How Perth Airport Operates
Take-off and landing – For safety, aircraft must take-off and approach into the wind as much as possible. This assists the aircraft with producing lift, provides more control and reduces the amount of runway required. Therefore the wind direction generally dictates which runways are used at Perth Airport.
Approaching the runway – For safety, it is important that the manner in which pilots approach a runway is similar around the world. Arriving aircraft will generally approach a runway in a relatively straight line from around three to four kilometres from the runway end and at a three-degree angle. This three-degree ‘glide path’ follows a line that descends about 100m every two kilometres.
Flights over Suburbs to the South West of the Airport
The suburbs to the south west of the airport are aligned with the west end of the cross runway. Flights over this area usually occur when runway works/maintenance is being undertaken or if a strong cross wind prevents the safe use of the main runway:
- Departures to the West – taking off into a strong westerly wind.
- Arrivals from the West – landing into a strong easterly wind.
In the calendar year of 2016, there were approximately 132,000 aircraft movements recorded at Perth Airport of which approximately 6% operated over the south western suburbs.
