Given:

Dry Operating Mass = 38 000 kg
Maximum Structural Take-off Mass = 72 000 kg
Maximum Landing Mass = 65 000 kg
Maximum Zero Fuel Mass = 61 000 kg
Trip Fuel = 8000 kg
Take-off Fuel = 10 300 kg

The maximum allowed take-off mass and traffic load are respectively…

  • A
    71 300 kg and 25 300 kg
  • B
    73 000 kg and 27 000 kg
  • C
    71 300 kg and 23 000 kg
  • D
    73 000 kg and 24 700 kg

Refer to figure.
Put simply, traffic load (TL) it is the difference between the Operating Mass (dry operating mass plus fuel, but without any traffic load) and the actual take-off mass.

Calculate the Operating Mass:
DOM + take-off fuel = 38 000 + 10 300 = 48 300 kg

Determine the maximum permitted Take-off Mass, which is the lowest of the following:

  • MTOM = 72 000 kg
  • MZFM + take-off fuel = 61 000 + 10 300 = 71 300 kg (limiting take-off mass)
  • MLM + trip fuel = 65 000 + 8 000 = 73 000 kg

Compute the allowable Traffic Load:
TOM - Operating Mass = 71 300 - 48 300 = 23 000 kg
