Refer to Jeppesen GSPRM Training Route Manual - Chart "E LO 1"
An aircraft is flying along airway Y904 from NANEV (N57º34'29", W002º27'14") to WICK VOR/DME (WIK, N58º27'32", W003º06'01"). Given the following data, the remaining fuel when arriving at WICK VOR/DME is:

Fuel over NANEV: 650 kg
TAS: 200 kt
Wind component: +17 kt
Fuel flow: 180 kg/h

  • A
    585 kg
  • B
    594 kg
  • C
    603 kg
  • D
    614 kg

Refer to figure.

(1) Calculate the flight time from NANEV to WICK VOR/DME:
The distance from NANEV to WICK can be obtained from the chart: 44 NM + 13 NM = 57 NM

Ground Speed (GS) = TAS + Tailwind Component = 200 kt + 17 kt = 217 kt

Flight time NANEV – WICK = Distance / GS
Flight time NANEV – WICK = (57 NM / 217 kt) x 60 = 15.76 min

(2) Calculate the fuel consumed from NANEV to WICK VOR/DME:
Fuel Flow: 180 kg/h
Fuel consumed = (15.76 min x 180 kg/h) / 60 = 47 kg

(3) Calculate the fuel remaining at WICK:
Fuel over NANEV equals 650 kg.
The fuel consumed between NANEV and WICK is 47 kg.
  • Therefore, over WICK the estimated fuel is = 650 kg – 47 kg = 603 kg
