What is the purpose of weight and balance data in flight planning?

• A. To determine takeoff distance, climb performance, stability, and controllability.
• B. To determine fuel type to be used.
• C. To decide on the airspeed indicator type.
• D. To calculate flight time only.

Answer: (B)

Weight and balance data tells you how loading affects the airplane’s weight, center of gravity, and the resulting handling and performance. When weight and CG are known and kept within limits, you can anticipate how the aircraft will behave in takeoff, climb, and overall stability, ensuring controllability and safe maneuvering. The number and location of weight affect takeoff distance and climb performance because more weight or a CG farther from the ideal range changes lift, elevator authority, and rate of climb. Fuel type, airspeed indicator type, and simply calculating flight time are not determined by weight and balance data, so the most relevant purpose is assessing how loading influences performance and control.
