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 weight, altitude and temperature. For example, in this
particular sample problem, the takeoff distance information presented for
a weight of 3100pounds, pressure altitude of 4000feet and a temperature of
30°C should be used and results in the following:
Ground roll
Total distance to clear a 50-foot obstacle
1215Feet
2310 Feet
These distances are well within the available takeoff field length. How-
ever, a correction for the effect of wind may be made based on Note 2 of the
takeoff chart. The correction for a 12 knot headwind is:
