Where is the standardisation that gives guidance to rurual airfield operators as how they facilitate GA ops by pilots that do not hold an ASIC?
Pretty simple really, if you want to have access at a security controlled airport that has screened services - ASIC 24/7. Airports without screened services you can apply Regulation 3.03. The sticking point there though is that many airports specify ASICs at all times regardless. Would be a very interesting test case.
So after reading the comments here I am wondering what was the purpose of Dick's question? I suppose he could point the finger at the GG of the time who signed off on the Aviation Transport Security Act 2004. What does it matter who played what part?
