Army Aviation Captain's Career Course (AVC3) Entrance Practice Exam

Autorotation is the state of flight in which the rotor system remains turning and provides lift without engine power, allowing a controlled descent and safe landing when power is unavailable. The rotor blades are driven by the upward flow of air through the rotor as you descend or move through the air, not by the engine. Pilots manage rotor RPM and lift during this condition to ensure a controlled approach and touchdown, even with an engine failure or power loss.

This isn’t about aerobatics, a landing gear system, or a ground shutdown procedure, which is why those descriptions don’t fit.
