CESSNA AIRCRAFT COMPANY FOR TRAINING USE ONLY
MODEL 152 5-6
With an expected 10 knot headwind, the ground speed for cruise is predicted to be:
99
-10
89 Knots
Therefore, the time required for the cruise portion of the trip is:
310
89
= 3.5 ℎ
The fuel required for cruise is:
3.5 Hours × 5.2 gallons/hour = 18.2 Gallons
The total estimated fuel required is as follows:
Engine start, taxi, and takeoff 0.8
Climb 1.2
Cruise 18.2
Total fuel required 20.2 Gallons
This will leave a fuel reserve of:
24.5
-20.2
4.3 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 distances for various airport altitude and temperature
combinations using the short field technique. The distances corresponding to 2000 feet and 30°C are as
follows:
Ground roll 535 Feet
Total distance to clear a 50-foot obstacle 1300 Feet
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.
