Procedures
Crosswind Takeoff
Takeoffs into strong crosswinds may be performed with 10° or 20° of aps.
The ailerons should be deected fully into the wind when takeoff power is
rst applied. As the airplane is accelerated, the aileron deection should
be adjusted (decreased) appropriately. The airplane should be rotated at a
speed slightly higher than normal and pulled off abruptly to prevent it from
settling back to the runway while it is drifting. When the airplane is clear
of the ground, a coordinated turn should be made into the wind for drift
correction. Using 10° of aps will improve directional control and stability
in performing crosswind takeoffs, although the takeoff distance and rotation
speed will be increased.
CLIMB
Enroute Climb
Under normal conditions, maximum climb power may be maintained
throughout the climb, to the cruising altitude. Adjust the power lever as
required to remain within the maximum climb engine operating limits for
maximum climb ITT, maximum climb torque and maximum climb
%
(identied in “Section 2” of this manual) and the required placards.
At density altitudes lower than approximately 7500 feet, the engine will reach
the torque limit prior to reaching the ITT or
limit. Refer to the Max Torque
for Climb charts in “Section 5” of this manual. As the airplane continues to
climb and the power lever is adjusted to maintain the desired torque, the ITT
and N
will increase until one or the other will be established as the limiting
engine parameter. While the climb ITT limit is 765°C, it is recommended that
740°C be used as the ITT limit in normal operations. Doing so increases the
life of the engine. Once reaching either the ITT or
limits, the power lever
should be adjusted accordingly, to not exceed these limits. When operating
the engine near its ITT limit, use caution when advancing the power lever, as
the ITT indication system has some lag time. Even when monitoring the ITT
indicator, the limits could be exceeded if the power lever is advanced rapidly.
Climb performance is tabulated in “Section 5” of this manual, with a climb
speed of 1.3 V
1
(101 KIAS). If circumstances dictate some improvement
in climb rate, particularly at high altitude, the use of V
varies almost linearly from 100 KIAS at sea level to 80 KIAS at 25,000 feet.
A cruise climb speed of 110-120 KIAS may be used for improved visibility
over the engine cowling at altitudes up to approximately 15,000 feet. For
improved passenger comfort, the propeller RPM may be reduced to as low as
1900 RPM. Prior to decreasing propeller RPM, the power lever should rst
be adjusted to prevent an over-torque condition. When an increase in power
is desired, the propeller RPM should be increased rst and then followed by
an increase of torque with the power lever. All engine limitations must be
continuously monitored to prevent conditions which exceed those limits.
NOTE: To achieve the maximum horsepower ratings, use a minimum of
2000 RPM.
