Refer to figure or CAP758 Figure 3.14.
Given the following information, determine the All Engines Operating cruise fuel consumption for the TETH:

Cruise altitude: FL050
OAT: ISA
Mass: 8000 kg
Ground Distance: 95 NM
TAS: 130 kt
Wind: 15 kt headwind

  • A

    329 kg

  • B

    353 kg

  • C

    373 kg

  • D

    410 kg

Refer to figure.
1. Two-engine hourly fuel consumption:

  • Enter with the density altitude 5000 ft and move horizontally to the right until crossing the 8000 kg mass line.
  • Continue vertically down and read the hourly fuel consumption: 450 kg/hr.

2. Flight time:

  • Groundspeed = TAS - Headwind component = 130 kt - 15 kt = 115 kt.
  • Flight time = Ground distance / Groundspeed = 95 NM / 115 kt = 0.83 hr.

3. AEO cruise fuel consumption: Hourly fuel consumption x Flight time = 450 kg/hr x 0.82 hr = 373 kg.
