If you are given a CG at 77.6 in and the aft limit is 78 in, how far can you move the CG aft before reaching the limit?

If you are given a CG at 77.6 in and the aft limit is 78 in, how far can you move the CG aft before reaching the limit?

• A. Approximately 0.4 inches toward the aft limit.
• B. Approximately 2 inches.
• C. Approximately 1 inch.
• D. Approximately 0.4 inches toward the aft limit.

Answer: (D)

The distance you can move the CG aft is simply the difference between the aft limit and the current CG. If the aft limit is 78 inches and the current CG is at 77.6 inches, the remaining movement toward the aft limit is 78 - 77.6 = 0.4 inches. So you can move the CG aft by about 0.4 inches before you reach the limit; any more would exceed the allowable aft CG.
