Which of the following is not a factor in weight and balance calculations?

Weight and balance calculations are critical in aviation for ensuring that an aircraft operates safely within its load limits. The calculations assess how the weight of the aircraft, including all its contents, is distributed. This distribution impacts the aircraft’s center of gravity, which is crucial for maintaining stable flight.

Fuel load, cargo weight, and occupant weight are all essential factors in these calculations because they directly contribute to the total weight of the aircraft and its balance. Changes in any of these elements can shift the center of gravity, which can affect performance and safety during flight.

In contrast, weather conditions do not directly factor into weight and balance calculations. While weather can impact flight operations and safety, it does not alter the physical weight or distribution of the aircraft’s load. Weather conditions are more relevant to flight planning and operational considerations, rather than the specific calculations of weight and balance prior to a flight.
