What data is required to perform a weight and balance calculation?

• A. To maximize load.
• B. To ensure total weight and center of gravity are within permitted limits.
• C. To determine color of aircraft.
• D. To decide engine type.

Answer: (B)

Weight and balance calculations hinge on knowing how much weight is on board and where that weight is located. To perform them, you need the airplane’s empty weight data (including its moment), plus the weights of all items added (pilot, passengers, baggage, fuel) and each item’s arm (or moment). By multiplying each item’s weight by its arm, you get moments, which you add together to get the total moment. Dividing this total moment by the total weight gives the center of gravity. The result is then checked against the permitted forward and aft CG limits to ensure safe balance. Data like color or engine type doesn’t affect weight and balance, so they aren’t relevant to the calculation.
