Then you would have used a DHC6 Twin Otter because it could lift more out of the same space!
Far cheaper too!
When Shell Oil (Nigeria) went from Bell 212's to the EC-155....the Heliports became runways....that should tell you something about the effects of using Cat A profiles and performance.
I have practiced the "Reverse" Takeoff Profile....never ever did one for real in daily operations.
Also did some very convoluted gyrations in other aircraft that were supposed to provide for Cat A performance (with a very limited weight allowed) as well....but in the end would have been far happier just flying the machine like a helicopter it was.
I was never on a Civliian operation where an engine failure on Takeoff ever occurred....not that they do not.....just they never did anywhere I was based.
