Wind Component Chart (Figure 5-9) ~
(1) The angle between the runway and the prevailing wind is 40
0
.
(2) Enter Figure 5-9 on the 40° wind line and proceed out to the
intersection with the 25-knot arc.
(3)
Read horizontally left from this intersection; the headwind
component is 19 knots.
Normal Takeoff Distance (Figure 5-10)
(1) Enter Figure 5-10 at 6500 pounds weight; the takeoff and climb
speed
is 92 K1AS.
(2) Proceed horizontally right from 3000 foot pressure altitude to
the
vertical columns for 200C (68°F). The takeoff ground roll
is 2000 feet and the total distance required to clear a 50-foot
obstacle
is 2450 feet without wind correction. With a 19-knot
headwind component, the corrected takeoff ground run is 1772
feet and the corrected total distance required is 2171 feet.
