NORMAL PROCEDURES
TAKEOFF
POWER SETTING
Refer to the Takeoff Torque figure in Section 5 to determine the torque
corresponding to the surface altitude and OAT conditions. This torque
should be obtainable without exceeding 805°C
ITT or 101.6% Ng.
Takeoff roll is mosr smoorhly Initiated by gradually advancing the power
lever until propeller
RPM
nears 1900. Smoothly release tne brades and
continue advancing the power lever until the takeoff torque (from
Section 5) is reached.
NOTE
As
air~~eed increases durina takeoff. an increase in toraue
at a
fixed power lever positron
IS
normal and need not'be
reduced Drovided toraue limit (1865 foot-~ounds) is not
exceeded.
WING FLAP SETTINGS
A flap setting of 20" is recommended for all takeoffs unless a strong
crosswind exists at which time 10" flaps may be preferred. Use of 20"
flaps provides for a lower liftoff speed, as well as a reduction in ground
roll and total distance over an obstacle compared to takeoff with flaps
UP.
=,
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 83 KlAS
=,
with 20" flaps. Takeoff performance data is shown in Section 5 based
on this speed and configuration.

NOTE
2,
The 83 KlAS obstacle clearance speed is a recommended
safe speed under all conditions, including turbulence and
complete engine failure. The actual
V,
speed with flaps 20"
=,
is 70 KlAS at maximum takeoff weight as noted in the Flaps
20" Climb Gradient chart in Section 5.
