Dear Rerder:
Aircraft noire is now a significant problem tor nw.ny people living near
aiiports. Part of the solution to this problem ran be found in abatement
actions which are specific, to individual community/ airport situations.
Ad od Li on oi F.uch airport specific actions must be. preceded by tie inaJviii .
am. depiction ot both current situations and all feasible abatement
options.
Until now, the analysis of noise abatement options has often been equated
with complex and expensive computer operations, the coe'_ of which may be
beyond the capabilities of some airport proprietors, involved communities,
or local land use planners. This manual will allow one to calculate, on
an airport specific basis, the day-night average sound level (L, )
which results from civil aircraft operations and thus predict tne noise
impact in areas near the airport. This "desk, calculation" of aircraft
noise levels was adapted from the type of computer systems now in use by
both the Federal Aviation Administration and the Environmental Protection
Agency.
We at EPA believe that this manual desk calculation process is a major
step forward with respect to aviation noise abatement and compatible
land use planning.

SUMMARY
A method is described for calculating values of Day/Night
Levels	) at a point due to aircraft operations from civil
airports. Two levels of sophistication are detailed — at
the basic levelj such factors as type of takeoff and landing
procedures are considered, but: aircraft range and non-stc.ndard
approach glide slopes are excluded; the detailed method takes
account of the latter parameters. The procedure is to de-
termine distances between the point in question on the ground
and the aircraft flight tracks and runway. A series of charts
provided in the report give 7„ values for different types
of aircraft in terms of these distance parameters. An ad-
justment is made to the noise levels for each class of air-
craft to take account of the number cf operations, and these
adjustment levels are then added logarithmically to producce
an overall noise level. This method is not suitable for
generating noise contours (lines of equal	value) although
a method is described for estimating area and size of any
given contour.

CALCULATION OF DAY/NIGHT LEVELS DUE TO
CIVIL AIRCRAFT FLIGHT OPERATION
SECTION I
INTRODUCTION
This manual presents procedures and information for
calculating the day/night noise level (L^n) due to flight
operations in the vicinity of civil airports. Use of this
procedure and aircraft noise information presented in this
manual will enable you to estimate the day/night noise level
at specific ground locations resulting from aircraft takeoffs
and landings at an airport. Charts are provided in the manual
which provide noise information on most civil aircraft cur-
rently operating in the country. Noise charts are presented
for takeoff and landing operations including special noise
abatement procedures.
The basic steps in calculating day/night levels are rela-
tively simple and straightforward. However, the number of
calculations multiply by the number of types of aircraft and
the kinds of operations involved, so calculations can be quite
lengthy when calculating noise exposure near an airport where
the noise Is due to operations from several runways by a variety
of aircraft.
The handbook provides information for estimating day/night
average levels at two levels of precision:
(a)	a preliminary assessment when detailed information on
aircraft operations is not available and
(b)	a detailed assessment when accurate lnfornation on
aircraft flight operations and flight paths is known.
-1-

-------
The latter assessment requires more extensive informa-
tion on aircraft operations and may be more time consuming
to calculate.
This manual has been especially developed for desk cal-
culation cf day/night levels values at specific ground locations.
The procedures are not intended for developing noise exposure
contours around an entire airport since the calculations would
generally be too time consuming and laborious. When noise
contours over a considerable area are needed, several computer
programs are currently available and should be used.1*2* The
basic noise information provided in this manual is identical
to that used in some of the other current computer programs
for calculating day/night level contours.
This manual does not include information on military
aircraft, hence it cannot be used for calculating Ldn values
for a military airport or where military aircraft operate
from a civil airport; information on noiao from ground runup
operations is also excluded from the handbook. Noise data
are also restricted to fixed wing aircraft, so that noise
from helicopter operations cannot be calculated. However,
the basic calculation procedures can be extended to cover
those aircraft simply by providing separate noise charts for
the aircraft not covered in this manual.
This manual does not provide information on criteria,
standards or guidelines for interpreting the day/night level
*References are listed together at the end of the text.

-------
in terms of land use or community response. Such information
may be found in application guides published by various local,
state and federal agencies.
The next section of the manual provides a brief descrip-
tion of the calculation procedure. Section III describes how
to calculate L^n values at a point, and Section IV describes
a method for determining approximate L^n contours. Section V
gives additional procedures for detailed noise assessment or
non-standard flight profiles. The noise information to be
used in calculating the day/night levels is provided in
Appendix A. Appendix B provides background technical infor-
mation concerning the calculation of noise graphs and basic
modeling assumptions and sources of technical information.

-------
SECTION II
OVERVIEW
The day night average sound level (L^n) Is a measure
of the noise environment at a prescribed location over a
24-hour period. It is equivalent in terms of sound energy
to the level of a continuous A-weighted sound level with
10 dB added to the nighttime levels. The may be
measured or computed in several ways. If the noise is
monitored continuously, tne noise levels existing over the
24-hour period can be summed on an energy basis (adding
10 dB to the nighttime levels).
A second approach is adopted for calculating the L^n
values due to airport operations. In this approach, the
noise contributions from each significant aircraft operation
(takeoffs and landings) occurring over a 24-hour period are
summed on an energy basis to obtain the L^n value. In this
case, the nighttime adjustment may be introduced by either
adding 10 dB to the nighttime levels or by multiplying the
number of nighttime events by 10. This latter procedure
is the one adopted in this manual.*
To provide a systematic basis for calculations, air-
craft noise intrusions are classified by type of aircraft
and type of operations (takeoffs and landings). (The
classification for an aircraft is based on the airport
noise characteristics and its takeoff and landing capa-
bilities.) An L^n value (called a "partial" L^n) is first
*Day time is taken as the period from 7:00 a.m. to 10:00 p.m.,
nighttime is the period from 10:00 p.m. to 7:00 a.m.
-5-

