The takeoff distance chart. figure 5-4. should
b~
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 2950 pounds. pressure altitude of 2000 feet and a temperature of
30°C should be used and results in the following:
Ground roll
Total distance to clear a
50~foot
obstacle
930 Feet
1800 Feet
These distances are well within the available takeoff field length. Howev-
er. 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
