Throttles in the roof - during one sim session in a 76 level D we were taught, if single pilot (we always were), a tail drive failure in the hover could be handled, if power available, by climbing vertically to height (1,000 suggested), nosing over to gain airspeed, accept side slip, and fly to suitable, spot for auto. It worked in the sim, but in real life? Always had my doubts having seen a fully loaded Huey lose drive in the hover. First question is sim modelling accuracy. John Dixon might give his considered opinion.
Helicopter flying is not inherently dangerous, it's only as dangerous as you want to make it. Three decades with an offshore operator and they never had an accident, nor injured anyone.