-------
calculated for each claus of aircraft, taking into account
the number of significant operations occurring in the day-
time and nighttime. These "partial" L^n values are then
summed on an energy bas J s to obtain the total L, .
an
A.	Sound Exposure Level (SEL)
The noise exposure contribution frorn each aircraft
operation is described in terms of sound exposure level
(SEL). Referring to Figure 1, which shows a typical time
pattern of the noise levels existing during an aircraft
flyover, the SEL is the A-weighted sound level integrated
over the entire nci.se event and normalized to a reference
duration of 1 second. Hence the SEL gives the level of a
continuous 1 second signal which contains the same amount
of energy as the noise event. The 1 second reference dur-
ation acts like a common denominator, permitting the
addition of new events of varying durations.
Note that while the SEL is measured in terms of the
A-weighted sound level scale, the SEL is generally not equal
to the maximum A-level occurring during the noise event
(see Figure 1). Most aircraft noise intrusions last more
than 1 3ccond, so SEL value will in general be higher than
the maximum A-level for the same event.
B.	Calculation of Partial L, Values
	dn	
The L^. for one class of aircraft and mode of operation
along one flight track is called the "partial"	For
aircraft class, i, and operational mode, j, the partial L^n
(i,J) is given by:

Ldn(l,J) = SEL(i, j ) + 10 log(ND[i,J] + 10 N^[i,j])-49- 4 (1)
where = number of daytime operations
= number of nightime operations
The SEL(i,j), the firs" term in the above equation, is
dependent upon the type of aircraft, its power setting and
the distance of the aircraft from the listener at the
closest point along its flight track. The second tern of
the equation involves the number of operations for the given
type of aircraft and mode of operation. The last terra, a
constant of -49.4, reflects the normalization of Ldn to a
24-hour day, rather than to the 1 second reference value
for SEL.*
For convenient calculation, equation (1) may be re-
written as:
Ldn(iJ) = SEL( i , J ) - K(i,j)	(2)
where K = 49.4 - 10 log(ND[i,j] + 10 N^[i,j])
C. Calculation of Total L, Value
	dn	
After the partial	values are calculated for each
significant aircraft intrusion, they may be summed on an
energy basis to obtain the total- L^n due to aircraft
*The constant of 49.4 equals 10 log (number of seconds -in a
24-hour day)3 or 10 log(86, 400).

operations. Mathematically this is expressed as follows:
Close to an airport, the	contributions from air-
craft will generally be much greater than that from other
sources, hence the total L,, value due to aircraft will
equal the total L^n value for the site. At distances
further from the airport, or near other major noise sources,
the	values resulting from aircraft may not fully ac-
count for the noise exposure at the site. In such situa-
tions, noise from other sources must be taken into account
in determining the total	for that site.
D. Calculation Summary
In summary, the major steps in determining the day/
night level at any given position near the airport are as
follows:
(A)	Obtain airport and aircraft operational information to
identify types of aircraft and types of operations
that contribute to the noise environment at the de-
sired position. Also determine the distance of the
aircraft from the ground position and the number of
operations for each type of aircraft.
(B)	Determine the SEL for eaoh contributing noise event
using the noise charts given in this manual.
J
-9-

-------
(C)	Compute the partial	value for each significant class
of noise events from the SEL and number of events per
day and night.
(D)	Add all the partial	values together to obtain the
total L, for aircraft operations,
dn
The next section will describe each of the above steps
in detail with examples to illustrate applications to real
life situations.

-------
SECTION III
CALCULATION OF L. VALUES AT A POINT
dn
The basic problem to be solved is illustrated in
Figure 2 for the simple case cf a land parcel exposed to
noise from takeoffs of a single type of aircraft. To de-
termine the Lj for the land oarcel, you must be able to
dn
identify the type of aircraft, the type of operation and
the number of aircraft noise intrusions per day and per
night period. You must find out the location of the airport
runway and the flight path with respect to the land parcel.
This section describes the calculation of L , values
dn
at a single point. For small land parcels where the ex-
pected variation in noise levels throughout the land parcel
is of the order of 1 dB or less, calculations at a single
position should be sufficient. For larger parcels where
the expected variation in noise is greater than 1 dB,
calculations at several points may be needed to adequately
determine the noise exposure for the land under study.
Section V-C provides guidelines for determining whether
calculations at one or more positions are needed.
A. Acquire ?ield Information
Before starting to collect Information, a few words
of advice may be appropriate for anyone not directly con-
nected with the airport operations. In almost every case,
the best source of information is the airport manager;
either he will have the information that you want at hand,
or he can direct you to someone who has this information.
If the airport has a control tower, the FAA tower personnel
will also be a major source of information, and the airport
manager will probably pass your requests on to them.

-------
This report also suggests alternate sources of Information,
if for any reason you wish to work independently of the
airport manager.
Data acquisition involves the following six steps:
1.	Determine the physical layout of the airport runways
and the length of the runways for the flight paths
of concern.
Runway descriptions are given in FAA Form 50103 and
instrument approach prcedures published by the National
Ocean Survey and Jeppesenu'5. Many airports will also
maintain plans containing runway information, and most
airports are also shown in Coast and Geodetic Survey
(C & GS) maps. Whatever the source, a check should be
made to be sure that the airport information is current.
2.	Determine the location of the major flight tracks
over the ground and the distances D^ and Dp.
The path of the aircraft project on the ground is
called the track. This track must be located to determine
actual distances from the land parcel to the aircraft in
flight. Once the track is determined, the distances D^ and
Dp, detailed in Figures 3 and 4, should be calculated for
each track.
For takeoffs, shown in Figure 3j D^ is the distance
along the flight track from the start of the takeoff roll
to a perpendicular drawn from the flight track to the point
where the Ldn is to be determined. If the flight track is

curved, the distance must be measured along the arc of the
curve. Dn is the distance along the perpendicular drawn from
C.
the flight track to the desired position.
For landing, as shown in Figure 4, D is the distance
along the flight track from the landing threshold* to the
perpendicular drawn from the flight track through the land
parcel.	is the distance along the perpendicular from the
flight track to the ground position.
Figure 5 provides a form for tabulating the and D.,
distances. The maps and sketches which provide the basic
track information from which the and D2 distances are
determined should accompany this form.
Unfortuantely, aircraft do not fly along flight tracks
like cars along an expressway. The actual flight tracks
flown tend to fan out from the nominal flight track as the
aircraft get further from the airport. Locating the turning
point of just one aircraft will not necessarily be repre-
sentative of the mean flight track.
*The landing threshold identifies the beginning of the run-
way that is available and suitable for landings. For
most runways the landing threshold coincides with the
physical beginning of the runway. However, at some
airports the landing threshold is displaced along the
runway. This displaced threshold would be noted in the
instrument approach procedure charts but will not be
indicated on Coast and Geodetic Survey Maps.

