A jet transport has the following structural limits:

Maximum Ramp Mass: 63 060 kg
Maximum Take-off Mass: 62 800 kg
Maximum Landing Mass: 54 900 kg
Maximum Zero Fuel Mass: 51 300 kg

The aeroplane fuel is loaded accordance with the following requirements:

Taxi Fuel: 400 kg
Trip Fuel: 8 400 kg
Contingency and Final Reserve Fuel: 1 800 kg
Alternate Fuel: 1 100 kg

If the Dry Operating Mass (DOM) is 34 930 kg, determine the maximum Traffic Load (TL) that can be carried on the flight if departure and landing airfields are not performance limited.

  • A
    17 070 kg
  • B
    16 570 kg
  • C
    16 370 kg
  • D
    16 430 kg

To determine the maximum traffic load.

We need to identify the actual Takeoff mass, the smallest of:
- Maximum takeoff mass = 62800
- Maximum Landing mass + trip fuel = 54900 + 8400 = 63300
- Maximum zero fuel mass + takeoff fuel = 51300 + + 8400 + 1100 + 1800 = 62600 kg

Maximum allowable takeoff mass = 62600 kg

Takeoff mass = DOM + Traffic Load + takeoff fuel
Traffic load = Takeoff mass — DOM — takeoff fuel

Traffic load = 62600 — 34930 — 8400 — 1100 — 1800 = 16370 kg

Correct Answer: 16370 kg
