Given the following information for a Commercial Air Transport operation, calculate the maximum possible Extra Fuel to be uplifted.

Maximum Zero Fuel Mass: 62731 kg
Actual Zero Fuel Mass: 62700 kg
Regulated Take-Off Mass: 76000 kg
Maximum Landing Mass: 66360 kg
Fuel Tank Capacity: 16000 kg
Taxi Fuel: 240 kg
Trip Fuel: 10000 kg
Minimum Block Fuel: 13100 kg

  • A
    440 kg.
  • B
    Not able to carry Extra Fuel.
  • C
    2900 kg.
  • D
    2460 kg.
In order to find out the amount of fuel which can be uplifted you have to calculate the MTOM, MLM and tank capacity limitation - the most limiting value obtained from these calculations will be the maximum fuel which can be uplifted.
Note: MZFM does not limit fuel.
BASED ON REGULATED TAKE OFF MASS (RTOM):
  • RTOM – (ATOM) = 76 000 kg - 75 560 kg = 440 kg
  • ATOM = AZFM + Take Off fuel = 62 700 kg + (13 100 kg - 240 kg) = 75 560 kg
* Take Off fuel = Minimum Block Fuel - Taxi Fuel
BASED ON MAXIMUM LANDING MASS (MLM):
  • MLM – Landing mass = 66 360 kg - 65 560 kg = 800 kg
  • LM = ATOM - Trip fuel = 75 560 kg - 10 000 kg = 65 560 kg

BASED ON TANK CAPACITY:
16 000 kg - 13 100 kg = 2 900 kg
=> The most restricting value in based on REGULATED TAKE OFF MASS (RTOM): 440 kg.
