How does load factor affect stall speed?

Load factor plays a critical role in determining stall speed. Stall speed is the minimum speed at which an aircraft can maintain controlled flight. When the load factor increases, due to maneuvers such as turns or variations in weight, the aircraft experiences more lift than at a standard load factor.

The stall speed increases because stall is defined as the angle of attack at which the wings can no longer produce enough lift to support the aircraft's weight. At higher load factors, the wings need to produce significantly more lift to counteract the increased weight caused by the load factor. As a result, the aircraft must fly at a higher speed to achieve the necessary angle of attack before reaching the critical angle where stall occurs. Therefore, with an elevated load factor, stall speed increases, leading to the conclusion that it raises the stall speed.

This understanding is important for pilots to ensure safe flight operations, particularly in situations that may increase the load factor, like sharp turns or heavy maneuvers.