Several sources may have to be contacted to obtain
reliable track information. Often, the best source of
information will be the FAA tower or airpor", operations
personnel. The appropriate takeoff and approach charts
from the Jeppesen Guide5 may be of some help (these charts
may be obtained individually from the publisher). Direc~
visual observation nay be needed to resolve conflicting
information, or to help determine the extent of variations
in flight track3 for different aircraft.
3. Determine the types of aircraft producing the noise
intrusions.
For convenience, aircraft; are classified into dif-
ferent aircraft types determined on the basis of their
noise characteristics and operational characteristics.
Table 1 presents the aircraft classification to be used in
this report. The table lists the general aircraft types
with specific examples. The aircraft types are listed
approximately in order of their noisiness. The aircraft
range from the 4 engine turbofan aircraft such as the
Boeing 707 and DC 8 series down to the smaller piston
engine propeller aircraft such as the Cessna 180.
Most airports will handle operations of several types
of aircraft. Start by determining'the number of aircraft
operations for each type of aircraft beginning with the
top of the list in the table. Where the number of jet
aircraft operations (transport and general aviation) exceed
more than 5% of the total operations, you need not obtain
detailed Information for the propeller aircraft operations.

H. Determine the mode of operations (Takeoff or landing)
for the aircraft producing noise instrusions.
Noise produced during takeoff and landing may differ
considerably. Similarly, the flight paths followed by
aircraft in landing and takeoff may differ significantly.
For those reasons the number of operations for each class
of aircraft must be identified by mode. If a detailed
analysis is being performed, takeoff operations must also
be broken down by trip length (see Section V-A).
5. Determine the number of operations per daytime and
per nighttime period.
The average number of operations per day should be
determined for each aircraft class and mode of operations.
For most purposes, the number of operations over a one year
period should be used as the basis for determining the
average number per day. For some detailed investigations
you may wish to consider the number of operations occur-
ring over a shorter period. For example, when pronounced
changes in aircraft operations occur during different
seasons of the year, you might, wish to calculate separate
day/night levels for the different seasons.
Determining the number of operations for each aircraft
class and mode of operation may not be easy since detailed
aircraft operational records arc not usually available.
The log 0f operations maintained by the FAA tower personnel
will provide the yearly number of air carrier, air taxi,

-------
general aviation and military operations.* However, the
FAA records do not identify the type of aircraft.
Sources of information for identifying transport
aircraft are the Official Airline Guide** (0AG) and the
flight schedules published by the individual airlines.
Some airports also provide a schedule of aircraft arrivals
and departures. And, do net neglect to check on freight
operat ions.
Discussion with the airport operator and tower
personnel will generally provide good estimates of the
number of business Jet and propeller aircraft operations.
The Information as to number of operations obtained
from different sources may be for differing time periods -
for example, dally, monthly or yearly totals. For cal-
culation purposes, this information should be corrected
to a common basis - the average number of takeoffs and
landings per day. The number of daily takeoffs and
landings should then be entered on a form (Figure 5).
* For airports having FAA towers, this information is pub
lished in "FAA Air Traffic Activity", a publication
issued by the FAA usually on both a calendar and a
fiscal year basis.

6. Determine the flight path utilization.
Track utilization is defined as the proportion of
operations in each direction along the flight track.
Takeoff direction alona; the runway may well reverse during
different periods of the day or year due to changes in
wind direction or traffic needs. Sometimes the same flight-
track will be used for aircraft departing and for air-
craft landing.* In other cases, the flight track may
differ for takeoff and landing operations. For example,
the landing track may be straight into the runway while
the takeoff nay involve a turn after liftoff.
Accurate information cn runway or flight track utili-
zation Is sometimes difficult tc obtain. This information
may be provided by the airport operator, FAA tower or
traffic personnel. Where detailed records are not avail-
able, estimates of track utilization may be obtained by
studying wind rose information (see reference 6).
Obtaining the above information completes the col-
lection of data for the basic L, calculations. The
an
information collected should be sufficient to complete
the top seven rows of the data collection and calculation
form (Figure 5)•
At this point, it is important to check that the ac-
quired information on numbers of takeoff or landings and
*Note that in this case although the same flight track is
used, the distance D^ will differ for takeoff and landing
by the length of the runway.

-------
path utilization are in the desired format. The values of
ND and to 'be entered in Figure 5 are the number of
takeoffs or approaches per day along the specified track.
Thus, if you know the total number of takeoffs of aircraft
type J per day for the airport, and the utilization of
track k, then the number of takeoffs of aircraft j on
track k is:
N(J,k) =	^
where U(J,k) = Utilization of track k by aircraft j, in
percent.
The traffic data may not be given in the desired
format, and there are certain pitfalls that are easily
fallen into. Check, for example, whether the distributions
of landings or takeoffs on each track are given as a per-
centage of all operations on that track, as a percentage
of landings or takeoffs at the airport, or as a percentage
of all opeerations at the airport. At each stage in the
calculations, it is most important to check that the total
number of operations is correct.
In general, calculating the number of operations to
two significant figures is sufficient, but do not ignore
nighttime operations Just because they may be an order of
magnitude less than daytime operations. As explained
earlier, the number of nighttime operations is multiplied
by 10 in the calculations, hence nighttime operations,
when they occur, will likely be significant.

