What is the formula to calculate weight and balance?

The formula to calculate weight and balance in aviation is typically represented by the relationship involving moments and weights. In this context, the correct formula indicates that the total moments divided by the total weight gives an indication of the center of gravity, often represented as the "W+B" or Weight and Balance calculation.

In this equation, "Moments" refers to the product of weight and distance from a reference point (usually the datum), which helps to establish where the center of gravity of the aircraft is located. By dividing the total moments by the total weight, you effectively determine the center of gravity position relative to the reference point, which is critical for ensuring safe aircraft operation.

Correctly applying this formula ensures that the aircraft remains within the allowable center of gravity limits during flight, as improper weight distribution can adversely affect performance and safety. Understanding and using this relationship is fundamental in the context of aviation weight and balance calculations.
