Q5 -- A helicopter in forward flight has accumulated blade ice. In the event of autorotation ....

1. RRPM in the cyclic flare will accelerate faster than normal
2. then rate of descent will be higher as the helicopter now has less potential energy
3. safe RRPM may be impossible or difficult to maintain.
4. the rate of descent will be higher, and more collective will be required to maintain RRPM within limits.

Show me the answer
