Blenderpilot, were there any wind limits set on these failures, especially minimum ones? In a 206 you can make a survivable auto from many configurations that would kill you in an R22 or similar low rotor inertia helicopter.
I know you are referring to my comments on the 'cap thrown at helicopter' thread but many people fly low inertia rotor systems and if they think they can get away with EOLS from deep inside the HV curve they are wrong.
Bear in mind 2 things - 1. you were practising these hover EOLs ina controlled environment, you knew the failure was coming and therefore there would be no delay between throttle chop and lowering the lever (not a realistic representation of the real world or the HV curve data) and 2. you were doing them to water with big cushioning floats on, not with skids to a hard surface (again not representative of the real world).
You mentioned in your post on the other thread that when you did this the lever had to go down and up again lightning fast and the resulting landings put "crayfish on the windshield" so if the student made any error at all how was the instructor going to rectify the situation?
I am sure it was great training but at what potential cost? how many pilots have had to auto to the water following an engine failure in a single from a high hover? very few I guess.
