Why Helo Dunker training is good....

I read somewhere that the helicopter in that vid lost one of it's engines, and tried to take off again with one.
Sure looks like they tried to lift off again, but just couldn't quite make it. It looks like it had some kind of floatation deployed though... might have been better to just shut 'er down and egress right then and there.
@ Fezz dunker: Just don't release your seatbelt too soon or you'll wish you hadn't.

It depends on the kind of helo. An H-3, with its boat hull, won't sink assuming it remains upright. An H-60 (without flotation) not so much. Helos do like to flip over, just like the helo dunker, because of the top heavy nature of a helicopter. I have heard that 60's will float upside down for a short while if there is air in the fuel tanks, but I don't know how true that is.

Well generally one shouldn't have to stick around to find out. :icon_wink
I'm no helo expert (obviously), but is it possible that this was just a training maneuver gone bad? Such as the waves provided to be too choppy for him to judge the angle of attack upon lifting off...please someone with more knowledge step in so I don't make myself look more stupid.

AOA? WTF are you talking about?

You studs and nuggets in the HT's/FRS take note - Looks like the aircraft (Mi-14 by the way) went single engine and was unable to maintain single engine (OEI) level flight - you could see cleearly the pilot had deployed the flotation gear (although the Mi-14 has a waterborne hull like the H-3).
It then looks like the pilot attempted a water take off - something nearly impossible. We used to try it in the H-46 simulator all the time - usually involves setting the one good engine to somewhere above "military" rated power - or "topping" and using every available piece of horsepower to get the aircraft above translational lift and flying out of the water.
Clearly this pilots training and technique were lacking - way too much forward cyclic - looks like from the rotors coning he was brute forcing it too. Again, bad technique and training.
I did actually do a single engine takeoff from a lake while in the Rag at North Island - it was part of the syllabus back then and even on calm conditions it was a b!tch. Overcoming the friction of the water takes an enormous amount of energy - and you are already overtemping or over torqueing the hell out of your good engine. But that's why the OEM build in conservative safety margins on those normal operating limits!
