During dispatch calculations, you want to calculate the maximum possible Traffic Load and carry as a minimum 13 800 kg of Block Fuel.

Determine the Allowed Traffic Load for your flight, given:

Allowed Take-off Mass: 71 240 kg
Maximum Zero Fuel Mass: 56 380 kg
Dry Operating Mass: 40 561 kg
Actual Traffic Load: 14 367 kg
Taxi Fuel: 274 kg

Assume NO restrictions on the Landing Mass.

  • A

    1 452 kg

  • B

    2 786 kg

  • C
    15 819 kg
  • D

    17 153 kg

Traffic Load (TL) is the difference between the actual take-off mass and the Operating Mass (OM). Operating Mass (OM) = DOM + Fuel (but without the Traffic Load)

(1) The actual take-off mass is the lowest of:

  • Allowed Take-off Mass = 71 240 kg

  • MZFM + (block fuel - taxi fuel) = 56 380 kg + (13 800 kg - 274 kg) = 69 906 kg

(2) Allowed Traffic Load = TOM - OM:

  • OM = DOM + (Block Fuel - Taxi Fuel)
    OM = 40 561 kg + (13 800 kg - 274 kg) = 54 087 kg

  • Allowed Traffic Load = TOM - OM
    Allowed Traffic Load = 69 906 kg - 54 087 kg = 15 819 kg
