Cessna 172 P - Landing Performance

Using a similar procedure for
the distance to climb results in
12 nautical miles. The resultant
cruise distance is:
With an expected 10 knot
headwind, the ground speed for
cruise is predicted to be:
Therefor, the time required for
the cruise portion of the trip is:
The fuel required for cruise is:
A 45-minute reserve requires:
The total estimated fuel required is as follows:
3.0 hours 7.4 gallons/hour = 22.2 gallons

Once the flight is underway,
ground speed checks will
provide a more accurate basis
for estimating the time enroute
and the corresponding fuel
required to complete the trip
with ample reserve.
LANDING
A procedure similar to takeoff
should be used for estimating the
landing distance at the
destination airport. Figure 5-10
presents landing distance
information for the short field
technique. The distance
corresponding to 2000 feet and
30°C are as follows:
A correction for the effect of
wind may be made based on
Note 2 of the landing chart
using the same procedure as
outlined for takeoff.
