Moment

The product of a weight multiplied by its arm (distance from the datum), expressed in pound-inches. Moments are used in weight and balance calculations to determine the center of gravity. The total moment of all items loaded in the aircraft (fuel, passengers, baggage) divided by the total weight gives the CG position. Some POHs simplify calculations by using moment divided by a reduction factor (such as 1,000) to produce smaller, more manageable numbers on loading graphs.
