Actual Ground Speed (GS) on the leg waypoint 5 - 6 is 420 kt. Based on the planned and actual data shown in the flight log excerpt and provided that fuel consumption remains unchanged from previous leg, what remaining fuel should be expected at waypoint 6?
Distance: 118 NM
GS: 471 kt
Fuel consumed = Fuel at WYPT 4 - Fuel at WYPT 5 Fuel consumed = 7.8 t - 7.2 t = 0.6 t |
Flight time = (118 NM / 471 kt) x 60 min / h = 15 min Fuel Flow (FF) = (0.6 t / 15 min) x 60 min / h = 2.4 t/h |
Flight time: 35 min
Distance WYPT 5 - WYPT 6: 33 NM GS: 420 kt Flight Time = (33 NM / 420 kt) x 60 min / h = 4.71 min |
(2.4 t / h x 4.71 min) : 60 min / h = 0.188 t |
3) Determine fuel remaining at WYPT 6:
Fuel at WYPT 5- Fuel consumed between WYPT 5 and WYPT 6 7.2 t - 0.188 t = 7.012 t = 7 012 kg |