7. Special takeoff or landing procedures.
When making a detailed ncise assessment, additional
operational information may need to be acquired.
(a)	Special noise abatement takeoffs
The basic noise charts assume ATA (Air Transport
Association) takeoff procedures for civil jet transport
operations. Special noise abatement procedures involving
reduction of engine thrust as specific altitudes nay
either be implemented at some airports or may be con-
templated as part of a noise reduction program. Information
on the procedures including the description of the pro-
cedures and the aircraft using the procedures should be
collected. Section V discusses the usage of such Infor-
mation in detail.
(b)	Special landing profiles
For basic calculations, assume a 3° glide slope
for all turbojet aircraft and the larger propeller air-
craft; for smaller propeller aircraft, assume a 4-1/2°
glide slope. For other approach angles, see Section V-B.
In some cases, a two-segment approach may be used, in which
aircraft start their approach on a 6° glide slope and then
transition tc a 3° glide slope at 2 nautical miles from
the landing threshold. These approaches have special
noise charts associated with them; these are identified in
Section III-B.

8. Data collection example (Example 1).
Two small parcels of land P and Q are the subject of
an Investigation of aircraft noise at Mythical Airport
(see Figure 6). Distances from the runway and flight
tracks are as shown, and the following operational data
have been collected:

EXAMPLE: FLIGHT TRACKS AT MYTHICAL AIRPORT

-------
The first step is tc calculate the distance and
for the points P and Q pertaining to each track. These
distances are tabulated in Figure 7.
Remember that does not have the same value for
takeoffs and landings. For takeoffs, D.^ is
measured along the track from the brake release
point, which is the point when the aircraft starts
its takeoff roll (i.e. the far end of the runway
for aircraft coming towards you). For landings,
is measured to the landing threshold which is
usually the near end of the runway, except in
the case of a displaced threshold.
The values of and D2 can be measured directly off
Figure 6, and accuracy to two significant figures is quite
adequate. In this example, both types of aircraft con-
veniently start their turn after takeoff at the same point.
More often, however, the flight; instructions would call
for a turn at a given altitude.. and since aircraft have
differing rates of climb, the turn would be initiated
at different points.
The next step is to calculte the total number of
operations at the airport broken down by type, i.e.
B-727 150 x 0.7 = 105
DC-9	150 x 0.3 = ^5
Total = 150

-------
Break these numbers down into day and night operations:
Day	Might	Total
B-727 105 x .75 = 79 105 x .25 = 26 105
DC-9	45 x .80 = 36	45 x .20 = 9 __45
150
These aircraft must be distributed on each flight
track:
Track 27A
Landing	Takeoff
Day Night	Day Nigh1;
B-727 0	0	12 3-9
DC-9	0	0	5.4 l.H
Track 27B
B-727 4.0 1.3	24 7.8
DC-9 1.8 0.5	11 2.7
Track 09A
B-727 36	12	4.0 1.3
DC-9 16	4.1	1.8 0.5
Check on total operations - 151.5
(the discrepancy here is due to rounding error)
The data has now been broken dowr. so that the L,
dn
collection and calculation chart can be completely filled
in (Figure 7)•

B. Determine the SET, for each Contributing Aircraft Noise Event
1.	Check the Distances D^ and D?
The knowledge of D-^ and of the aircraft takeoff ana
landing profile determines height of the aircraft above
ground (see Figures 3 & 4) as it passes near the ground
position. You do not have to calculate the height. It
is automatically calculated and taken into account in the
noise charts.
2.	Select the Proper Noise Chart
All the information has now been assembled for sel-
ection of the proper noise charts. The selection of the
noise chart Is determined by:
Aircraft type (in accordance with Table 1 )
Mode of operation (takeoff or landing)
Distance
The noise charts are listed in Appendix A. Each
noise chart covers a range of the distance D^, and several
charts may be needed to cover the entire range of D-^
values for each aircraft and mode of operation.
Noise charts are identified according to the code
listed below. This shows an example of the coding used by
the charts for the basic L, calculation:
dn
1| _ T - TFL(Q) - TO(I) - N - 1
(1) (2) (3) (4) (5) (6)
-32-

-------
(1)	The first number identifies the number of engines in
the aircraft.
(2)	This letter signifies either transport aircraft (T) or
general aviation aircraft (G).
(3)	The next group of letters identifies the type of
engine, as follows:
TJ -	Turbojet
TFL -	Low bypass ratio turbofan
TFH -	High bypass ratio turbofan
TP -	Turboprop
PP - Propeller driven by reciprocating
engine
LPP -	Propeller driven by reciprocating
engine (large)
SPP -	Propeller driven by reciprocating
engine (small)
TFS -	Turbofan (small)
The appendix (Q) signifies a quiet nacelle
engine.
(4) The mode of operation Is Identified with a T0_ for
takeoff and L for landing. (I), (II) or (III) refers
to the takeoff profiles associated with different
flight trip lengths when a detailed noise analysis
is being performed (see Section V-A). If the trip
length is not known, use profile (II).
-33-

-------
(5)	This group of letters refers to the special procedure
that may be used. The interpretation of the coding
is as follows:
S Standard takeoff or landing
N Northwest Orient Airlines noise abatement
takeoff
F FAR Fart 36 takeoff
T Two-segment approach
(6)	The last number of the code	identifies the number in
the set. The graphs within	a set encompass different
ranges of the distance Dn.	For the turbojet and
turbofan aircraft there are	usually three graphs in
a takeoff set and two graphs in a landing set. For
the propeller aircraft there are two graphs in a
takeoff set and one graph in a landing set.
For a given type of aircraft, look up the chart code
in Table 1 (page26) which will give the first three groups
of the code. If the operation is a takeoff and stage
lengths are not known, use the chart with TO (II) in the
code (if the stage lengths are known, see Chapter V).
Check also whether the airport uses standard or special
takeoff and landing procedures. Finally, look through the
subset of charts for the chart that shows the appropriate
range of D^. The desired SEL value is determined by first
establishing the Dg distance along the horizontal axis. A
perpendicular is then drawn on the graph to intersect the
proper value. The appropriate D1 distance is established
by interpolation between the bracketing curves. From
-34-

