If an item located aft of the aircraft's CG is removed, how will the CG change?

When an item located aft of the aircraft's center of gravity (CG) is removed, the CG will move forward in proportion to the weight of the item. This is because the removal of weight from the aft section reduces the overall arm distance from the reference point, effectively shifting the balance point closer to the forward section of the aircraft.

The CG is calculated based on both the weight and the distance from the reference point; thus, when a weight is removed from the rear, the overall moment reduces, which in turn affects the position of the CG. Moving the CG forward in response to removing an aft weight is a fundamental concept in weight and balance calculations, ensuring that the aircraft remains within its specified limits for safe operation.

In summary, the removal of a weight from behind the CG decreases the total rearward moment, causing the CG to shift forward, which is essential for maintaining proper balance and performance of the aircraft.
