What happens if the empty weight CG does not fall within the specified range?

When the empty weight center of gravity (CG) does not fall within the specified range, it indicates that the aircraft's balance is not within acceptable limits for safe operation. This situation necessitates a forward or aft CG check. A proper check involves determining the weight and balance of the aircraft with the current configuration, ensuring it is loaded correctly, and assessing whether any adjustments are needed to correct the CG position.

Performing this check may involve redistributing cargo, fuel, or passengers to bring the CG within the allowable limits. Having the CG in the appropriate range is crucial for maintaining stability and control during flight, preventing potential safety issues. While grounding the aircraft until repairs could be an option in some circumstances, it’s not the only immediate step and does not directly address the CG issue. Therefore, the correct course of action is to conduct a forward or aft check to resolve the imbalance.
