As the United States has something like 20 times the traffic density in approximately the same land area, and as it is a very wealthy society (and also litigious), why can’t their airspace be used successfully and safely in Australia?
And becasue they have 20% more atc per airborne aircraft; and they are accutely aware of the litigous ramifications they do more than they are required by their own rule book. They do it with a more expensive system; fact.
You seem to be more interested in costs than systems; if you want to attack costs, 400 managers for 2600 staff would be a good place to start.
Dick, it's a real shame that you have decided to enter pprune again ignoring all that has been said over the last 5 days... Typical D.Smith attitude, ignore all contrary opinions and keep banging your own drum...
Question for you, Dick, why have any class E? Why not make it all class C with separation and free flight to VFRs? Is it the charges you resist or the 'permission' issues? Don't trump out costs, cause "C" is less ATCs than "E", fact.
Why have any E above A100. who uses it; where have the problems been?
Dick your comments last week were so appalling, you no longer give me any reason to take you seriously; Woomera, great try at making the thread worthwhile; but blah blah blah, who cares anymore; just make Dick go away and I'll feel a whole lot better.
