Given the following information for an aircraft, what is its maximum Traffic Load available?

Dry Operating Mass: 3 000 kg.
Maximum Take-off, Landing, and Zero-fuel Mass: 5 200 kg.
Ramp Fuel: 650 kg
Taxi Fuel: 50 kg.

  • A
    2 200 kg.
  • B
    1 550 kg.
  • C
    1 600 kg.
  • D
    2 150 kg.

Since all structural limits are identical and all of them contain at least the DOM, the most limiting factor is the MTOM, because, in addition to the DOM, it contains also the greatest amount of fuel, the Take-off fuel (in comparison with the landing fuel), which if subtracted will give the maximum available Traffic Load.

Thus, the Maximum available TL will be: MTOM - DOM - Take-off fuel = MTOM - DOM - (Ramp fuel - Taxi fuel) = 5 200 kg - 3 000 kg - (650 kg - 50 kg) = 1 600 kg.

Alternatively, using a tabular format, find the maximum TL in terms of each structural limit and keep the lowest one:

MTOM: 5 200 kg MZFM: 5 200 kg MLM: 5 200 kg
- DOM 3 000 kg 3 000 kg 3 000 kg
- FUEL T/O fuel:
650 - 50 = 600 kg
- Landing fuel:
less than 600 kg
= TL 1 600 kg 2 200 kg More than 1 600 kg

Thus, the lowest TL, 1 600 kg, in terms of MTOM, is the Maximum available TL.
