Well, the AV-8B wouldn't have it because it is not a 
helicopter! Autorotation is an emergency maneuver
used in helicopters: the downward motion of the helicop-
ter is used to drive the rotor around by giving the rotor
blades a negative pitch angle. The tail rotor is also 
decoupled. It is the helicopter equivalent of gliding.

Autorotation is used when the engine quits.
