What effect does an increased load factor have on an aircraft during an approach to a stall?

1. Stalls at a lower airspeed

2. Stalls at a higher airspeed

3. Increases lift dramatically

4. Reduces stall speed

The correct answer is: Stalls at a higher airspeed

An increased load factor during an approach to a stall results in the aircraft stalling at a higher airspeed. Load factor refers to the amount of lift that an aircraft must generate to support its weight during maneuvers, particularly in turns. As the load factor increases, generally due to increased bank angle or changes in weight distribution, the aircraft experiences more G-forces. When the load factor rises, the aircraft must achieve a higher angle of attack to maintain level flight. This is because the wings need to produce more lift to counteract the increased weight from the load factor. Consequently, the stalling angle of attack, which is the angle at which the wings can no longer maintain lift, does not change. However, since the aircraft now needs to reach a higher angle of attack to generate enough lift due to the increased load factor, it will reach stall conditions at a higher airspeed than it would at a lower load factor. This phenomenon is particularly crucial during maneuvers such as turns or abrupt changes in flight path, where the load factor can change significantly. Understanding this relationship helps pilots maintain better control of the aircraft and avoid stalling in challenging scenarios.
