Introduction
1.1 Background
In accordance with recommendation 21 of the Proponent’s Statement for the Long Term
Operating Plan (LTOP) at Sydney Airport, Airservices Australia has prepared an Australian
Noise Exposure Index (ANEI) for the period 1 April 2012 to 30 June 2012 inclusive
(Reference Number N478).
1.2 Airport Layout
Sydney Airport has three runways. Runway 07/25 (2529m long and 45m wide), Runway
16R/34L (3962m long and 45m wide) and Runway 16L/34R (2438m long and 45m wide).
The runway end coordinates and elevations, Aerodrome Reference Point coordinates,
elevation data and displaced threshold information for Sydney Airport were obtained from
airport data held by Airservices Australia and are shown in Table 1.1.

The Integrated Noise Model (INM)
The Integrated Noise Model version 7.0c (INM 7.0c) developed by the US Federal Aviation
Administration (FAA) as a means of evaluating the impact of aircraft noise was used to
model the noise contours for the period 1 April 2012 to 30 June 2012 for Sydney Airport.
2.1 INM Terrain Data
The INM program can import and use terrain elevation data for use in calculating noise
metrics. The terrain data is set out in a grid format and includes elevation above mean sea
level. The INM interpolates this data to prepare the ground contours for presentation at the
required interval. Terrain data has been used within this ANEI study. Areas to the north,
east and west of Sydney airport are higher than that of the airport, which has had the effect
of increasing the extent of the length and width of the ANEI contours in these areas.
2.2 Changes Incorporated in INM Version 7.0c
At the time of preparing this report, INM7.0c was the most recent release of INM including
database updates and correction of minor software issues.
INM Version 7.0c includes approach noise data updates for many existing Airbus aircraft
types, which are considered to better represent the approach noise generated near an
airport and address a reference speed assumption issue in the INM Version 7.0b approach
noise data for these aircraft.
Minor corrections were also made to the data for several existing aircraft for INM Version
7.0c, details of which can be found within the INM 7.0c Release Notes.
As of 2010, a change has also been made to the way helicopters have been incorporated
into the current study. Helicopters have been modelled with their own profiles and helipad,
details of which are given in Section 3.3.
Because of enhancements made to INM7.0c, care should be exercised when comparing this
ANEI with studies that were prepared using earlier versions of the INM program.

Methodology Used in the Development of the ANEI
3.1 Introduction
The ANEI contour is based on the data collected by Airservices Australia’s Noise and Flight
Path Monitoring System (NFPMS). The NFPMS went through a major enhancement during
the latter part of 2009. These enhancements have enabled an improved process for
generating the ANEI contour for Sydney Airport. The main improvement has been made in
the way aircraft movements have been allocated to modelled tracks. This change is detailed
below in Section 3.2.
The development of the ANEI consisted of the following stages:
i)
collection and verification of the required data;
ii)
preparation of the data as INM input files;
iii)
running of the model; and,
iv)
preparation and verification of model’s output.
3.2 Collection and verification of the required data
Runway and associated airport data were obtained from airport data held by Airservices
Australia’s NFPMS. The total number of movement records from the NFPMS data for the
study period is shown in Table 3.1.
As part of the routine data verification of the NFPMS records, flyover movements are
checked to determine whether any of these aircraft had made an arrival or departure at
Sydney Airport. The records that could not be described as a movement at Sydney Airport
are excluded from the study.

including Helicopters)
# General (Touch and Go

Helicopters)
Total
78,072
# Note that the touch and go movements above have been doubled in the total movement
count.
There were 35 unknown aircraft types within the study period. The NFPMS movement
numbers were adjusted to account for unknown aircraft types for input into the INM study.
This was achieved by increasing either the arrival or departure number to ensure arrivals
equals departures by aircraft type. This process did not exclude aircraft types or movements
from the data set. Touch and Go operations were split into arrivals and departures evenly.
Movement data derived from Airservices Australia’s published ‘Movements at Australian
Airports’ for Sydney Airport for the period of 1 April 2012 to 30 June 2012 and the daily
average aircraft movements for this period are shown in Table 3.2. Note that these numbers
vary slightly to the total movements captured by the NFPMS. In previous ANEI models, the
NFPMS movements were then factored to the Avcharges recorded number of aircraft
movements and the daily average number of movements was calculated. This factoring
Environmental Services

Report N478

calculation has not been performed since Q1 2010 due to improvements in the data integrity
in the NFPMS.

