How is the Center of Gravity of the aircraft calculated?

The calculation of an aircraft's Center of Gravity (CG) is performed by dividing the total moments by the total gross weight. The moment is a measure of the rotational force about a point, and in the context of aviation, it refers to the weight of all loaded items in the aircraft multiplied by their respective distances from a reference point, usually the aircraft's datum line.

To find the CG, you take the sum of these moments (which takes into account both the weight and the position of each loaded item) and divide that by the total weight of the aircraft. This gives a precise point in the aircraft where the total weight is considered to act, which is critical for maintaining the aircraft's stability and control during flight. Proper CG calculations are essential for safe aircraft operations, as they affect the handling, performance, and overall safety of the aircraft.

Although other choices contend with elements related to the aircraft instead of focusing on how CG is specifically calculated using moments, they do not provide the established formula used in aviation for determining the Center of Gravity.
