Clint, with respect, you still don't get it.
It is not up to CASA to speculate, or pontificate. The rules and compliance requirements and objective standards should operate from North to South and East to West. There must be no discretion. If I comply in Tasmania, I comply in the Pilbara.
We can then have discussions about mixture pull, etc. on a nationwide basis (type by type if necessary) and an end to uncertainty.
This is what is killing GA. "Maybe you comply, and maybe you don't".
It will kill RA too in due course. It has already deterred me from $60,000 worth of investment until (if ever) I can obtain certainty about construction and operational requirements.
