The Maximum Zero Fuel Mass is:
  • A
    tabulated in the Flight Manual against arguments of airfield elevation and temperature.
  • B
    governed by the traffic load to be carried.
  • C
    governed by the CG limits.
  • D
    a structural limit listed in the Flight Manual as a fixed value.

Maximum zero fuel mass (MZFM) is the maximum mass allowed before usable fuel and other specified usable agents (engine injection fluid, and other consumable propulsion agents) are loaded in defined sections of the aircraft as limited by strength and airworthiness requirements defined by the manufacturer and listed in the flight manual as fixed value.

The MZFM is a structural limit based on the bending moments of the wing root.
