Type of Fuel

	Weight per Volume (specific weight)

weight per volume (specific weight) based on temperature [^oC] [^oF] Note: results for weight per volume are typically accurate up to one decimal point only. Due to the inherent variability of fuels even the same type of fuel may vary greatly depending on its origin. The figures provided here are a very rough estimate. Values based on FAA-H-8083-1A, Aircraft Weight and Balance Handbook Chart, page 7-13.

Load Examples

Light Aircraft (twin piston, four seats)
Commuter Aircraft
Light Helicopter (piston, two seats)

      Instructions: Select type of fuel (if appropriate), then begin by entering the weight and balance information for the longitudinal axis. Remember to
      select the appropriate calculation mode for each row before typing the information for that row. When entering a fuel quantity, you may use volume
      quantities by checking the fuel box in the desired row. This will then cause the sheet to calculate fuel weight based on the fuel selected and the weight
      per volume value. If you are entering the fuel weight directly then you do not need to check the fuel box. The description box is completely ignored
      in the computations. Use this box to describe the content of the row entered. Once the longitudinal axis is entered, the lateral axis can be entered if
      this is desired, otherwise ignore this section. The lateral axis is generally used for weight and balance calculations for helicopters.


CG Shift

Weight Shifted	[lbs]	[kg]	[oz]	[g]
Distance Shifted	[in] - L / + R	[m] - L / + R	[ft] - L / + R	[cm] - L / + R
Total Weight	[lbs]	[kg]	[oz]	[g]
Shift in CG (ΔCG)	[in] - L / + R	[m] - L / + R	[ft] - L / + R	[cm] - L / + R

Enter any three fields then press "Eval" on any remaining field for that field's result.


CG % Aft of MAC

Distance Aft of LEMAC	[in]	[m]	[ft]	[cm]
LEMAC	[in]	[m]	[ft]	[cm]
CG % Aft of LEMAC	[%]

    Enter any two fields then press "Eval" on any remaining field for that field's result.

    Abbreviations:     MAC = Mean Aerodynamic Cord
                              LEMAC = Leading Edge Mean Aerodynamic Cord


CG from Datum

LEMAC	[in]	[m]	[ft]	[cm]
MAC	[in]	[m]	[ft]	[cm]
CG % Aft of LEMAC	[%]
CG distance from Datum	[in]	[m]	[ft]	[cm]

    Enter any three fields then press "Eval" on any remaining field for that field's result.

    Abbreviations:     MAC = Mean Aerodynamic Cord
                              LEMAC = Leading Edge Mean Aerodynamic Cord


Ballast

Weight of Aircraft without Ballast	[lbs]	[kg]	[oz]	[g]
Distance Out of Limits	[in] - L / + R	[m] - L / + R	[ft] - L / + R	[cm] - L / + R
Distance Between Ballast and Desired CG	[in] - L / + R	[m] - L / + R	[ft] - L / + R	[cm] - L / + R
Ballast Weight	[lbs]	[kg]	[oz]	[g]

Enter any three fields then press "Eval" on any remaining field for that field's result.
Note: "Distance Out of Limits" and "Distance Between Ballast and Desired CG" must have opposite signs for balancing to be possible.


Cargo Pallet Load

Length of Pallet (L)	[in]	[m]	[ft]	[cm]
Width of Pallet (W)	[in]	[m]	[ft]	[cm]
Loaded Pallet Weight	[lbs]	[kg]	[oz]	[g]
Floor Load	[lbs/in²] [kg/in²] [oz/in²]	[lbs/m²] [kg/m²] [oz/m²]	[lbs/ft²] [kg/ft²] [oz/ft²]	[lbs/cm²] [kg/cm²] [oz/cm²]

Enter any three fields then press "Eval" on any remaining field for that field's result.
