Similarly, the distance for descent may be corrected for the effect of
wind and results in 40 nautical miles.
The cruise distance is then determined by subtracting the distance
during climb and distance during descent.
Total distance: 650
Distance during climb and descent
- -70
Cruise distance 580 Nautical Miles
With an expected 10 knot headwind, the ground speed for cruise is
predicted to be:
158
148 Knots
Therefore, the time required for the cruise portion of the trip is:
Nautical Miles
148 Knots
= 3.9 Hours
The fuel required for cruise is:
3.9 hours
X 306 poundslhour = 11 94 Pounds
A 45-minute reserve requires:
45
-
60 X 306 poundslhour = 230 Pounds
