OK lets try it this way then.
And I'll support mandatory transpoders in all aircraft sharing airspace with 10-30 seat RPT's and charter if you support mandatory TCAS for them.
I agree the airspace belongs to the Australian public in the same way as the national road sytem.
But nobody complains about Australian Compliance Standards for the vehicles that use them which although undoubtedly means extra costs undoubtedly saves lives. Or dont we need these excessive costs out there in the GAFA.
