TAKE O F F
The takeoff distance chart, figure
5-4 should be consultet, keeping
in mind that that the distances
shown are based on the short
field technique. Conservative
Ground roll
Total distance to clear a 50-foot obstacle
A correction for the effect of wind
may be based on Note 3 of the
12 Knots
9 Knots
This results in the following distances, corrected for wind:
Ground roll, zero wind
Decrease in ground roll
(1200 Feet
Corrected Ground Roll
Total distance to clear a
50-foot obstacle, zero wind
Decrease in total distance
(2220 Feet
Corrected total distance
to clear 50-foot obstacle

distances can be established by
reading the chart at the next
higher value of weight, altitude
and temperature. For example, a
weight of 2400 pounds, pressure

a 12 knot headwind is:
