Given:

Zero Fuel Mass: 4920 kg
Trip Fuel: 880 kg
Block Fuel: 1330 kg
Taxi Fuel: 25 kg

The actual Take-Off Mass is equal to:

  • A
    6810 kg
  • B
    6360 kg
  • C
    6225 kg
  • D
    6250 kg

The actual Take-off mass is the mass of the aircraft at the start of the take-off run and equal to the Zero Fuel Mass (ZFM) plus the Take-off fuel.

The Take-off fuel is the fuel mass of the aircraft at the start of the take-off run and equal to the Block (Ramp) fuel minus the Taxi fuel: 1 330 kg - 25 kg = 1 305 kg.

Thus, the actual Take-off mass is: ZFM + Take-off fuel = 4 920 kg + 1 305 kg = 6 225 kg.