-------
this intersection, a line is drawn horizontally to inter-
sect the vertical. The point of intersection gives the
proper 3EL value.
C. Complete the partial Ldn value
1.	Calculate the correction for the number of operations.
The SEL value for a given type of aircraft and mode
of operation must now be adjusted for the number of times
this particular type of aircraft flies along this track.
This adjustment is made by subtracting the variable K which
is dependent on the number and distribution of day and
night flights. The equation* for K is 49.4 - 10 log (N^ +
10N„) and its solution is graphed in Figure 8. In Figure 8,
1\
find the nearest whole number value of K for the inter-
section of the number of daytine (Np) and nighttime (N^)
operations for the given type of aircraft, mode of operation
and track.
2.	Calculate the partial	value.
The partial	value [L^^(i,j)] is simply the arith-
metic difference of the SEL value found above and the ap-
propriate K value:
Ldn(ijj) = SEL^'^ " K(i,j)
The process is now completed for obtaining an
*See Equation 2, page 7
-3b-

-------

-------
value for class of aircraft and mode of aircraft operation
j. Repeat for each major aircraft type and node of op-
eration. Repetition will result in a set of Ld (i,j)
values. The total aircraft noise environment is then the
summation of these nartial L, values.
dn
D. Add the oartial L, values to obtain the total L,
	'	dn	dn
for aircraft operations
Since the partial	values are expressed in decibels,
they cannot be added together by ordinary arithmetic. In-
stead "decibel addition" is involved.* A chart for adding
sound levels quite accurately by "decibel addition" is
given in Figure 9. This chart can be used to an accuracy
of 0.1 d3, but most applications will not require (nor
justify) this degree of precision. A more practical ad-
dition procedure for quickly estimating the sum of two or
more decibel levels is given in the top of Table 2. The
use of this table will yield a sum that has an accuracy
within 1 dB. An accuracy within 1/2 dB can be obtained
*Remember that the decibel scale is logarithmic and ex-
presses the ratio of two quantities related to power
(with one quantity being a reference value). When L^
values to be combined are ("decibel addition")> the values
are combined on an energy basis. The rigorous procedure
for doing this is to convert the decibel numbers to
relative powers, to add the powers and then convert back
to the corresponding decibels. The availability of
scientific calculators that have 1G* and log^^x functions
makes decibel addition very easy and precise.

by using the lower half of Table 2. This degree of ac-
curacy in comparing	values will generally te adequate
for most calculations.
When a number of partial L. values are tc be added,
1	an	*
using Table 2 or Figure 9, they should be added two at a
time, starting with the lower valued levels and continuing
the addition procedure of two at a time until only one value
remains. To illustrate, suppose it is desired to add the
following five level??, using the summation procedure of
the upper portion of Table 2:
Addition of the partial L^n values completes the
procedure. Table 3 summarizes the basic calculation stops
that have been described.
E. Examples
The following two examples illustrate the procedure,
the first for a single aircraft operation and the second
for multiple aircraft, operations. Calculations for these
examples are given in Figure 10.

Consider a site exposed tc noise from takeofTs of
4-er.gine LBPR turbofan aircraft with the aircraft
departing along a curved flight path essentially
as shown in Figure 3 (page??). There are twelve
operations during daytime hours (between 7 am and
10 pm) and two nighttime operations (between 10 prn
and 7 am). The standard ATA takeoff procedure is
used but the stage lengths are unknown.
Measurement of the flight track on a map shows
that the distance D.; is 22 , 000 feet and the distanc
D- is 10CC feet.
ci
Entering the takeoff chart 4-T-TFL-TO(II)-S-3
which covers distances from 18,000 to 190,000
feet and using distance D~, value of 1000 feet, an
SEL value of 101.3 dB is obtained. Note that a
curve for equal to 22 , 000 feet is located two-
fifths of the distance between the D-^ curves for
20,000 and 25,000 feet.
The interpolation here can be done by inspection ox-
by calculation:

From Figure 8j the "K" value for equal to 12 and
equal to 2 is 3^5 dB. Therefore, as shown ir.
column 1 of Figure 10, the	is 66.8 dB.
Example 3 -
Consider the sane site as in Example 2. The airport
is considering a change in aircraft departure paths,
such that a large proportion of aircraft would make
a "straight-out" departure as sketched in Figure 11.
The total number of departures is unchanged. What
will be the change in noise exposure at the site
as a result of this change of operations? The
needed operational information is tabulated ir.
columns 2 and 3 of Figure 10. Eight daytime flights
have been changed from flight path A to flight path
B. The two night operations have been split between
the two paths.
The distance D- and D2 are tabulated in Figure 10.
The SEL values from 4-T-TFL—TO(I)-S-3 are also
tabulated. The new flight path results in an
SEL that is 2.3 dB lower than that for flight
path A.

Subtracting the "K" values obtained .from Figure 10

SECTION IV
METHOD FOR DETERMINING APPROXIMATE L, CONTOURS FOR
an
A SINGLE FLIGHT PATH
A. Calculate the Equivalent SEL Value
The procedures given in this manual enable you to cal-
culate the L^n value at a given ground position. They do
not provide an efficient way to determine contours (lines of
equal L^ values) which nay cover quite large land areas.
As noted earlier, standard computer programs are available
for generating Ldr contours.
For some planning purposes, it may be desirable to make
an estimate of contour size and dimensions for a specific
flight path. To accomplish this limited aim, this section
outlines a way of determing the approximate size and area
of a specified Ldn contour. The basic approach lies in
determining the dominant mode of operation (takeoff cr
landing), the most significant aircraft in terms of noise
contribution for that path, and then calculating an equivalent
SEL corresponding to the desired	values for which contours
are needed. Once the equivalent SEL value is determined, the
approximate contours can be determined, as outlined in Section
IV-B.
This procedure has several limitations. L^n contours
may be influenced by both takeoff and landing operations but
in this method, only the dominant mode of operation is con-
sidered. Another limitation is that in many locations, the
values are influenced by contributions from more than
one flight path; this procedure is based upon noise from
aircraft on only one flight path.
-47-

