To compute the maximum forward loaded CG, should minimum weights, arms, and moments be used for items located aft of the forward CG limit?

• A. False
• B. True
• C. Not at all
• D. It depends on the aircraft

Answer: (B)

The main idea is that the center of gravity is found from the total weight moments divided by the total weight. To push the CG as far forward as possible (maximum forward loaded CG), you want the aft-side items to contribute as little backward moment as possible. Therefore, you use the smallest possible contributions from those aft items—minimum weight and the corresponding smallest moment (weight times arm). By minimizing the aft items’ impact, the overall CG shifts forward, giving the maximum forward position within the limits. So this approach is correct.
