What is autorotation and when would it be used in air assault operations?

• A. A high-speed maneuver to outrun ground fire.
• B. A controlled descent without engine power allowing a safe landing in an emergency or training scenario.
• C. A method to increase lift at high altitude.
• D. A stealth approach technique.

Answer: (B)

Autorotation is a controlled descent in which the rotor continues to turn and generate lift without engine power, using the relative wind to keep the rotor spinning. This allows a safe landing when the engine fails or during training to practice emergency procedures. In air assault operations, pilots train and plan for autorotation so they can land safely in unprepared zones if power is lost, or during drills to maintain proficiency. The other ideas don’t fit: outrunning ground fire isn’t about rotor physics, increasing lift at high altitude isn’t about an emergency descent, and stealth approaches are separate tactics.
