Running in below ‘aerobatic’ minima. It’s my understanding that this is legal, as the definition of an aerobatic manoeuvre is not reached until one is above the 500’. There are plenty of examples of that.
Those who ignore the possibility of TIA and condemn AH for recklessness and demanding his head on a plate are misguided.
