What action contributes to an increase in stall speed during a maneuver?

Increasing the angle of attack directly contributes to an increase in stall speed during a maneuver. The stall speed of an aircraft is defined as the minimum speed at which the aircraft can maintain controlled flight. When the angle of attack is increased, the lift produced by the wings initially increases as well; however, it reaches a critical point—called the critical angle of attack—beyond which the airflow begins to separate from the wing, leading to a stall.

As the angle of attack increases, the aircraft must fly at a higher true airspeed to maintain the required lift, thereby increasing the stall speed. This is particularly important to consider during maneuvers that involve sharp turns or climbs where the angle of attack can easily exceed safe limits.

Understanding the relationship between angle of attack and stall speed is crucial for pilots, as it emphasizes the need for maintaining awareness of their flying environment and ensuring they do not exceed the aircraft's stall parameters during operations.
