John - as Baldeep highlights, the training needs to be representative of the front-line task and it isn't. Also what might be acceptable for operational use is not guaranteed to be acceptable for training use.
Remember, you need a trainee and his instructor perched on the skid which doesn't leave much room for the winchman and makes a stretcher entry impossible.
I heard that an Ascent 'expert' was heard to say that stretcher entry wouldn't be a problem because the Air Ambos do it every day - then someone pointed out that they do it shut down on the ground and not in the hover...........Doh!
Oh dear, did the military go for the cheapest bidder??? That always works out fine...........
