Perth Airport - Change to Runway 24 Approach Procedure

Consultation has concluded.

Airservices Australia is changing the procedure for the area navigation approach, known as RNAV-Z, to Runway 24 at Perth Airport. Runway 24 is the north-east end of the cross runway, near Hazelmere. This change is scheduled to start on 23 March 2023.

Approximately two per cent of around 100 arrival flights on a current typical busy day on Runway 24 use the RNAV-Z approach – around two arrival flights per day.

The RNAV-Z approach uses on-board global navigation satellite system technology to provide guidance to pilots and starts close to the suburbs of Hovea and Parkerville, about eight nautical miles (or 14.8km) from the Runway 24 landing threshold.

Airservices is changing the RNAV-Z procedure by lowering the minimum start altitude from the current 2,800ft (850m) to 2,500ft (760m). This change allows the descent angle of aircraft flying the approach to be reduced to the International Civil Aviation Organization’s recommended optimum three-degree rate of descent. It also means aircraft using the RNAV-Z approach will have the same minimum start altitude as aircraft using the alternate approach procedure to Runway 24.

This change to the RNAV-Z approach may lower the altitude of aircraft overflying the area shown in the image below, which includes the suburbs of Gidgegannup and Parkerville. The expected change in aircraft noise levels over these areas from aircraft using the changed RNAV-Z approach is an increase of approximately two decibels (dBA). Changes in noise levels of up to three dBA are unlikely to be perceptible to the human ear.

This change will not affect the total number of flights operating at Perth Airport. There are no changes to existing flight paths and no new areas will be overflown.
