Refer to figure.
Given:

Planned and actual data as shown in the Flight Log excerpt. Provided that flight conditions on the leg GAMMA to DELTA remain unchanged and fuel consumption remains unchanged, what fuel remaining should be expected at waypoint DELTA?

  • A

    4690 kg

  • B

    5090 kg

  • C

    4940 kg

  • D

    5010 kg

First Step: Calculate the actual fuel consumption BETA - GAMMA

  • Fuel consumed BETA - GAMMA = Actual Fuel remaining at BETA - Actual Fuel Remaining at GAMMA
  • 5440 kg – 5340 kg = 100 kg
  • Time BETA – GAMMA = 1:53 – 1:43 = 10 min
  • Fuel Consumption = 100 / 10 = 10 kg/min

Second Step: Calculate fuel consumed GAMMA - DELTA
Note: provided that the flight conditions will not change, the ATA over DELTA will be equal to ETA => 2:33.
TIME GAMMA - DELTA = 2:33 - 1:53 = 40 min
Fuel consumed: 40 min x 10 kg/min = 400 kg

Third Step: Calculate Fuel remaining at DELTA
FUEL at DELTA = Actual Fuel over GAMMA - Fuel Consumed (GAMMA - DELTA)
FUEL at DELTA = 5340 kg – 400 kg = 4940 kg
