When cargo is removed from an aircraft, what generally occurs to the CG if it is taken from behind the CGA?

When cargo is removed from an aircraft, the center of gravity (CG) is affected by the location of the cargo relative to the CGA (center of gravity axis). If cargo is taken from a position behind the CGA, the CG will shift forward. This happens because removing weight from the tail of the aircraft effectively redistributes the aircraft's weight, resulting in a forward movement of the CG.

Furthermore, when the CG moves forward, it impacts the moment calculations as well. The total moments around the CGA will increase since the remaining weight will now have a greater moment arm. This impact is due to the reduced distance from the center of gravity to the points of remaining weight, effectively increasing the overall stability of the aircraft.

Thus, in this particular scenario, the CG does not decrease; instead, it moves forward, leading to an increased stability because of the weight redistribution. Therefore, the correct statement is that the CG moves forward and the total moments increase, which underlines the principle of balance and how inertia plays a role when cargo is removed from different locations on the aircraft.
