You are to determine the maximum fuel load which can be carried in the following conditions:

Dry Operating Mass : 2800 kg 
Trip Fuel : 300 kg 
Traffic Load : 400 kg 
Maximum Take-off Mass : 4200 kg 
Maximum Landing Mass : 3700 kg

  • A
    800 kg
  • B
    1000 kg
  • C
    700 kg
  • D
    500 kg

1. First check the Maximum Take Off Mass.
Select the lowest of Maximum Take-Off Mass (MTOM) and Maximum Landing Mass + Trip Fuel

  • MTOM = 4200 kg
  • Maximum Landing Mass + Trip Fuel = 3700 kg + 300 kg = 4000 kg (lowest)

We want to find the amount of extra fuel we can carry on top of the minimum take-off fuel:

2. Add up the Dry Operating Mass (DOM), Traffic Load and all the fuel.

2800 kg (DOM) + 400 kg (Load) + 300 kg (min TOF) = 3500 kg

3. Subtract 3500 kg from the MTOM calculated in Step 1 to get the underload

4000 kg – 3500 kg = 500 kg of Extra Fuel that can be carried

The maximum allowable take-off fuel equals the trip fuel plus the extra fuel which can be carried

  • 300 kg + 500 kg = 800 kg
