This weight and balance calculator helps you determine the optimal load distribution for safe and efficient operations.

## How to Use the Aircraft Weight and Balance Calculator

To use this calculator, input the following values:

**Aircraft Weight:**The empty weight of the aircraft in pounds.**Fuel Weight:**The total weight of the fuel in pounds.**Pilot and Passenger Weight:**The combined weight of the pilot and passengers in pounds.**Cargo Weight:**The weight of the cargo in pounds.**Empty Arm:**The arm length from the datum to the empty center of gravity in inches.**Fuel Arm:**The arm length from the datum to the fuel tanks in inches.**Pilot and Passenger Arm:**The arm length from the datum to the pilot and passenger seats in inches.**Cargo Arm:**The arm length from the datum to the cargo area in inches.

Once all fields are filled in, click on the “Calculate” button to obtain the result. The result will display the calculated center of gravity (CG) in inches.

## How it Calculates the Results

The calculator computes the moments for each load component (aircraft, fuel, pilot and passengers, and cargo) by multiplying their weights by their respective arms. The total moment is the sum of all the individual moments. The total weight is the sum of all individual weights. The center of gravity (CG) is then determined by dividing the total moment by the total weight:

*CG = Total Moment / Total Weight*

## Limitations

This calculator assumes that all entered values are accurate and that the units are consistent (pounds for weight and inches for arm lengths). Errors in input values will result in incorrect calculations. Always cross-check with aircraft-specific data and consult the aircraft manual for precise calculations.
