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.
