You state
One interesting observation, is that CASA intend for Class D procedures at the ex-GAAP's to be different to procedures at existing Class D aerodromes
That's because the procedures at our existing Class D aerodromes will also change to US Class D.
Coral, let’s hope you are 100% correct. That’s the whole idea of the CASA Direction. All of our non-radar towers will have the same procedures – all simplified, all following common sense, and all following the proven US NAS system.
When this goes ahead it will be a great improvement for everyone. I know of even reasonably high time GA pilots who will not fly into a place like Tamworth or Coffs Harbour because of the complexity of clearance requests, clearance limits and departure calls, etc.
