Which statement best describes the center of gravity's effect on flight?

• A. It influences balance and affects stability, controllability, and performance
• B. It only affects takeoff speed
• C. It only affects landing distance
• D. It has no effect on flight characteristics

Answer: (A)

The center of gravity location sets how weight is distributed along the airplane’s longitudinal axis, which directly determines balance in flight. That balance influences longitudinal stability—how the aircraft tends to stay in trim or return to it after a disturbance—and controllability, which is how effectively the pilot can pitch the aircraft with the elevator and other controls. It also touches overall performance, since weight distribution affects maneuverability, handling qualities, and how the airplane responds to control inputs during all phases of flight. A forward CG tends to make the airplane more stable in pitch but harder to rotate and less responsive to control inputs, while an aft CG makes it more maneuverable but less stable and more sensitive to disturbances. Because the CG impacts balance, stability, controllability, and performance, the statement captures the essential effect of CG on flight. The other options are too narrow or false, since CG affects more than just takeoff or landing performance, and it certainly does influence flight characteristics.
