Well that’s disturbing.
I guess taking into account the small area of airspace, and the large amount of traffic (airline) that takes place over there, the ultimate goal for them would be to eliminate the entirety of GA. Weekend warriors are not welcome. Would the CAA stump up roadshows around their land educating GA pilots on how to be safer?
While GA is fading away here, and there are many other factors at play making that happen, not solely CASA. Your local greedy council and developers have a lot to answer for.
