Which statement best describes baseline weight in a CG problem?

• A. It equals the sum of basic empty weight and payload.
• B. It equals only basic empty weight.
• C. It equals only payload weight.
• D. It equals total fuel weight.

Answer: (A)

Baseline weight is the fixed part of the aircraft’s weight used as the starting point for a CG calculation. It combines basic empty weight with the payload, because these are the components that remain in the configuration regardless of how much fuel is on board. Fuel weight can vary, and its moment is handled separately when you determine the overall center of gravity, since fuel distribution can change with flight conditions. If you used only the basic empty weight, you’d ignore the impact of the payload on balance; if you used only the payload, you’d miss the aircraft’s inherent structure weight; if you used total fuel weight, you’d misrepresent the reference point for balance. So the baseline is BEW plus payload, providing the correct fixed reference before adding fuel and any other variable items.
