During the flight, what should a pilot monitor to avoid stalling?

Monitoring aileron effectiveness is crucial for a pilot in avoiding stalls during flight. A stall occurs when an aircraft exceeds its critical angle of attack, leading to a loss of lift. Ailerons are the primary control surfaces used to manage roll and maintain coordinated flight. If the ailerons are not functioning effectively, the pilot may lose control of the aircraft, particularly during turns or in turbulent conditions. Thus, ensuring that ailerons are operating properly helps maintain the aircraft’s stability and performance, significantly reducing the risk of stalling.

While flight altitude, fuel levels, and temperature of the aircraft are all important factors in flight safety and performance, they do not directly relate to the management of lift and control that is essential for preventing stalls. Weight and balance, controlled through aileron use, are critical elements to ensure the aircraft can operate safely within its performance envelope.
