What is the effect of a higher load factor on stall speed?

A higher load factor increases stall speed. The load factor refers to the ratio of the aircraft's lift to its weight, and when the load factor increases, the aircraft experiences greater aerodynamic forces. Essentially, a higher load factor means that the aircraft is experiencing more lift due to a higher angle of attack, which leads to a stall occurring at a higher true airspeed.

Stall speed is the minimum speed at which an aircraft can maintain level flight. When the load factor increases—such as during a steep turn or when pulling up from a dive—the stall speed must also increase to maintain control. This is tied to the fundamental principles of aerodynamics, where an increase in load factor means that the wings must produce more lift to counteract the additional forces acting on the aircraft.

In practical terms, pilots need to be aware that as they maneuver the aircraft and increase load factor—whether due to changes in flight attitudes or during high-performance maneuvers—the stall speed will rise. Awareness of this relationship helps ensure that pilots maintain safe flight margins during flight operations.
