What are the basic elements of a preflight weight and balance check?

• A. Aircraft weight, center of gravity, and loading limits vs allowable CG range
• B. Engine horsepower and propeller type
• C. Fuel quantity and oil level
• D. Exterior color and number of seats

Answer: (A)

Weight and balance focuses on making sure the airplane is loaded within its published limits so performance and controllability are predictable. The basic elements are the aircraft’s weight, the center of gravity location, and the loading limits versus the allowable CG range. Total weight includes everything on board—crew, passengers, baggage, fuel, and the basic empty weight—and is used to verify you’re under the maximum gross weight and other weight limits. The center of gravity is where the total weight effectively acts along the longitudinal axis; if the CG is too far forward or aft, it can make the aircraft difficult to control, affect stability, and alter stall characteristics. The loading limits versus the allowable CG range are the published boundaries that define acceptable combinations of weight and CG; you must ensure the computed weight and CG lie within this envelope before flight. Other items like engine horsepower or propeller type aren’t part of the weight-and-balance check, and while fuel and oil are included in the weight calculation, exterior color and number of seats don’t impact weight and balance.
