When the CG is within the allowed range, what is its expected effect on controllability?

When the CG is within the allowed range, what is its expected effect on controllability?

• A. The aircraft will be unstable
• B. The CG has no effect on controllability
• C. The CG within the allowed range generally improves controllability
• D. The aircraft cannot fly

Answer: (C)

Center of gravity position determines how stable the airplane is and how effective the control surfaces will be. When the CG is within the prescribed envelope, the aircraft maintains balanced longitudinal stability and control surface effectiveness, so the airplane responds to pilot inputs in a predictable, manageable way. This generally improves controllability because you don’t have to fight excessive elevator forces (too forward CG) or risk instability and oversensitivity (too aft CG). If the CG stays within the allowed range, controllability is enhanced.
