Let's face it, the whole thing is a big mess, because GA was not considered when the rules were drafted. The rules that currently exist do not make any provision for GA operators or pilots that do not hold an ASIC. The problem is that the rules and instructions to aerodrome operators should make a provision for pilots to come and go etc. Fix that and the problem for GA pilots landing at such aerodromes will go away. Or an alternative would be to formalise the AVID in some way and have it recognised as a ID for GA areas of such aerodromes. To solve this problem we firstly have to have it demonstrated that it is a problem and then come up with some workable solution/s. Something that AOPA, RAAus and the other groups should get together on.
