What is the primary purpose of weight and balance calculations for flight safety?

• A. To determine the color of the aircraft.
• B. To monitor air traffic density.
• C. To ensure stability and controllability and prevent CG from exceeding limits.
• D. To decide on in-flight entertainment.

Answer: (C)

Weight and balance calculations focus on where the aircraft’s weight is distributed relative to a reference point, ensuring the center of gravity stays within the approved limits. The primary purpose is to ensure stability and controllability and prevent the CG from exceeding those limits. When the CG is too far forward, the airplane becomes more nose-heavy, increasing stability but reducing elevator authority, which can make rotation, pitch control, and flare harder. If the CG is too far aft, the aircraft can become less stable and harder to control, with reduced pitch authority and a higher risk of unsafe handling characteristics. Keeping the CG within the certified envelope also helps maintain safe stall behavior and prevents excessive structural loads during flight. Other options don’t impact safety-critical loading and handling in the same way.
