  • Autorotation (helicopter) — Autorotation is the state of flight where the main rotor system of a helicopter is being turned by the action of air moving up through the rotor rather than engine power driving the rotor. The term autorotation can be traced back to a period of… …   Wikipedia

  • Descent (aircraft) — A descent during air travel is any portion where an aircraft decreases altitude, and is the opposite of an ascent or climb. Descents are an essential component of an approach to landing. Other intentional descents might be to avoid traffic, poor… …   Wikipedia

  • autorotation — i. A condition in which a rotor of a helicopter is driven solely by the action of air ascending through its blades rather than by engine power. In helicopters, descending with the power off, air flows in the reverse direction upward through the… …   Aviation dictionary
