What is emphasized during an accelerated stall maneuver?

The correct answer highlights that the critical angle of attack is the primary cause of a stall. During an accelerated stall maneuver, the aircraft is deliberately flown into a stall by exceeding the critical angle of attack while maintaining or increasing airspeed. This maneuver demonstrates that a stall can happen regardless of the aircraft’s airspeed as long as the angle of attack is high enough.

Understanding this concept is crucial for pilots because it emphasizes that controlling the angle of attack is vital in preventing stalls, even when flying at higher speeds or loads. The critical angle of attack is the angle at which airflow separates from the wing, resulting in a loss of lift. Therefore, pilots must be aware of maintaining a safe margin below this angle, which is a core principle in stall awareness and recovery training.

Comprehending that stall is about angle of attack rather than merely airspeed helps underscore the importance of proper aircraft management in a variety of flight conditions, enhancing both safety and performance in the air.
