Estimate moment change and center of gravity shift using weight moved, distance moved, and total aircraft weight. This free aviation calculator helps pilots understand loading changes during weight and balance planning.
Enter the weight moved, the distance it is moved, and the total aircraft weight to estimate moment change and center of gravity shift.
This calculator estimates only the effect of moving a known weight. It does not replace a full weight and balance calculation.
A weight shift and CG estimator helps pilots understand how moving baggage, passengers, equipment, or other load items changes the aircraft center of gravity.
It works by calculating the moment change caused by shifting a known weight and then dividing that change by the total aircraft weight to estimate the resulting CG movement.
In this calculator, a positive shift means the center of gravity moves aft because the weight was moved toward the rear of the aircraft.
A negative shift means the center of gravity moves forward because the weight was moved toward the front of the aircraft.
It can be used as a general training aid, but real aircraft loading decisions must always use the approved weight and balance data and limitations for that aircraft.
No. This calculator is not a substitute for approved loading forms, POH or AFM data, or published CG envelopes.
