If the empty weight CG of an airplane is within limits, what is required?

When the empty weight center of gravity (CG) of an airplane is within limits, no further calculations are necessary for the empty weight condition. This indicates that the aircraft is properly balanced at its current configuration without exceeding any specified CG limits.

In practice, maintaining the empty weight CG within the prescribed limits is crucial for ensuring safe flight characteristics, as it affects the aircraft's stability and control. It means that the airplane, in its current unladen state, does not require any adjustments for CG manipulation.

While monitoring and verifying weight limits and CG extremes can be important under different operational conditions or when new weights are added (like cargo or passengers), they are not necessary just because the empty weight CG is already within specified parameters. Therefore, recognizing that further calculations or notifications about CG adjustments are unnecessary streamlines the workflow and ensures efficient compliance with safety standards.
