How does an increase in load factor affect stall speed?

• A. Stalling speed decreases
• B. Stalling speed remains the same
• C. Stalling speed increases
• D. Stalling speed fluctuates based on altitude

Answer: (C)

An increase in load factor directly impacts stall speed, causing it to increase. Load factor can be understood as the ratio of the lift produced by the wings to the weight of the aircraft. When an aircraft maneuvers, such as during turns or rapid altitude changes, the load factor increases, which means that the aircraft needs to generate more lift to maintain altitude. As load factor rises, the stall speed also rises according to the square root of the load factor. This relationship is critical because stall speed, which is the minimum speed at which an aircraft can maintain controlled flight, is directly influenced by the aerodynamic forces acting upon it. Higher load factors mean that a greater amount of lift is required to keep the plane flying, which in turn necessitates a higher airspeed to avoid stalling. This principle is important for pilots to understand, as it emphasizes the need to be aware of their aircraft's load factor during various flight conditions. Recognizing this relationship helps in making better judgments during flight operations, particularly in maneuvering situations where load factors tend to increase.