-------
The .method for calculating the equivalent SEL value is
described in the following seven steps:
1,	Identify the aircraft types and number of takeoffs and
landings per day for the three "noisiest" classes of air-
craft. Tn ranking the aircraft in terms of their contribu-
tions to the total noise environment, use the ranking of
aircraft given in Table 1*.
If takeoff operations comprise k0% or more of the total
operations, omit calculations for aircraft on approach. If
takeoff operations comprise less than 30% of the operations,
neglect the takeoff operations. Where takeoffs range be-
tween 30# and 39% carry out calculations for both takeoff
and landing a1.rc.raft.
2.	List the three classes of aircraft identified in Step 1
in the form given in Figure 5 together with the number of
day and night takeoffs or landings for each aircraft. Also,
list the appropriate takeoff or landing SEL values from
Table 1 for each aircraft. This value is identified as the
reference SEL value (S3L_) for that aircraft and mode of
operation.
*Table 1 lists the typical noise levels at a distance ap-
proximately 16, 00 0 fee i from start of takeoff or 6>000
from threshold, on landing threshold. The relative ranking
of contributions may well change for different positions
hence the listing in Table 1 is to be used for the purposes
of this analysis only.
-48-

-------
3. Determine from Figure 8 the adjustment factor "X" for
the number of day and night operations and list on Figure 5-
4. For each aircraft class, subtract the K values from the
partial day/night levels.
(iWr " S2Lr - k	••••
5. Add the partial	values as described in Section IIT-C
to obtain the reference L, value for takeoffs and/or for
an
landings. In cases where both landing and approach
values have been calculated (see Step 1), compare the landing
and takeoff values. If the landing value exceeds the take-
off	value by more than 3 dB neglect the takeoff value in
future calculations. If this is not the case, neglect the
landing values in further calculations.
This assessment results in selection of the dominant
mode of aircraft operation and establishes the reference L
value.
6.	Identify the dominant aircraft, which is the aircraft
that has the highest partial Ld value for the dominant mode
of operation.
7.	Obtain the equivalent SEL} SELg, for the reference L^n
value. The equivalent SEL for the dominant aircraft is
calculated as follows:
SELg - [Ldn - (Ldn)R] + SELr 	 (4.2)
-49-

-------
where L. is the level whose contour you wish
Gii
to calculate
(L, )„ is the reference value of L,
dn R	dn
SELd is the reference value for the dominant aircraft
n
The SELg contour size and shape is approximately the
»
same as the reference L, contour. The SEL„ is then used
dn	E
in Section IV-B to calculate the size and area of the L, _
anR
contour.
Example 4(a) You want to determine the approximate
size and area for the L^ = 60 contour for operations along
the track 27B at Mythical Airport (see Figure 6); ATA
takeoffs are used, but stage lengths are unknown. The
breakdown of operations on an average daily basis along
this track is now as follows:
Aircraft Type

Landings

Takeoffs

5 1
16 3

3 0
9 0
Looking at the ranking of Table I, it can be seen that the
Convair 440 ana Twin Otter can be eliminated from further
consideration, since only the three noisiest classes of
aircraft are to be considered. Looking, therefore, at the
74?, 707 and DC-9, it can be seen that there are a total of
53 takeoffs and 20 landings. Takeoffs comprise more then

-------
i\0% of all operations, so landings need not he considered.
Write the values of and N,., for each aircraft type on the
Data Collection Chart (Figure 12) and calculate the values

B. Determine the Approximate	Size of an SEL Contour
The procedure outlined in this subsection provides an
approximate method of determining the width, length and area
of an 3i£L con I our for a specific aircraft operation (take-
off or landing) er of determining an I,. . contour using an
equivalent, SEL value (SEL-,) . The procedure somewhat over-
estimates the size of the actual contour since it considers
only air-to-ground noise propagation ana neglects the in-
creased attenuation due to ground-to-ground propagation
which occurs when the aircraft is at a low elevation angle
with respect, to the listener. -

1.	Select the proper noise charts for the given aircraft
and mode of operation (if calculating an	contour, use
the dominant aircraft and mode of operation). The set of
curves can be identified as described in Section III-B.
2.	Determine the approximate contour closure distance.
The contour closure distance is the distance (from start of
takeoff roll or frorr the landing threshold) at which the
desired SEL value is attained along the flight track. This
distance is identified as A in Figure 13.
The closure distance can be determined from the noise
charts by finding the distance D, along the left vertical
axis for the desired SEL value:. (Note that since the
closure distance is measured along the flight track,
is zero). Interpolate between the curves to find the
desired value, and identify this distance as A.
3.	To find the maximum width of the SEL contour, de-
termine the maximum value of for any' value of D-^. To
do this, draw a horizontal line or. the chart (s) at the
specified equivalent SEL value. Find the intersection with
a Dt curve that occurs farthest to the right of the chart.
Read off on the horizontal axis corresponding to this
intersection, and denote this as 3. Where there is more
than one chart to a takeoff or landing set, as will usually
be the case, one should repeat this procedure for each chart,
and take the largest value of D£ as B*.
*As indicated in Figure 13> this procedure will result in
determining B the maximum, width of the contour. At
distances closer to the runway the noise contour may be
narrower than those calculated from the above method
because of the influence of ground-to-ground propagation.

b. Calculate the approximate area of the contour. The
approximate area of the contour is found from the following
expression:
Area - ^ x A x B = 1.57 x A x B .... (4.3)
This expression approximates the contour as a section
of an ellipse. This area is greater than the actual contour
size because the ground-to-ground transmission of sound is
neglected.
Example 5 -
You wish to find the approximate area impacted
by noise levels of 107 SEL and above as a
result of standard takeoffs of 4 engine LBPR
turbofan aircraft (707/DC-8). First, go to the
approximate set of noise charts
(4 - T - TFL - TO(II) - S - 1, 2, 3).
Figure 14, a copy of the second chart of this
subset, shows that when is zero (i.e. looking
along the vertical axis) an SEL of 107 occurs
for a value of = 15, 000 ft. Now moving -
horizontally along the line for SEL = 107, it
can be seen that the largest value of D^ is
about 1350 ft. (This occurs for = 8000,
but there is no need to record this.) Check all
the charts in the set to see that this is, in
fact, the largest value of

