Determine the lateral CG by using the data in Figure 10-8 and following these steps: 

1. Add all of the weights:

2. Multiply the lateral arm (the distance between butt line zero and the CG of each item) by its weight to get the lateral offset moment of each item. Moments to the right of BL 0 are positive and those to the left are negative.

3. Determine the algebraic sum of the lateral offset moments.

4. Divide the sum of the moments by the total weight to determine the lateral CG.

The lateral CG is 0.77 inch to the left of BL0. 

## Determining ΔCG Caused by Shifting Weights 

Fifty pounds of baggage is shifted from the aft baggage compartment at station 246 to the forward compartment at station 118. The total airplane weight is 4,709 pounds. How much does the CG shift? 

1. Determine the number of inches the baggage is shifted: (246)(–)(118)(=) 128 

2. Use this formula:

The CG is shifted forward 1.36 inches.

## Determining Weight Shifted to Cause Specified ΔCG 

How much weight must be shifted from the aft baggage compartment at station 246 to the forward compartment at station 118 to move the CG forward 2 inches? The total weight of the airplane is 4,709 pounds. 

1. Determine the number of inches the baggage is shifted:

2. Use this formula:

Moving 73.6 pounds of baggage from the aft compartment to forward compartment shifts the CG forward 2 inches. 

## Determining Distance Weight Is Shifted to Move CG a Specific Distanc 

How many inches aft does a 56 pound battery need to be moved to shift the CG aft by 1.5 inches? The total weight of the airplane is 4,026 pounds. 

Use this formula: 

<img src='content_image/595669.jpg'>

<img src='content_image/595670.jpg'>

Moving the battery aft by 107.8 inches shifts the CG aft 1.5 inches.
