many types are limited by their certification to a max of 60 deg bank angle per the Flight Manual.
Surely the missing ingredient in this thread is in fact the flight manual. If a normal or utility aircraft allows stalls, then isn't that inferring that its not an aerobatic manoevre? At least in the mind of the designer.
I think one of the problems with these debates is, in fact, the use of the term "stall".
If stalls are not prohibited, are manoevres below the 1g stall speed allowed with AoA below the critical angle (ie pushover)?
Is level flight above the 1g stall speed allowed with AoA above 15 degrees (ie high speed stall)?
Should the definition be based on AoA?
Or we could just teach pilots to fly properly in all conditions and be done with it!
I seem to recall someone doing negative g turns in the circuit??????
