Every major airport has Noise Abatement Procedures (NAPs), which are designed to reduce the impact of aircraft noise on the community. They include procedures for runway use and flight paths to reduce flights over residential areas, as well as the designation of noise abatement areas. NAPs are implemented by air traffic control (ATC) but their use is not mandatory and is subject to weather conditions and aircraft requirements.
Airservices conducts regular reviews to check the effectiveness of NAPs and to seek improvements. At major airports, Airservices consults with community forums on the terms of reference for NAP reviews and reports are published on its website.
