An AOC (Air Operator's Certificate) is a CASA approval for an organisation to carry out a commercial aviation enterprise. With it comes CASA control.
Many GFA organisations have AOC's as have RA-Aus organisations.
Nobody said RA-Aus itself had One.
Oh! and balloons don't have "certified" engines similar to a number of SAAA and Warbird aircraft that can and do fly in CTR.
I suppose you all know Bankstown, Archerfield, Jandakot etc are "control zones"
How far do you want to take this? Is a certified VW OK? And don't tell me they don't exist.
I'm bored already.
