Autorotation not only works very well, but demonstrating the ability to make an autorotation landing is a pre-requisite for a helicopter pilot certificate. There is a very large amount of energy in a spinning heli blade, and the principle of autorotation is to maintain that energy while using the drag of the blades to maintain a steady (albeit high) rate of descent until just before landing, when the rotational energy is used to decelerate the heli. -- +---------------------------------------------------------------------------+ | Robert J.