SECTION V
ADDITIONAL PROCEDURES FOR DETAILED NOISE ASSESSMENT
OR KON-STANDARD FLIGHT PROFILES
A. Use of Special Charts for Differing Takeoff Weights
The gradient of the takeoff flight path affects the
noise impact on the ground, and this gradient depends upon
the takeoff weights of the aircraft. The takeoff weight
depends on the amount of fuel carried, which in turn de-
pends on the stage length of the particular flight.
For detailed noise calculations, takeoffs for each class
of medium or long range aircraft should be further troken
down by stage length for that trip. The categories of
stage length depend on the actual type of aircraft and are
shown in Table 4. The data collection form should be
completed in the format as shown in Figure 15. The noise
chart should then be selected that has the same Roman
numeral in the fourth code group as the stage length
category cede.
3. Adjustment for Non-Standard Approach Glide Slope Angles
The approach noise charts for a jet aircraft given in
this handbook assumes a 3° glide slope, and although this
glide slope is found at many airports some exceptions may
occur. This sub-section provides a method for adjusting
the noise charts to predict SEL values for other glide
slopes.
Besides a change in flight geometry which results in
a change in the height of the aircraft at a given position

under the flight path, a change in glide slope also may
involve changes in air speed and engine thrust which also
produce changes in the SEL values. The method described
provides adjustments for the geometric changes but dees not
provide adjustments for a1r speed and engine thrust changes
that may accompany the change in glide slope. For minor
changes in glide an?Le, the air speed and thrust changes
are likely to be quite small. For large angle changes,
thrust and air speed changes may affect the noise .levels
appreciably.
Given a glide slope of x° and a position along a per-
pendicular to the flight path at a distance Dn (x), the
adjustment to the noise charts consists of finding the
equivalent C(D1)P" for a 3° glide slope that has the
same height (as illustrated in Figure 16). For glide
slopes greater than 3 degrees, the equivalent distance
will be larger distance than the actual D-^ (x); for glide
slopes less than 3°, the (D-, will be less.
Figure 17 provides a simple nomograph for finding the
equivalent distance to be used ir: the noise charts for
glide slopes ranging from 2.5 to 7°. This nomograph simply
solves the following equation.

through 9^. = . This line intersects the
right vertical scale (D^ at 3°) at 33,600 ft.
C. Guidance in Determining the Number of Positions for
L Calculations
For a small parcel of land calculation of the L, at
• dn
one position is sufficient. For a larger parcel, where
there may be a significant variation within the parcel
boundaries, calculation at more than one point may be
desirable. The practical question to be answered is,
"What is a small land parcel?" This question can be an-
swered by considering the accuracy of the calculations and
the magnitude of the variations in noise levels that is
felt to be significant. In the guidelines to follow, we
shall consider a small parcel as one where the expected
variation in L, or SEL values will be of the order of 1 dB
dn
or less. For such parcels, calculation at one position
should be sufficient. A larger parcel is one where it is
anticipated that the variation in noise levels will be
larger than 1 dB. Given this definition, general guide-
lines can be developed that will apply for the cases where
the aircraft is airborne — the guidelines will not gen-
erally be accurate for positions off to the side of the
runway where the land parcel is exposed to noise from air-
craft generated as the aircraft moves along the runway prior
to taking off.

1.	Determine D^ and Dp distances. Determine D-, and 1 ,
and and Dp' as shown in F1 gure 18. Note that is the
distance along the flight track tc a perpendicular drawn
from the flight track to the edge of the parcel nearest the
runway; ' is the distance to the edge of the parcel
farthest from the runway. Similarly, Dp is the distance
from along a perpendicular drawn from the flight track to
the edge of the parcel nearest the flight track and Dp'
is the distance to the edge of the parcel farthest from
the flight track. Thus D^ will always be large than D^1
and Dp will always be larger than Dp'.
With the D^ and Dp distances determined, the formal
guidelines described in the following steps may not be
necessary in determining the need for calculating
values at more than one position. One may simply estimate
the expected variation in r.cise over the land parcel by
inspection of the appropriate SEL charts, using the D^ and
Dp values determined in this step.* Where several aircraft
are involved, select the SEL charts for the aircraft likely
to be the dominant aircraft, i.e. the aircraft likely to
have the highest partial	value.
2.	Determine adjusted D-j^ values. To apply the guidelines,
the measured D^ values, as obtained above, must be adjusted
to represent the actual distance along the flight track
from the point at which the aircraft left the ground.
*This approach must be used to estimate the variation in
levels for a parcel exposed only to noise from aircraft
during the takeoff roll.
-67-

-------
(a)	For landings, the adjusted L\ values (D^*
and '*) are equal to the measured Dn
values plus 950 ft.
(b)	For takeoffs, adjusted values are equal to
measured values minus the distance from
start of takeoff roll to the point at which
the aircraft leaves the ground (liftoff point).
The' liftoff distance which is, cf course,
always less than the runway distance may be
estimated from Figure 13-3 through B-9 given
in Appendix B. (High precision is not
needed.)
3. Apply size tests. Calculate the quantity d where:
V* _ Dl*
d = 	npf	
If d is less than 0.12 the parcel may be considered to be
small with regard to variations in noise along the direction
of the flight track. If d is equal to 0.12 or greater,
the parcel should be considered large and calculations at
more than one position should be considered.
To estimate the variation in levels perpendicular to the
flight track, enter Figure 19, with the two quantities:

Locate the point or. the figure. If this point falls below
the appropriate curve (takeoff or approach) the parcel
should be considered as small and hence has an expected
variation of 1 dB or loss. If the point falls above the
appropriate curve, the expected variation may well be more
than 1 dB, and more than one calculation position should
be considered. If the value of D-*/Bp is less than 1 for
takeoffs, (f - D„)/D0 should be less than the 0.1 for
C-	c~	<—
the parcel to be considered small. Similarly, for the
approach, when D^/D^ is less than 2.H, (Dp' - Dp)/D2
should bo less than 0.1 for a small parcel.

