Flying Binghi:
Hasel Checks, for some sort of genuine compare i'm thinkin you would have to compare simular flight op's, e.g IFR heli and fixed wing op's from airport to airport, or perhaps heli and fixed wing mustering op's.... tho, even in mustering, fixed wing dont cover all the terrain types that helicopters do.
Good point, this brings home how difficult it is to compare the two.
I've witnessed close-up how Kiwi helicopter pilots use their machines for catching Red Deer, and the kinds of manoeuvres (and risks) they take are incomparable to fixed winged aircraft, (even crop spraying Fletchers!)
So whatever parameter was chosen to force a run-off, one could always dismiss it with the thought,
"Yes, but what is each machine accomplishing during its flight."
Interesting discussion though.
