Banjup residents will have been disturbed by light aircraft flying south over the past few weeks. Sometimes noisy planes fly over south Banjup every minute or so at 1,000 feet.
Your Committee has contacted Jandakot Airport Operations and Air Services Australia(who run the control tower) to discover why there has been a dramatic increase in over-flights when there have been almost none before. Having rejected the drivel we received from Air Services Australia, we eventually received a plausible answer from Jandakot Operations:
“Our parallel [i.e. the main] runways 24/06are used 70% to 80% of the year and aircraft departing to the south track over Thomsons Lake. However, in summer and particularly over the last two months or so the easterly wind has been blowing almost everyday and our runway 12 has been in use. When this runway is in use, departing aircraft to the south do in fact depart over Banjup. They have departed in this manner for many years but perhaps because the easterly wind has blown so consistently of late it has been more noticeable. With the arrival of autumn, the easterlies should soon cease and I believe that the air traffic over Banjup will decrease accordingly.”
A check of the Bureau of Meteorology’s Jandakot weather observations here confirms that easterlies have been blowing most days in February and March.
It is unclear why pilots taking off from runway 12 cannot turn westwards north of Armadale Road and still track over Thomsons Lake as they do when westerlies are blowing. Your Committee will take this up with Air Services Australia through the ‘Community Aviation Consultative Group’ here that we hope to join soon.
Banjup residents can see real time and historical flights passing over Banjup from Jandakot Airport on the Web Trak facility at http://webtrak.bksv.com/per .

Members who attended the May General Meeting will recall that the meeting was informed that the increased commercial aircraft noise over Banjup was due to runway works at Perth airport that would be completed within a few weeks and that diverted aircraft would then return to their usual flights paths (ie not over Banjup). I must report that this is NOT the case.
The runway works at Perth airport completed on 4 June were never the cause of aircraft flying over Banjup. Air Services Australia in November 2008 permanently changed flight paths around Perth and one approach for arriving aircraft takes them directly over Banjup, typically tracking along the eastern end of Gibbs Road and then turning north to track along Boronia Road and thence directly to Perth airport.
Apparently, Air Services Australia conducted the Western Australia Route Review Project (WARRP) which was a comprehensive review of airspace use, flight routes, and aviation procedures across Western Australia. The review was undertaken between 2006 and 2008 and included public consultation. Changes were implemented in November 2008. You can find the report here.
The WARRP report tells how flight paths over Perth were changed because of increased traffic at Perth airport and to make flights safer, given the increased use of Jandakot airport and Pearce airbase. Diagrams of the changes are here. You will see that paths were added to bring arriving planes over Banjup. You can see months of real time aircraft movements using an application named Webtrak, which is here. If you set the calendar in the bottom left corner to, say, 30 May 11 at 0830, then you will see simulations of the flights into Perth airport at that time. Set the replay speed slider to 10 and zoom in on the map so that Banjup is in the middle and you can read the street names. You will see that many planes turn directly up Boronia Road. If you want to see what planes are going over you right now, then check the current flights box in the left corner panel.
The extent of public consultation afforded to Banjup residents in 2006 is not clear but it would have been best to have made our views known then. However, it is also not clear why aircraft turn right over Boronia Road when they could equally well turn right between Taylor and Nicholson Roads which is over pasture land and would disturb significantly fewer people. If you wish the Banjup Residents Group Committee to take this up with Air Services Australia, then please add your comments below on this page.
