Weight and balance calculations determine where the aircraft will balance in flight by locating the center of gravity. This is found by adding up all items’ moments (each weight multiplied by its distance from the datum) and then dividing that total by the aircraft’s total weight. The resulting CG location shows where the airplane would balance along the longitudinal axis, typically expressed as an distance from the datum. Keeping the CG within the approved forward and aft limits is essential for proper controllability and stability; if it falls outside, you adjust payload, fuel, or baggage to move the CG. Other metrics like overall length, fuel efficiency, or wing loading aren’t obtained from summing weights and moments; they relate to geometry or performance rather than balance.
