The total estimated fuel required is as follows:
SECTION 5
PERFORMANCE
Engine start, taxi, and takeoff
1.1
Climb
1.5
Cruise
30.5
Total fuel required
33.1 GaIIons
This will leave a fuel reserve of:
40.0
-3 3. 1
6.9 Gallons
Once the flight is underway, ground speed checks will provide a
more accurate basis for estimating the time enroute and the corres-
ponding fuel required to complete the trip with ample reserve.
L A N D ING
A procedure similar to takeoff should be used for estimating the
landing distance at the destination airport. Figure 5-10 presents land-
ing distance information for the short field technique. The distances
corresponding to 2000 feet and 30oC are as follows:
Ground roll 590 Feet
Total distance to clear a 5O-foot obstacle 1370 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.
