Changes in the center of pressure of a wing affect the aircraft's

• A. Aerodynamic balance and controllability
• B. Aerodynamic stability in yaw
• C. Lift generation
• D. Drag coefficient

Answer: (A)

The center of pressure is the point where the wing’s lift can be considered to act, and its position determines the pitching moment produced about the aircraft’s center of gravity. When the center of pressure shifts during flight (due to angle of attack changes or configuration changes like flaps), the moment about the CG changes as well. This alters the aircraft’s static stability in pitch—whether it tends to return to level after a disturbance—and the amount of elevator or other control input needed to trim or maneuver. In short, shifts in the center of pressure change the balance of moments that keep the airplane steady and controllable in flight. It’s not primarily about changing lift magnitude or drag; it’s about how the lift-induced moment affects pitch stability and how easily the aircraft can be controlled.