The flight tracks used in the model were determined from the NFPMS. Flight track plots
from the NFPMS were used to identify the major flight paths associated with aircraft
movements to and from the airport.
A nominal backbone track for all the major flight paths was identified by means of
geographic coordinates along the length of the track and from NFPMS track plots. The
corresponding spread for each track was also determined from the NFPMS plots. These
tracks were entered into the INM as ‘point type’ tracks. Each ‘nominal backbone track’ was
prepared with subsidiary tracks that provided a realistic lateral spread of traffic along the
nominal tracks.
3.3 Preparation of INM input file
The aircraft movement data extracted from the NFPMS were organised into:

track flown;

aircraft types and the associated operation (departure or arrival);

the runway used; and,

the time of day or night.
For the purposes of modeling and using the Australian Noise Exposure Forecast (ANEF)
metric, night is considered to be between the hours of 7:00pm and 7:00am and carries a
weighting of 4.
Including terrain information around the airport improves the accuracy of the contour and
was taken into account. Terrain data for the Sydney region was compiled in accordance
with the INM User’s Guide into a format suitable to be read by INM 7.0c. The terrain data
was aligned to the Aerodrome Reference Point (ARP) and incorporated by INM when
calculating the ANEI contours.
The use of terrain data changes the shape of the ANEI contours when compared to a flat
ground model. Variances in ground elevation change the distance between the aircraft and
the ground, hence the calculated aircraft noise levels at each grid point on the ground.
The types of aircraft that operated at Sydney Airport were assigned to 37 representative
aircraft types that are contained within the INM database and are shown in Table 3.3.
Where possible, the actual aircraft type was matched to its INM counterpart. However, in
cases where a particular aircraft type had a small number of movements, it was grouped
with a major INM type or INM substitute.
In this study, helicopters were modeled using actual helicopter profiles within INM.
Representative helicopter types were used to assign helicopter movements (EC130, R22
and R44). These helicopters were chosen because they contain the appropriate Noise
Power Distance (NPD) curves data relevant for the ANEI noise metric and they represent
helicopter movements at Sydney Airport. All helicopters that operate at Sydney airport were

then assigned to the representative type based on size. Helicopter types that were unknown
were assigned to the R22 helicopter. All helicopters were modeled as arriving to or departing
from the Helipad that is located south of the threshold of Runway 25.
The aircraft types were assigned to representative back bone tracks based on their track
location within the NFPMS. As stated previously, the INM tracks were prepared as point
type tracks, the location of which, and lateral spread, being determined from the NFPMS
data for each ANEI prepared for Sydney airport.

3.4 Running of the Model
The INM was run using standard noise profile data for each of the aircraft types. The
parameters used for the ANEF metric were:
Day multiplier
1.0
Night multiplier
4.0
A derivation for the ANEF metric can be found in Attachment A of Australian Standard
2021:2000 Acoustics, Aircraft Noise Intrusion – Building Siting and Construction. In
accordance with the standard, the evening multiplier is included as part of the night period
(7:00pm to 7:00am) and is not modeled.
3.5 Preparation and verification of the model output
The ANEI contours produced by the INM were plotted using a GIS software package onto a
base map. The contours produced for the 1 April 2012 to 30 June 2012 ANEI (N478) are
consistent with flight tracks and the aircraft operations for the period and the use of terrain
data.
Table 3.4 shows the average daily aircraft movements for the 1 April 2012 to 30 June 2012
ANEI (N478) is 19 movements higher than for the same period for the previous year - the 1
April 2011 to 30 June 2011 ANEI (N473).

