The resultant cruise distance is:
Total Distance............................................................ 460.0 NM
Climbout Distance...................................................... - 12.0 NM
Cruise Distance.......................................................... 448.0 NM
With an expected 10 Kt headwind, the ground speed for cruise
is predicted to be:
101 Knot
- 10 Knot
91 Knot
Therefore, the time required for the cruise portion of the trip is:
The fuel required for cruise is:
4.9 h x 18.6 l/h = 91.1 l (24.0 US gal)
The total estimated fuel required is as follows:
Engine Start, Taxi and Takeoff ..................... 4.0 l (1.1 US gal)
Climb................................................... + 5.3 l (1.4 US gal)
Cruise.................................................. + 91.1 l (24.0 US gal)
Total fuel required............................... 100.4 l (26.5US gal)
This gives with full tanks a reserve of:
168.8 l (44.6 US gal)
- 100.4 l (26,5 US gal)
68.4 l (18.1 US gal)
Once the flight is underway, ground speed checks will provide a
more accurate basis for estimating the time enroute and the
corresponding fuel required.
