Twin engine helicopter performance
I have looked but are still baffled with a number of elementary and perhaps naive questions regarding twin engine helicopter performance. May I state them simply?
1. Can such a machine sustain its own weight on one?
2. Can it land and takeoff on one?
3. Can it land and take off one one plus some payload?
4. Can it land and take off on one at MAUW?
My reasoning is that if 1 to 4 are true then the second engine is purely in place for safety and more speed.
Put me right someone.
Thanks
