Oh Dick, you really have lost me this time.
How about we bust CTA airspace because we have not prepared/briefed our departure. At what point do we rely on our professional qualifications and run the operation as safe as possible without "running into a mountain top".
Oh you Wally!
Fact is Dick, there are a good many professionals operating who can accommodate the vagaries of Australian CTA/OCTA. It's not the best, but I'll do the best I can.
A Poor tradesman and all that(blames his tools).
