An extract from a typical flight plan produced by an airline flight planning tool. The remaining fuel overhead KOGAS is 5210 kg. Assume that the fuel flow remains the same as experienced between OKEPI and KOGAS and that the actual times between the waypoints are as planned. What is the estimated remaining fuel overhead TOD?

  • A

    3222 kg

  • B

    3112 kg

  • C

    3326 kg

  • D

    3060 kg

For this question, the remaining fuel overhead KOGAS is 5210 kg, the fuel flow can be found using the data from OKEPI to KOGAS:

  • The planned flight time from OKEPI to KOGAS is: 01 + 02 + 02 + 06 + 04 + 05 = 20 min and it burns: 5990 kg - 5210 kg = 780 kg.
  • Thus, the aircraft's fuel flow → burns 780 kg for 20 min, burns X for 1 min → X = 39 kg/min

The flight time from KOGAS to TOD is: 07 + 02 + 23 + 17 + 3 = 52 min. So, the fuel required from KOGAS to TOD will be: 52 min x 39 kg/min = 2028 kg.

Therefore, the remaining fuel overhead TOD will be: Remaining fuel overhead KOGAS - Fuel required from KOGAS to TOD = 5210 kg - 2028 kg = 3182 kg.

The closest answer is 3222 kg.
