Ballast Fuel

If the operator’s procedures include the use of fuel as ballast, the required amount of ballast fuel should be defined in the DOW (Dry Operating Weight) step.

Once the ballast fuel is defined, the system automatically applies the appropriate correction to:

  • DOW / DOI – Dry Operating Weight / Dry Operating Index
  • AZFW / LIZFW – Actual Zero Fuel Weight / Loaded Index at Zero Fuel Weight

This ensures that the ballast fuel is correctly reflected in the aircraft’s weight and balance calculations.
