems associated with coordinating the



involvement of the parties is a complex process that will



vary with each local situation.  The measures chosen to deal



with the problem will also vary, depending on such factors



as:  (1) the number of jurisdictions affected, (2) the avail-



ability of funds, and (3) the type of land uses affected.



       It is essential that local officials perceive the



scope of the general aviation noise problem and identify



and involve all affected parties in the search for an appro-



priate noise control strategy.  Such advance planning will



result in the effective and rational management of land



adjacent to general aviation airports, while minimizing



the potential conflict between the many parties involved.

           A  Case for
    Single-Event Intrusion
     Criteria in Achieving
Noise-Compatible Land Use
  In the lasi few years, the acoustics com-
munity has made great stndes towards
adoption of a single composite mctnc of
noise  source emissions  the day-night
sound level (LrtJ  These efforts, largely
through the support of the US Environmen
tal Protection Agency,  nave led to rather
refined transportation  noise  prediction
models for  aif:af'  operations, highways
and freeways find railroad operations Al-
though the quantification of a source's ' av-
erage day'  noise emission in terms of LAn
can provide a useful oasis for establishing
noibe-compntibl'i.' und use guidelines, there
is a clear .-,ccd for supplemental information
on the intrusive charactcnsrtcs of a particu-
lar noise source if  the  actual impact  on
people s lifestyles is  to be recognized This
supplemental information  must include
identification of the  maximum A-weightcd
levels of frequently occunnq single events
(that  is truck pas*-bus aircraft  flyovers
train u-histles. and so <->n) for both day and
nighttime pcnods because, specifically it is
lh«« single-event intrusions that disrupt class-
roonib. interfere with speech, and
awaken people at night
  To assess the relative intrusiveness of
single events, such factors as the ambient
noise environment and the nature of the
proposed land use (with particular empha-
sis on the degree of outdoor space utiliza-
tion that is planned) should be considered
De-term1 nation of whether a given land use
will be compatible with  its noise environ-
ment must obviously take in many factors
which are not adequately descnbed by a
single L,,n  value  With increasing pressure
for new residential developments  adminis-
trators cannot simply take a safe, conserva-
tive approach £nd restnct residential use to
areas where exposure is less than Lrtn 55. 01
60. 01  6!>. or in some cases. Ldn 70 dB1
  In California an additional problem with
the use of /..,„ for land use controls exists
'Actually California uses the Community
Noise Equivalent Level. CNEL. which gen-
erally equals Lrtn ±  1 dB ) California law
restricts residential development around
airports above L,,,, 65 and imposes other
limitations for developments adjacent to
freeways railroads and other noise sources
where noise intrusion exceeds L,,,, 60 The
problem that arise:, is  that from a  legal
standpoint, a noise contour is considered to
ix' a clear-cut line of demarcation perma-
nenllv etched on a mop In some cases.
interpretation of noise contours has been
earned to the extreme of allowing building
on one side of a street and not on the other
buch interpretations fail to consider the in-
herent inaccuracies in noise prediction  and
the daily and seasonal vanations in noise
source activity  Hence, it is  necessary to
think of an Lrtn value as reflective of a band
of noise on the order of i  5  dB of tlie
nominal predicted (or  monitored) value
The achievement of highly accurate noise
contours, though desirable fiom a  legal
viewpoint does Imle to resolve  the funda-
mental question 'How will noise impact the
lifestyles of future residents7
  The need for inclusion of single-event
cntena in achieving noise-compatible land
use is illustrated by the following two exam-
ples of noise environments of vastly differ-
ing charactenstics
  Noise emission values 50 rn from a busy
freeway have been monitored  at 70 L,i,,
The charactenstics of the freeway noise may
be generally descnbcd as a dull roar at an
almost constant level of 70 dB(A) over most
of the day. although truck pass-bys occa-
sionally register 75 to 80 dB(A) At nigh:
levels typically drop 5 to 10 dB(A)  Now
contrast the freeway with a site 4000 m from
touchdown at a military airbase  The L,,n
value is again in the range of 65 to 70 dB.
however, in this case, there are extended
penods when aircraft noise is not audible
and the background level falls to 40 to 50
dB(A) When aircraft flyovers occur  they
produce levels of 85 to 100 dB(A) for dura-
tions of 20 to 30 seconds These flyovers
sometimes continue uninterrupted for
penods of one or two hours dunng d?y or
night, and then activity ceases  for several
hours
  Clearly,  the  noisier single-event intru-
sions in the  second example  will  affect
nearby residents more severely  than in the
first example What is suggested here is that
acoustical consultants and land use  plan-
ners recognize  the significance  of single-
event intrusions and require  that building
designs accommodate them The following
dwelling interior noise level  performance
standards have  been proposed  at selected
sites in California, m an effort to yield inte-
rior living spaces suitable for their intended
purposes  By imposing acoustic perform-
ance standards such as these, the need for
precise contour location may be greatly re-
laxed
  For any  new dwelling located m area*
exposed to noise emission in excess of Lrtn
65. mtenor noise levels in  any habitable
room must be less than or equal to Ldn 45
dB and  maximum (typically  occurring)
single-event intrusions (Lm.,x)  inside the
dwelling  shall further be limited in the fol-
lowing way

Sleeping areas    50 dB(A) — anytime
Other living areas 60 dB(A) — daytime
                 55 dB(A) — nighttime

  Often neglected however are provisions
for noise level reduction outdoors The
common practice is to beef up outdoor-to-
indoor noise insulation in residences,
thereby supposedly yielding  them compati-
ble with high noise environments Ethically,
we cannot expect people to live in "bomb
shelters   There is a need, especially in
single-family residential developments with
small children,  to  provide  outside living
areas free from excessive noise exposure
Such a requirement would  necessitate, in
the case  of an aircraft overflight situation.
some rather innovative architectural con-
siderations  Ground  level  noise sources
present much less of a design challenge —
but one that is often  overlooked nonethe-
less  A performance standard which limits
maximum  noise levels in  certain well-
defined outdoor living areas to, say, 70 to
75 dB(A) would do much to improve the
quality of living for those affected That a
clear need for such outdoor area noise in-
trusion standards exists is demonstrated by
the fact that  in southern California, both
commercial and milit?rv airports report sig-
nificantly greater numbers of noise com-
plaints Junng penods of pleasant outdoor
weather, particularly dunng the evening
time period (1900 to 2200 hours).
  The final critical  element m utilizing
single-event noise levels is that  such infor-
mation be provided to the prospective pur-
chaser m layman s terms wh.ch relate these
levels to  their potential impart on botn in-
door and outdoor activities  A prospective
purchaser of a home near an airport or a
freeway would then be advised  in advance
that  noise levels would  possibly interfere
with speech or that sleep may be impaired,
and so on The obicct of this would be to
allow people to make an informed decision
regarding the significance of noise impacts
upon their lifestyles  and to choose resi-
dences according!v It is time  to establish the
degree of acceptability  of various sites in
terms of specific cntena which relate to
people s  activities rather than in terms of
iibstrrul composite  rnelncs which strive to
lump nil  factors together for the conveni
ence of lawyers, but  ignore  their intended
purpose
