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

Maximum Zero Fuel Mass (MZFM): 2000 kg
Actual Zero Fuel Mass (AZFM): 2000 kg
Regulated Take-Off Mass (RTOM): 2900 kg
Maximum Landing Mass (MLM): 2600 kg
Fuel Tank Capacity: 950 kg
Trip Fuel (TF): 350 kg
Minimum Block Fuel (BF): 500 kg

  • A
    450 kg.
  • B
    400 kg.
  • C
    600 kg.
  • D
    Not able to carry Extra Fuel.
In order to find out the amount of fuel which can be uplifted you have to calculate the MTOM, MLM and tank capacity limitation
Note: MZFM does not limit fuel.
BASED ON RTOM:
  • RTOM – (ATOM) = 2900 kg - 2500 kg = 400 kg
  • ATOM = AZFM + Take Off fuel = 2000 kg + 500 kg = 2500 kg
Since we are not provided with taxi fuel => we will assume our take off fuel equals our block fuel.
BASED ON MLM:
  • MLM – Landing mass = 2600 kg - 2150 kg = 450kg
  • LM = ATOM - Trip fuel = 2500 kg - 350 kg = 2150 kg
BASED ON TANK CAPACITY:
950 kg - 500 kg = 450 kg
=> The most restricting value in based on RTOM 400 kg.
