From PeteGillies:
When power is lost to the rotor system, THE MOST IMPORTANT FLIGHT CONTROL IN THE COCKPIT IS THE CYCLIC! It must immediately be brought aft so that the flow of air is upwards through the rotor system.
Total nonsense when applied to the high-hover scenario. A simultaneous lowering of collective and application of FORWARD cyclic to accelerate to a suitable autorotative speed would be a more appropriate response (assuming you had enough height to achieve forward airspeed).
In all cases the cyclic and collective are equally important. Collective lowered to preserve Nr and cyclic to determine a suitable speed and direction towards your nominated landing point.
Slight thread drift I know but I thought it important to quash spurious advice!
