Calculate aviation moment using weight and arm. This free aviation calculator helps pilots and students with weight and balance planning and loading analysis.
Enter weight and arm to calculate total moment. The calculator also shows moment divided by 100 and 1000 for aircraft documents that use scaled moment values.
This calculator is useful for weight and balance planning, training, and loading analysis.
In aviation weight and balance, moment is the product of a weight and its arm. It describes the rotational effect of that weight about the aircraft reference datum.
Pilots use moment values to help determine center of gravity and confirm whether a loading configuration is within the aircraft’s approved limits.
Arm is the horizontal distance from the reference datum to the location of the weight.
In aviation weight and balance, moment is commonly expressed as pound-inches when weight is in pounds and arm is in inches.
This keeps moment values smaller and easier to read in loading tables, charts, and forms.
No. This calculator is a planning aid. Pilots should always use approved aircraft weight and balance data, loading procedures, and published limitations.
