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 of the Airport
The suburbs to the south of the airport are aligned with the south end of the main runway. Flights over this area are usually:
- Departures to the South – taking off into a southerly wind. This often happens in the afternoon.
- Arrivals from the South – landing into the northerly wind. This typically happens in the afternoons when the Fremantle Doctor blows.
In the calendar year of 2016, there were approximately 132,000 aircraft movements recorded at Perth Airport of which 41% operated over the southern suburbs.
