Airservices identified an opportunity to modify the flight path for aircraft arriving from the north to land on the southern end of the Runway 03 at Perth Airport which would move aircraft away from Bickley, Byford, Carmel, Martin and Roleystone and closer to Bickley East, Karragullen and Pickering Brook which had smaller populations.

A Post Implementation Review of the trial was published in February 2015. The review found that community feedback demonstrated a noticeable benefit had been achieved from the trial and that as a result the change should become permanently implemented. Airservices actioned this on 5 March 2015.
