CESSNA SECTION 4

2088 (675 SHP)
NORMAL PROCEDURES
ENROUTE
CLIMB
Normally, maximum climb power is maintained during the climb to
cruise altitude. Adjust the power lever as required to prevent exceeding
maximum climb torque, maximum climb ITT of
765% or maximum
climb
Ng of 101.6%, whichever occurs first.
NOTE
Engine operations which exceed 740'C ITT may reduce
engine life.
At lower altitudes and cool outside air temperatures (below
approximately 7,500 feet), the engine will reach the torque limit before
reaching the
ITT or Ng limit. As the climb progresses and the torque is
maintained by power lever advancement, the ITT and
Ng will increase
until an altitude is reached where ITT or
Ngwill dictate power lever
positioning. When operating near the ITT
lim~t, advance power lever
slowly to allow the current ITT to be indicated. The rate of power (and
temperature) increase of the engine is greater than the response rate of
the ITT indicating system; therefore, a rapid power lever advance could
allow an over-temperature condition to exist momentarily in the engine
before the over-temperature would be indicated.
For maximum performance climb, the best rate-of-climb speed should
be used with 1900 RPM and maximum climb power. This speed is 104
KlAS from sea level to 10,000 feet, decreasing to 87 KlAS at 20,000
feet.
For improved visibility over the nose, a cruise climb speed of 115- 125
KlAS may be desirable at altitudes up to approximately 12,000 feet.
Also, for improved passenger comfort, propeller RPM may be reduced
to 1600, if desired. Adjust the power lever (in accordance with the
following table) to prevent exceeding maximum torque for the
corresponding RPM, maximum climb ITT of
765"C, or maximum Ng of
101.6%, whichever occurs first.
