CESSNA SECTION 5
MODEL 152 PERFORMANCE
1 July 1978 5-4
CRUISE CONDITIONS
Total distance 320 Nautical Miles
Pressure altitude 5500 Feet
Temperature 20°C (16°'C above standard)
Expected wind enroute 10 Knot Headwind
LANDING CONDITIONS
Field pressure altitude 2000 Feet
Temperature 250C
Field length 3000 Feet
TAKEOFF
The takeoff distance chart, figure 5-4, should be consulted, keeping in mind that the distances
shown are based on the short field technique. Conservative distances can be established by
reading the chart at the next higher value of altitude and temperature. For example, in this
particular sample problem, the takeoff distance information presented for a pressure altitude of
2000 feet and a temperature of 30'C should be used and results in the following:
Ground roll 80 Feet
Total distance to clear a 50-foot obstacle 20 Feet
These distances are well within the available takeoff field length. However, a correction for the
effect of wind may be made based on Note 3 of the takeoff chart. The correction for a 12 knot
headwind is:
(12
Knots/9 Knots) X .10% = 13% Decrease
This results in the following distances, corrected for wind:
Ground roll, zero wind 980
Decrease in ground roll (980 feet x 13%) 127
Corrected ground roll 853 Feet
Total distance to clear a 50-foot obstacle, zero wind 1820
Decrease in total distance (1820 feet x 13%) 237
Corrected total distance to clear 50-foot obstacle 1583 Feet
