How is the Center of Gravity (CG) of an aircraft determined?

The Center of Gravity (CG) of an aircraft is calculated by dividing the total moments by the total weight. To determine the moment, one must multiply each individual weight by its corresponding arm (the distance from a reference point, typically the nose or another defined point on the aircraft). The sum of all these individual moments provides the total moment for the aircraft. This total moment is then divided by the total weight, yielding the location of the CG relative to the reference point.

This method is essential because it accurately reflects the distribution of weight throughout the aircraft, allowing for safe and efficient flight operations. The location of the CG affects the aircraft's stability, control, and overall performance, making this calculation critical in aviation operations.

Understanding this process is vital, as it directly impacts flight safety and efficiency. While the other choices may involve concepts related to weight or distribution, they do not correctly describe the mathematical relationship needed to determine the CG accurately.