Comparison of the 2012 ANEI (N478) with the 2011 ANEI (N473)
The 1 April 2012 to 30 June 2012 ANEI (N478) contours for Sydney Airport are shown in
Attachment D. For comparison purposes, the 1 April 2011 to 30 June 2011 ANEI (N473) for
Sydney Airport has been included as Attachment E.
The N478 contour was produced using INM7.0c, whereas the N473 contour was generated
using INM7.0b.
4.1 Comparison of ANEI N478 with ANEI N473
The changes evident in the contours for ANEI N478, when compared with the contours for
ANEI N473, are consistent with the changes in aircraft types, movement numbers, runway
usage, night movements and aircraft flight path use during the two periods.
Table 4.1 shows a comparison of average daily arrival and departure movements by runway
for ANEI N478 and ANEI N473. Note that this comparison provides the basis for evaluation
of the ANEI N478 contours. When INM disperses the movements assigned for each aircraft
type from the nominated ‘nominal backbone track’ to its subsidiary tracks, there are
sometimes slight differences between the reported number of arrivals and departures for that
aircraft type, runway or INM study due to rounding.

Number of Aircraft Noise Events Above 70dB(A) Noise Map
5.1 Introduction
‘Number Above’ (Nxx) noise maps are an approach which provides additional information on
aircraft noise in a form that is more easily understood by the community. The contours
provide a visual depiction that shows the number of noise events during a given period that
are louder than a selected threshold level. The N70 Aircraft Noise Map for Sydney Airport
shows for all areas around the airport how many aircraft noise events louder than 70 dB(A)
there were, on a daily average, during the period from 1 April 2012 to 30 June 2012 ANEI
(N478).
70 dB(A) is generally considered to be the external sound level below which no difficulty with
reliable communication from radio, television or conversational speech in a typical room with
windows open is expected. (Reference - Department of Transport and Regional Services,
2000, Expanding Ways to Describe and Assess Aircraft Noise, pp23-35).
5.2 Methodology used in the Development of the N70 Aircraft Noise Map
The N70 aircraft noise map was prepared using the same input files as those for the ANEI
contours and was prepared by running the Time-Above (TA) metric, which is a standard
metric within the INM 7.0c, to produce a detailed grid output file. It is important to note that
the TA metric, unlike the ANEF metric, does not use any night weighting in the calculations.
The detailed grid output file was then modified using propriety software and then imported
into a GIS software package for plotting onto a base map.
5.3 Analysis of the N70 Aircraft Noise Map
The N70 map prepared for Sydney Airport is shown in Attachment F – Sydney Airport N478
N70 Aircraft Noise Map - 1 April to 30 June 2012.
The map output is consistent with the patterns that would be expected given the position of
the flight paths and the number and types of aircraft using the flight paths modeled in the 1
April 2012 to 30 June 2012 ANEI (N478).
The N70 aircraft noise map provides information on the total number of aircraft noise events
that exceeded 70 dB(A) in a grid area that were likely to have interfered with conversation,
sleeping and listening to the radio or television inside a house with the windows open.
However, it is important to note several limitations with the N70 aircraft noise maps. These
include:
 Unlike the ANEI computations, ‘Number Above’ metrics are based on a large INM grid
format and have so far had limited use in formal noise assessment documents in
Australia and they are therefore not tested or verified. The figures that may be derived
from the N70 aircraft noise maps are therefore purely indicative.
 The INM does not provide users with a direct way of computing a ‘Number Above’
chart, unlike the ANEI and TA contours. It is only possible to derive ‘Number Above’
values on a rectangular grid, which is then processed for importing into the GIS
software package. The accuracy of the N70 contours shown in Attachment F is
therefore at best plus or minus 500 metres, the distance between grid points used by
INM in the calculations. In addition, the superimposed contours may have incurred
errors in the transformation from INM coordinates to the map coordinates that were
used in the preparation of the N70 chart.

Notes
1. Contour and Suburb population totals are calculated using the non-rounded values. The totals are
then rounded to the nearest 100.
2. A Contour may overlap a Suburb but have no population under the contour. This can occur
because the population distribution within a Suburb is modelled to ensure that there is no significant
population in parks, reserves and industrial areas.
Data and Methodology
Suburb and contour population counts are approximations based on Census District (CD) populations
from Census and Suburb Boundary information from MapInfo Australia. Populations are calculated
according to the proportion of the area of overlap of a suburb/contour on a CD to the CD total area.
Some editing of CD boundaries and populations was performed to accurately reflect population
distribution in critical areas (close to the airport or flight paths).
