Which statement best describes the impact of weight and balance on aircraft performance?

• A. CG within limits is essential for stability, controllability, climb performance, stall characteristics, and landing characteristics.
• B. Weight and balance only influence fuel efficiency.
• C. CG deviations affect nothing about handling.
• D. Weight and balance only matters for cabin comfort.

Answer: (C)

Weight and balance determine how an airplane behaves in flight because the center of gravity location, relative to the wing and tail, governs stability and control effectiveness. When the weight and balance are within the approved limits, the aircraft shows predictable stability, adequate control authority to rotate during takeoff, and proper stall and landing characteristics. If the center of gravity sits too far forward, the airplane becomes more statically stable but harder to maneuver: you’ll feel increased nose-down tendencies, require more elevator input to rotate, and experience higher stall speeds and potentially longer landing distances due to reduced elevator effectiveness. If the center of gravity is too far aft, the airplane becomes less stable and more difficult to control, with a higher risk of abrupt or unrecoverable handling problems, especially during stalls or spins. Weight also affects climb performance, acceleration, and overall efficiency, so heavier loading demands more power and longer takeoff runs and can influence how far you can fly with a given fuel load. In short, keeping the center of gravity within prescribed limits is essential for stable, controllable, and safe climb, stall, and landing behavior.
