What factors contribute to an increase in stall speed?

• A. Higher weight and a smaller flap setting
• B. Lower weight and greater thrust
• C. Increasing bank angle and a forward CG shift
• D. Decreased load factor and aft CG shift

Answer: (C)

Stall speed is the minimum airspeed at which an aircraft can maintain level flight. Factors that influence stall speed include weight, configuration, load factor, and center of gravity. An increase in bank angle results in a higher load factor, which directly raises stall speed. As the aircraft banks, the lift required to counteract the increased weight component acting downward due to the bank increases, thus demanding a higher airspeed to generate adequate lift. Similarly, if the center of gravity shifts forward, it can also increase the stall speed due to the altered aerodynamic characteristics and increased control forces required to maintain level flight. Both of these factors – an increase in bank angle and a forward shift in the center of gravity – lead to a significant increase in stall speed compared to level flight, where requirements for lift and control forces are less stringent.
