Aircraft Noise Information Tool

WELCOME TO THE AIRCRAFT NOISE INFORMATION TOOL FOR THE SUNSHINE COAST AIRPORT.

With this tool you can review indicative aircraft noise modelling for existing and future operations, including flight paths and typical jet overflights per day.

HOW TO USE THIS AIRCRAFT NOISE TOOL

Please note:
- Ordinary Google Maps navigation is enabled in the map.
- Some functions are not supported by all web browsers / mobile devices. For best performance, we recommend using an updated version of Chrome, Firefox or Safari on a computer or tablet.
- For more information about each menu item, click the corresponding information icon.

NOISE MEASUREMENT MENUS
1. Click the ANEF/ANEC, N70 or B787 LAmax buttons to select the type of noise measurement you want to view. The selected type will be highlighted green.

NOISE CONTOURS FOR DIFFERENT SCENARIOS
2. Click on the scenario you want to view (Existing, 2020 or 2040). The scenario will be highlighted green and a contour will be shown on the map.
3. To 'lock' a scenario on, click and hold the scenario name, until the scenario is highlighted yellow.

ADDRESS SEARCH
4. Search for an address by typing in the address box at the top of the map.
5. Either select the address in the drop-down list or press enter when you have finished typing.
6. To clear the address and search another, retype into the address box.

FLIGHT PATHS
7. Click on the "Show/hide flight paths" button to display indicative flight paths.
(Note that this functionality may cause the noise tool to run slowly on some devices)

PRINTING
8. To print the current map select print from your browser's menu ("Right-click" outside the map area and select "print" in most browsers). For best results on some browsers you may need to enable printing background colours (Google "print background" and your internet browser - e.g. "print background firefox").

RESET
9. To reset the map hit the 'reset map' button.

ANEF

The Australian Noise Exposure Forecast – or ANEF – is the accepted measure of aircraft noise exposure for land use planning in Australia. The measure takes into account many factors including noise level, frequency and time of day for aircraft noise events. ANEFs are primarily used by state, territory and local government planning agencies for land use zoning purposes.

Further information, including a table detailing acceptability of development within each zone, can be found on our website under ‘Flight Paths and Aircraft Noise’.

N70

How often you’re likely to hear aircraft noise louder than 70 decibels is shown on the ‘How often?’ contour map. The areas within N70 contours represent the number of single events – that is, the take-off or landing of an aircraft – per day that measure 70 decibels or above, which is the noise level deemed likely to disturb conversation. For example, a person at an address falling within the ‘5-10’ contour could expect five to 10 single aircraft noise events per day exceeding 70 decibels.

LAmax

‘LAmax’ is an acoustic measure commonly used around the world to describe how loud jet overflights may be in various locations. LAmax contours represent the maximum noise level likely to be experienced within a given area during a single overflight of a specific aircraft type. SCA’s LAmax contour modelling is based on one of the loudest aircraft types – the B787 – expected to be in use by 2040, so provides a ‘worst case scenario’.

Existing

The "Existing" scenario represents the noise modelling results based on historical data. Existing operations would continue until commencement of sand pumping works, which would require the closure of existing runway 12/30.

Do Minimum

The "Do Minimum" scenario assumes the existing runways and operating procedures, and a forecast of future aircraft movements at the airport. This case assumes that necessary actions will be taken to permit the continued use of runway 18/36 for classes of aircraft that currently operate on this runway.

Proposed New Runway

The "Proposed New Runway" scenario forecasts the noise impacts with the proposed 13/31 runway in operation.

Runway 18/36 (Existing)

The "Existing Runway" shows flight paths for the 18/36 runway in operation.

Runway 13

This shows the proposed flight paths for Runway 13 in operation. Departures are to the northwest and arrivals are from the southeast.

Runway 31

This shows the proposed flight paths for Runway 31 in operation. Departures are to the southeast and arrivals are from the northwest.

Runway 13/31

Each end of Runway 13/31 reflects the runway's orientation, with Runway 13 at the north-west end, and Runway 31 at the south-east end. This indicates which end of the runway pilots should use to start their take-off or landing based on wind conditions. In easterly winds, which are typical for the Airport’s location, aircraft will use Runway 13, arriving over land from the north-west and departing over the ocean to the south-east. When winds are westerly, aircraft will use Runway 31, arriving over the ocean and taking off over land to the north-west.
