Noise Abatement Procedures at Perth allow aircraft to be taken off Standard Instrument Departure (SID) procedure tracking once jets are at 5000 feet above ground level and non-jets 3000 feet except where impractical in the normal course of operation to and from the runways. This provision is primarily in place to assist the efficient management of aircraft close to the airport during peak periods.

In response to community concerns about the minimum height of aircraft over residential areas, Airservices held a trial from December 2013 to February 2014 for all aircraft flying to the east of Perth to maintain SID tracking until leaving 8000 feet except where required for operational reasons.

A Post Implementation Review of the trial was completed in December 2014. While community feedback was limited, Airservices concluded there was a noticeable benefit from the trial and that the change should be permanently implemented in Perth Airport’s Noise Abatement Procedures. This change was permanently implemented on 28 May 2015.
