Matt-YSBK, you are onto the correct point. Of course at Bankstown you can’t come in from 360 directions, about 180 of them are prevented because of the Sydney control zone and those huge unnecessary military restricted areas to the south.
I worked for years to try to remove the restricted areas so aircraft could come in from the south, improving safety. I failed at this, even after meetings with the military.
This should allow us to at least bring in aircraft approaching from the north. The more random you can make the entry points, the higher level of safety you obtain. That’s what they tell me from overseas experience anyway.
