A revenue flight is to be made by a jet transport. The following are the aeroplane structural limits:

Maximum Ramp Mass: 69 900 kg
Maximum Take-off Mass: 69 300 kg
Maximum Landing Mass: 58 900 kg
Maximum Zero Fuel Mass: 52 740 kg
Dry Operating Mass: 34 900 kg
Trip Fuel: 11 800 kg
Taxi Fuel: 500 kg
Contingency and final reserve fuel: 1 600 kg
Alternate Fuel: 1 900 kg
Take-off and Landing Mass are not performance limited. The maximum Traffic Load (TL) that can be carried is:
  • A
    19 500 kg
  • B
    19 100 kg
  • C
    17 840 kg
  • D
    19 200 kg

To get the takeoff mass will be smallest of:

1- MSTOM: 69300 kg
2- MLM + trip fuel: 58900 + 11800 = 70700 kg
3- MZFM + takeoff fuel = 52740 + 11800 + 1600 + 1900 = 68040 kg (smallest number)

Maximum traffic load = Takeoff mass — (Dry operating mass + Fuel onboard)
Maximum traffic load = 68040 — (34900 + 11800 + 1600 + 1900) = 17840 kg
