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

To compute the maximum forward loaded center of gravity (CG) of an aircraft, it is necessary to use the minimum weights, arms, and moments for items located aft of the forward CG limit. This approach ensures that the calculations take into account the worst-case scenario in terms of weight distribution, which is critical for maintaining aircraft safety and performance.

When the maximum forward CG is being calculated, the goal is to determine how far forward the CG can be positioned based on the weight distribution of the aircraft's load. By using minimum weights for the items located aft of the forward CG limit, you are simulating the scenario where there is the least amount of weight in the aft cargo or passenger area. This results in a CG position that is as far forward as possible since less aft weight allows the CG to shift forward.

This methodology leads to a conservative approach in weight and balance calculations, which is essential for ensuring that the aircraft remains controllable and safe throughout its operational range. Balancing these weights against the items in the forward loading area provides an accurate representation of the aircraft's stability, allowing for informed decision-making regarding loading practices.
