How do you calculate the center of gravity (CG) for an aircraft?

To calculate the center of gravity (CG) of an aircraft, the correct approach involves dividing the total moment by the total weight. This method utilizes the relationship between the moments (which represent the distribution of weight at various points along the aircraft) and the total weight of the aircraft to find the CG, which is the point where the aircraft balances.

The total moment is calculated by multiplying the weight of each component by its distance from a reference point, typically the nose of the aircraft. Summing these products gives you the total moment. Once you have the total moment, dividing it by the total weight effectively gives you the distance from the reference point to the CG. This calculation is crucial for ensuring the safe operation of the aircraft, as the CG location affects stability and control.

Understanding this process is essential for maintenance personnel, as properly calculating CG helps ensure that the aircraft is within its safe operating limits, enabling optimal performance during flight.
