So if I've got this right LeadSled, I'll be able to cruise over Tullamarine willy nilly in class E at any time? That's what I'm hearing... have we ever been able to do that?
SWTT,
If that is the way the airspace was set up, above whatever the height of C was, the answer is yes.
I suppose you know that you can fly over Los Angeles International (and many other major US airports) in Class B airspace, in designated lanes, and nobody gets their knickers in a twist.
A lot of you could do with a dose of experience outside Australia, but particularly in US and Canada, to see how easy it is, things that you seem to imagine are beyond the pale (or, if you prefer, Pale).
And how well Class E works.
Tootle pip!!
