Calculate total weight, total moment, and center of gravity from aircraft loading data. This free aviation calculator helps pilots and students practice weight and balance planning and loading awareness.
Enter the weight and arm for each loading station to calculate total weight, total moment, and estimated center of gravity.
| Item | Weight (lb) | Arm (in) | Moment |
|---|---|---|---|
| Empty Aircraft | — | ||
| Front Seats | — | ||
| Rear Seats | — | ||
| Baggage | — | ||
| Fuel | — |
This calculator provides a basic generic loading calculation and does not check whether the result is inside a specific aircraft CG envelope.
A basic weight and balance calculator helps pilots total the aircraft loading, calculate total moment, and estimate the loaded center of gravity.
This is useful during training and planning because it shows how passengers, baggage, fuel, and empty aircraft data combine to affect the final loading condition.
Arm is the horizontal distance from the reference datum to the location of a weight.
Moment is the product of weight and arm. It represents the rotational effect of that weight about the datum.
Center of gravity is the balance point of the loaded aircraft and is found by dividing total moment by total weight.
Not by itself. This calculator gives the basic totals and estimated CG, but you must compare the result against the approved CG envelope and loading limits for your specific aircraft.
