"Oh No!" chimed in an ATC person. "If we get ADS - B signals that aren't of the required accuracy, then we are going to have to put 25 mile buffers around the source aircraft to ensure separation".
Here is part of the lie.
Australia is THE ONLY COUNTRY IN THE WORLD mandating ADS-B for ALL IFR aircraft at ALL levels in ALL airspace types.
BUT, ADS-B is only mandated for IFR aircraft, but not VFR.
So, where are the benefits to GA? The ATC person is effectively saying that I will get no benefit from the reduced separation requirements of ADS-B.
I have had 3 near misses that have frightened me. In each case I was IFR on an IFR plan and the other aircraft was a NO DETAILS VFR flight. One of these was at 10,000ft and one was while I was in cloud. ADS-B will not improve safety in any of these instances.
