What could bring the CG of an aircraft with a weight of 3,700 pounds at 92.5 inches into the allowable range of 90.0 to 92.0 inches?

To determine what would bring the center of gravity (CG) of the aircraft into the allowable range of 90.0 to 92.0 inches, it is important to understand how weight and arm distances interact to affect CG. The current CG is at 92.5 inches, which is above the upper limit of the acceptable range. Achieving a CG within the specified limits can involve either removing weight or shifting it rearward in some configurations.

In this scenario, you have a weight of 3,700 pounds at a CG of 92.5 inches. The aim is to find out how much weight needs to be removed to bring the CG down to within the range of 90.0 to 92.0 inches.

For calculation:

1. The distance the CG needs to move down is 0.5 inches (from 92.5 to 92.0).

2. Knowing that the relationship of weight removal and movement is linear, you can calculate the needed weight to remove.

3. Using the formula that accounts for weights and moments (Weight x Arm = Moment), you can set up equations to determine how much weight removal affects the overall CG.

Based on the math involved, removing 15 pounds will effectively create
