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): 1800 kg
Regulated Take-Off Mass (RTOM): 3000 kg
Maximum Landing Mass (MLM): 2200 kg
Fuel Tank Capacity: 550 kg
Trip Fuel (TF): 190 kg
Minimum Block Fuel (BF): 350 kg
Taxi Fuel: 15 kg

• A
255 kg.
• B
Not able to carry Extra Fuel.
• C
215 kg.
• D
200 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
Note: MZFM does not limit fuel.

(1) BASED ON RTOM:

• RTOM – (ATOM) = 3 000 kg – 2 135 kg = 865 kg
• ATOM = AZFM + Take Off fuel = 1 800 kg + 335 kg = 2 135 kg
Take-off fuel = Block fuel – taxi fuel

(2) BASED ON MLM:

• MLM – Landing mass = 2 200 kg – 1 945 kg = 255 kg
• LM = ATOM - Trip fuel = 2 135 kg - 190 kg = 1 945 kg

(3) BASED ON TANK CAPACITY:

550 kg - 350 kg = 200 kg

=> The most restricting value in based on tank capacity: 200 kg.