This appendix contains the sound exposure level (SEL)
charts needed for calculation of day-night levels	)
for civil aircraft operations. The selection of the ap-
propriate noise chart is determined by:
Aircraft type
Xode of operation (takeoff or landing)
Distance
Aircraft types for which SEL information is provided
are identified in Table A-l of this appendix. The types
are listed in order of approximate noisiness. Table A-2
provides an index to the individual noise charts.
Each noise chart covers a range of the distance D, ,
J.J
and several charts may be needed lo cover the entire range
of values for each aircraft and mode of operation.
Noise charts are identified according to the code
listed below. This shows an example of the ceding used by
the charts for the basin J, calculation:

APPENDIX B
DEVELOPMENT OF THE AIRCRAFT SEL CHARTS
-353-

-------
APPENDIX D
DEVELOPMENT OF THE AIRCRAFT SEL CHARTS
This appendix briefly describes the analytical mcdel used
to develop the SEL curves presented In this handbook. The
appendix also summarises the noise and aircraft profile
information and data sources. More extensive information
and details may be found in the noted references.
A. Noise Model Assumptions
The SEL curves given in the handbook were developed from
two basic types of information:
(a)	Noise level curves showing the variation of SEL
values as a function of distance from the aircraft
at known air speed and thrust conditions.
(b)	Takeoff and landing profiles for each aircraft
showing the height of the aircraft above ground
as a function of distance from start of takeoff
roll (or landing threshold).
From a knowledge of the flight profiles, one can determine
the distances between the aircraft and the observer at any
point underneath or to one side of the aircraft (see Figure 2,
for example). Knowing the altitude and distance of the
observer from the ground track (which form two sides of a
right-angled triangle), one can calculate the distance from
the observer to the aircraft.
-355-

-------
For each aircraft, SEL curves were developed for both
air-to-ground and ground-to-ground propagation in accordance
with the simple analytic models given in Reference 1. These
curves assume air absorption for standard day conditions
(59°F ar.d 70 RH), as provided in 3AE ARP 866A. The ground-
to-grour.d curves also assumed excess ground absorption and
a b dB offset to account for partial shielding of the air-
craft noise sources at low angles of elevation.
The transition between air-to-ground and ground-to-ground
propagation is based upon the angle of elevation between the
aircraft at the closest point of approach and ground observer.
This angle, 6, is used to determine a transition coefficient,
T, where T is a function of 0 and varies between 0 and 1.
For 6 equal or less than 4.3°, T = 1 and the ground-to-
ground propagation curve is used. For angles of 0 or greater
than or equal 7.2°, T = 0 and the air-to-ground propagation
curve is used. For intermediate angles, (4.3° <0 <7.2°),
the following function is used: T = 2.5 -0.3491*0.
No correction is used for the possible fuselage shield-
ing effects of multi engine aircraft at ground positions to
the side of the aircraft flight track.
These assumptions are identical to those used in the
NOISEMAP computer program developed for the Air Force and
currently used for both civil and military aircraft
calculations.2 It should be noted that different assump-
tions as to the transition between air-to-ground ground-
to-ground propagation and shielding nay be employed in
other computer programs.3
-356-

-------
B.	Noise Data
For the larger civil transport aircraft, sets of noise
curves (SEL as a function of distance) were available for
different engine thrusts and air speeds. At specified points
along the flight path, changes were made to basic noise levels
to allow for differences in aircraft speed and thrust from the
reference conditions. For the smaller aircraft, generalized
takeoff and landing noise vs. distance curves were available.
Simplified takeoff profiles were used requiring fewer adjust-
ments of noise level data.
The major source of noise data was Reference . This in-
formation was supplemented by generalized curves for general
aviation aircraft provided in Reference 5. Figure B-l shows
a typical set of noise data for one cf the larger civil air-
craft and Figure B-2 shows a set of a composite data used for
the smaller general aviation propeller aircraft.
C.	Performance Data
For larger civil aircraft, basic takeoff profiles were
developed for different operating gross weights assuming that
the aircraft follow ATA procedures. The interpretation of
the ATA procedures used in developing these profiles is given
In Table B-l. The ATA takeoff procedures used for the transpor
aircraft are shown in Figures B-3 through 3-7-
For other aircraft, generalized takeoff profiles were
employed. These are shown in Figure 3-8 and B-9.
A 3° glide slope was assumed for the landing profiles
of all Jet aircraft and the heavier propeller aircraft.
For the smaller general aviation aircraft, a.glide slope of
4.5° was assumed.

Reference 1 provides most of the basic data for developing
the takeoff profiles and for determining thrusts for the take-
off and landing operations of the larger jet aircraft.
D. Special Takeoff Profiles
For the civil turbofan transport aircraft, SEL curves are
provided for two possible noise abatement procedures. One
special procedure is based on that development by Northwest
Orient Airlines.7 The other special procedure is based on
the allowable thrust cutback permitted by FAR 36.® The
interpretations of these procedures are given in Table E-l.
Figure B-10 shows a comparison of the three procedures
(ATA, NWO Airlines and FAR 3^) for a 4-engine LBPR transport
aircraft (707/DC-8). It should be noted that the handbook
graphs are based on thrust cutbacks at the heights specified
in Table B-l. Cutbacks at these heights may not represent
the "optimum" noise abatement procedure for alleviating noise
at individual airports.

16. abstract
A method is described for calculating the values of day/night level (Ldn).
at a point, due to aircraft operations from an airport. Two levels of
sophistication are detailed; (1) at the basic level, such factors as
type of takeoff and landing procedure are considered, but range and non-
standard glide slopes are excluded, (2) the more detailed method takes
account of the latter parameters. The procedure used is to locate the
position of the point in question, relative to the runway and aircraft
flight track. A series of charts give L<]n values for different types
of aircraft in terms of the distance parameters. Adjustments are made
to the single event noise level to account for frequency of operations
and the adjusted levels are added logarithmically to represent all of
the classes of aircraft using the airport.
