Question

During an aircraft turnaround, which specific weight and balance document must be finalized to confirm that the aircraft’s center of gravity remains within certified safety limits for takeoff?

Accepted Answer

The specific document that must be finalized during an aircraft turnaround to confirm that the center of gravity remains within safety limits is the Load Sheet. A Load Sheet is a document that records the final distribution of weight on the aircraft, including passengers, cargo, fuel, and the aircraft itself. The center of gravity is the theoretical point through which the total weight of the aircraft is assumed to act, and it must be positioned within a predefined range to ensure the aircraft remains stable and controllable during flight. To create a Load Sheet, ground personnel calculate the total weight of all items loaded and their specific locations relative to a reference point on the aircraft known as the datum. By multiplying each weight by its distance from the datum, they determine the moment, which represents the rotational force exerted by that weight. Summing these moments and dividing by the total aircraft weight provides the precise location of the center of gravity. If the resulting center of gravity falls outside the certified limits, the aircraft could become difficult or impossible to control, leading to potential stalling or loss of pitch authority. Finalizing the Load Sheet confirms that all variables have been accounted for and that the aircraft is legally and physically safe for takeoff.
