What does weight and balance determine in relation to flight performance?

• A. It determines the center of gravity within published limits; helps ensure stability and performance.
• B. It determines the flight crew rest requirements.
• C. It determines the color of the interior.
• D. It determines the weather forecast.

Answer: (C)

Weight and balance is about where the aircraft’s center of gravity sits relative to published limits. The location of the CG directly influences stability and controllability, which in turn affects flight performance. If the CG is too far forward or aft, handling changes—pitch response, elevator authority, stall characteristics, and the required trim—leading to changes in takeoff and landing distances and overall maneuverability. Keeping the CG within the specified limits ensures predictable, safe performance and stable flight behavior. The other items listed—rest requirements, interior color, and weather forecasts—aren’t determined by weight and balance.
