TAKEOFF
(See charts in Section
5)
The normal takeoff technique
is
conventional. The tab should
be
set
slightly aft
of
neutral, with the exact setting determined by the loading of the
airplane. Allow the airplane
to
accelerate to
45
to
55
KlAS depending on
the weight of the aircraft and ease back on the control wheel to rotate to
climb attitude. Premature raising
of
the nose or raising
it
to an excessive
angle· will result in a delayed takeoff. After takeoff, let the airplane accelerate
to
the desired climb speed
by
lowering the nose slightly.
Takeoffs are normally made with flaps up; however, for short field
takeoffs and for takeoffs under difficult conditions, such
as
deep grass or a
soft surface, total distances can
be
reduced appreciably by lowering the
flaps to
25°
and rotating
at
lower airspeed.
A short field takeoff
is
accomplished without flaps by applying full
power before brake release; lift off at
40-52
KIAS (depending on weight) and
accelerate to and maintain
44-57
KIAS (depending on weight) past obstacle
and
climb out at
79
KIAS.
A short field takeoff with an obstacle clearance
is
accomplished
by
first
lowering the flaps to
25°. Apply full power before brake release and accel-
erate
to
40-52 KIAS (depending on weight) and rotate. Accelerate
to
and
maintain
44-57 KIAS (depending on weight) until obstacle clearance
is
attained. After the obstacle has been cleared, accelerate to
79
KIAS and then
slowly retract the flaps.
Takeoff from a soft field with an obstacle clearance requires the use of
25°
flaps. Accelerate the airplane and lift the nose gear off as soon
as
possible
and lift off at the lowest possible airspeed. Accelerate just above the ground
to
52
KIAS to climb past obstacle clearance height. Continue climbing while
accelerating to the best rate
of
climb speed,
79
KIAS and slowly retract the
flaps.
For
a soft field takeoff without an obstacle to clear, extend the flaps 25°,
accelerate the airplane and lift the nose gear off as soon
as
possible. Lift off
at
the lowest possible airspeed. Accelerate just above the ground to the best
rate
of
climb speed,
79
KIAS, and retract the flaps while climbing out.
