How often should weight and balance calculations be updated?

Weight and balance calculations should be updated whenever there is a change in the aircraft's loading configuration. This is essential because variations in weight distribution can significantly affect the aircraft's center of gravity, stability, and overall performance. Factors such as adding or removing cargo, fuel, passengers, or even making changes to equipment can all alter the aircraft's weight and balance.

By ensuring these calculations are updated with each change, pilots and operators can maintain safety and operational efficiency. This practice is fundamental in aviation, given that an improperly balanced aircraft can lead to handling issues and potential loss of control. Regular updates help ensure compliance with regulatory requirements and enhance safety in flight operations.
