NORMAL PROCEDURES
easier nose wheel lift-off and lower initial climb attitude, as well as a 10%
reduction in ground run and total distance over an obstacle compared to
takeoff with flaps up. Compared to 20° flaps, use of 10° flaps facilitates
transition to normal climb without significantly increasing total takeoff
distance over an obstacle.
The use of 20° flaps is reserved for minimum ground runs or takeoffs
from soft or rough fields, since it will allow safe use of slower takeoff
speeds, resulting in shortening the ground run approximately 10% com-
pared to 10° flaps. However, most of the advantage is lost
in
the climb to the
obstacle.
Flap settings greater than 20° are not approved for takeoff.
SHORT FIELD TAKEOFF
_.., If
an obstruction dictates the use of a steep climb angle, after liftoff
accelerate to and climb out at an obstacle clearance speed of 75 KIAS with
10° flaps and gear extended. This speed provides the best overall climb
speed to clear obstacles when taking into account the turbulence often
found near ground level. The takeoff performance data in Section 5 is based
on this speed and configuration.
Minimum ground run takeoffs are accomplished using
20°
flaps
by
lifting the nose wheel off the ground as soon as practical and leaving the
ground in a slightly tail-low attitude. However, the airplane should be
leveled off immediately to accelerate to a safe climb speed. If 20° of flaps
are used on soft or rough fields with obstacles ahead, it is normally
preferable to leave them extended rather than partially retract them in the
climb to the obstacle. With 20° flaps, use an obstacle clearance speed of 70
KIAS. After clearing the obstacle, and reaching a safe altitude, the flaps
may be retracted slowly as the airplane accelerates to the normal climb-
out speed.
CROSSWIND TAKEOFF
Takeoffs into strong crosswinds normally are performed with the
minimum flap setting necessary for the field length, to minimize the drift
angle immediately after takeoff. With the ailerons deflected partially into
the wind, the airplane is accelerated to a speed higher than normal, and
then pulled off abruptly to prevent possible settling back to the runway
while drifting. When clear of the ground, make a coordinated turn into the
f ' ' ~ .
wind to correct for drift.
LANDING GEAR RETRACTION
Landing gear retraction normally is started after reaching the point
