I understand RAs mainly occur in controlled airspace due to pilot or controller error.
Are you suggesting this is an airspace design problem?
With so many of our airlines operating into places like Ballina and Port Macquarie where there is no transponder requirement for VFR I suppose there is less chance of RAs occurring.
But you don’t complain about this. I am proud I negotiated the most onerous class E transponder requirements in the world. I sold it on the fact that VFR may get reduced delays. I was conned on that one- the E was changed to C but the transponder requirement remained. Part of the almost complete lack of ethics in the Canberra system!
Total one way ratchet of increasing costs and screwing GA. Ha Ha. Chickens coming home to roost. Training industry almost destroyed. Must make you feel terrible!
