Climb
To achieve an appropriate climb conguration, reduce propeller RPM to 1900
or 2000 RPM, as desired (check the performance charts for appropriate RPM
settings). When passing the transition altitude, set your altimeter to standard
pressure (29.92 inches or 1013 hpa). Altitudes above the transition altitude are
referred to as “ight levels”. As the landing gear is already retracted, turn OFF
the landing lights. No-smoking and seatbelt signs may be set as desired.
When reaching higher ight levels during climb, the maximum available torque
will start to decrease. Consult the performance chart “Maximum climb power –
torque” and the kneeboard reference section for maximum climb power settings
and recommended climb speeds. Closely monitor ITT, and start to lower the nose
to avoid a drop in speed. On the Cheyenne II and IIXL, you may want to use
autopilot modes IAS or SPD PRF to adjust your pitch attitude automatically.
When reaching the armed altitude, the plane gently acquires a lower climb rate
and will subsequently level off at the desired ight level. The autopilot switches
from ALT ARM to ALT HOLD. If you want to stay at that level, you need to adjust
the engines to the recommended cruise power settings. If this was just an interim
level-off and you intend to continue the climb, (you may have been cleared
by ATC to that interim level only), dial in the new altitude with the altitude
preselector, select ARM, and establish again a climb pitch attitude. Typical climb
rates at higher ight levels are around 1000 fpm (feet per minute).
Cruise
When cruise level is reached, apply recommended cruise power settings, as
indicated on the performance tables. For example, a typical cruise in the Cheyenne I
at FL240 means 833 ft-lb torque at 2000 RPM, which will result in around 230 kts
TAS cruising speed. Some Cheyenne models also differentiate between Maximum
Cruise Power (basically the maximum speed you can achieve) and Economy Cruise
Power, which offers the best trade between ight time and range.
