I do not understand how Class E is the answer. You're talking about controlled airspace where IFR aircraft require a clearance (so will be separated), but VFR aircraft can waltz on through WITHOUT a clearance and WITHOUT RADAR surveillance. How is this safer?
717tec et al,
With the very greatest of respect, "you do not understand" only means you do not understand why Class E is such a widely used airspace category world wide, not just in the US.
The rest of the world that uses Class E is not dumb or stupid, they use Class E because it works.
What I don't understand is how any presumably normally intelligent pilot could possibly believe the Australia Class G arrangements are "safer", (lower risk) for the traveling public than for Class E.
Tootle pip!!
