I wonder how many of those people who are opposed to the US model as a basis for an Oz system have ever flown there? Or anywhere else apart from Oz? How much of oppositional argument is based on local prejudice? There was a similar situation in the early '90s with the last great system change.
Similarly, how many of those for NAS have experience elsewhere, and under what system?
I realise that differences have been raised between NAS & US. How significant are those differences? Many people comment about lack of radar in Oz. Not all of the US has radar available although most places do. In terms of trafic mix & density ie comparing like with like, how much does the application of NAS in Oz differ from the US?
I have Oz, UK & US ATPLs. I vastly prefer the US system over anything I've seen so far - including Oz of up to 20 years ago. I'm not entirely sure, but I think I'd rather Oz contracted out it's need to the FAA & ditch DoA/DoT/DoTaC/CAA/CASA/Air Services.
