SETTING UP WEIGHT & BALANCE

Use the technical data from your aircraft's operating handbook to enter the information required for performing weight and balance calculations:

• Select the weight units from the drop-down list.
  Note: If you are using the Advanced template, make sure the units selected here match the units in the Advanced Data tables.
• Enter the maximum weight limits for ramp, take-off (MTOM), landing (MLDGM) and zero fuel (MZFM).
  These are the critical values for W&B calculations so make sure they are consistent with the data in your Pilot's Operating Handbook (aircraft manual).
• Enter the weight and arm (moment) for each area.
  Amend the descriptions of the areas to suit the most common loading arrangement for your aircraft.
  Click + Add More to add further areas as required for your aircraft.
• Enter the fuel balance weight and arm data, which describes how the aircraft's weight is re-distributed during the flight as the fuel is consumed.
  At least two points are needed, for the minimum and maximum fuel loads. Click + Add More to add further points if the consumption of fuel significantly affects the aircraft's centre of gravity.
• Enter the weight and arm data for the aircraft's weight and balance envelope, which sets the safe limits for the aircraft during flight.
  Click + Add More to add further points as required for your aircraft.
• Enter the measurements for the mean aerodynamic chord (MAC) of your aircraft's wings to allow the software to calculate the %MAC at different stages of the flight.
  %MAC indicates whether the aircraft's centre of gravity is within the required limits for optimum stability. It can be calculated from the actual measurements (LeMAC = leading edge MAC) if these are known. Some aircraft manufacturers provide a method to convert %MAC into an Index value, expressed as an offset value and multiplication factor. Consult your Pilot's Operating Handbook (aircraft manual) for further details.
