(For this question use annex 033-043 and 033-055 rev. 05.11.2004).
The flight crew of a turbojet aeroplane prepares a flight using the following data:

Flight leg air distance: 2 700 NM
Flight level FL 310, true airspeed: 470 kt
Tailwind component at this level: 35 kt
Initially planned take-off mass (without extra fuel on board): 180 000 kg
Fuel price: 0.28 Euro/l at departure 0.26 Euro/l at destination

To maximize savings, the commander chooses to carry extra fuel in addition to that which is necessary. The optimum quantity of fuel which should be carried in addition to the prescribed quantity is:

  • A
    10 000 kg
  • B
    6 000 kg
  • C
    The fuel transport operation is not recommended in this case.
  • D
    4 000 kg
Fuel tankering is a practice whereby an aircraft carries more fuel than required for its next flight (trip fuel + reserve) in order to reduce or avoid refuelling at the destination airport.
  • Tankering will be considered if the cost of fuel at destination is higher than at the departure aerodrome.
In this case, no calculations are needed. At departure aerodrome: Fuel price: 0.28 Euro/l and at destination: 0.26 Euro/l => Fuel is cheaper at the destination, therefore, tankering makes no sense.
