When computing the maximum forward loaded CG of an aircraft, which weights should be used?

When computing the maximum forward loaded center of gravity (CG) of an aircraft, it is essential to use the minimum weights, arms, and moments for items located forward of the forward CG limit. This approach ensures that you are considering the lightest potential load configurations that still maintain compliance with the aircraft's performance specifications and stability requirements.

Focusing on minimum weights for items positioned forward of the forward CG limit is crucial because these items have a direct impact on moving the CG toward the front of the aircraft. By assessing the minimum weights, you ensure that the calculations reflect the most favorable (i.e., forward) weight scenario. As the CG must remain within certified limits for safe operation, accurately calculating using these minimum weights helps maintain compliance and safety.

In contrast, evaluating items located aft of the forward CG limit or using average weights does not provide a precise assessment of the worst-case scenario regarding forward loading. This would not allow for the correct determination of how loading configurations affect the CG, potentially leading to unsafe operational conditions.
