If you know of a different situation other than a tail rotor problem where you close down both engines in flight, I'd like to know!
@SS
Yes, I agree with you...when you train autorotations on EC135 in Eurocopter factory, they tell you that you do that for, more or less, only one case - fenestron failure! In that case, you must put both eng to IDLE, and finish the flight with auto. If you enter last 100 ft with less than 60 KIAS, more or less, you will crash!
