What is the effect of load factors on an aircraft's stall speed?

When discussing the impact of load factors on an aircraft's stall speed, it's important to understand the relationship between the two. Stall speed is the minimum speed at which an aircraft can be flown while maintaining controlled flight. This speed is influenced by the aircraft's weight and the load factor, which is the total lift divided by the weight of the aircraft.

As load factors increase—such as during maneuvers that involve turns or when the aircraft is under high g-forces—the amount of lift that must be produced to maintain controlled flight also increases. Consequently, in order to avoid stalling, the aircraft must be flown at a higher speed. This increase occurs because the stall speed is proportional to the square root of the load factor. Therefore, when the load factor rises, so does the stall speed.

This principle is essential for pilots to understand, as it affects how they handle the aircraft during flight. Recognizing that higher load factors will lead to an increased stall speed helps ensure safer operation during various maneuvers and phases of flight where the aircraft may be subjected to greater forces.
