1. Gear-up.
2. Flaps-UP.
3.
Landing lights - OFF.
4.
Climb power - Set.
5.
PROP SYNC Switch - As required
06.
YAW DAMP switch - As required.
0
Autofeather switch - As required.
Brake deice - As required.
9
Windshield Anti-ice - As required.
NOTE
Turn windshield anti-ice on to normal when
passing 10,000 feet AGL or prior to entering the
freezing level (whichever comes first). Leave
on until no longer required during descent for
landing. High temperature may be selected as
required, after a minimum warm-up period of
15 minutes.
10. Cabin pressurization - Check, adjust RATE control
knob so that cabin rate-of-climb equals one-third
aircraft rate-of-climb.

11. Wings and nacelles - Check.
0
12. Flare/chaff dispenser safety pin (electronic
module) - Remove.
0
Chaff function selector switch - As required.
14. APR-39 and APR-44 - As required.
8-43. CLIMB.
a. Cruise Climb. Cruise climb is performed at a
speed which is the best combination of climb, fuel
bum-off, and distance covered Set propellers at
1900 RPM and torque as required. Adhere to the
following airspeed schedule as closely as possible.
SL to 10,000 feet
140 KIAS
10,000 to 20,000 feet
131 KIAS
20,000 to 31,000 feet
121 KIAS
b. Climb -
Maximum Rate. Maximum rate of
climb performance is obtained by setting propellers
at 2,000 RPM. torque at 100% (or maximum climb
TGT), and maintaining best rate-of-climb airspeed.
Refer to Chapter 7 for best rate-of-climb airspeed
for specific weights.
8-44. CRUISE.
Cruise power settings are entirely dependent upon
the prevailing circumstances and the type of mission
being flown. Refer to Chapter 7 for airspeed, power
settings, and fuel flow information. The following
procedures are applicable to all cruise requirements.
TM 55-1510-221-10
1. Power - Set. Refer to the cruise power graphs con-
tained in Chapter 7. To account for ram air
temperature increase, it is essential that tempera-
ture be obtained at stabilized cruise airspeed.
NOTE
A new engine operated at the torque value
presented in the cruise power charts will show a
TGT margin below the maximum cruise limit.
Maximum cruise power settings for temperature
and altitude (derived from Chapter 7) if
exceeded will adversely affect engine life. With
ice vanes retracted, if cruise torque settings
shown on cruise power charts cannot be ob-
tained without exceeding TGT limits, the en-
gine should be inspected.
2. Ice & rain switches - As required. Insure that anti-
ice equipment is activated before entering icing
conditions.
NOTE
Ice vanes must be extended when operating in
visible moisture at +5°C or less. Visible mois-
ture is moisture in any form (clouds, ice crys-
tals, snow, rain, sleet, hail, or any combination
of these).
0
3. Auxiliary fuel gages - Monitor. Insure that fuel is
being transferred from auxiliary tanks. (Chapter 2,
Section IV.)
0
4. Altimeters - Check. Verify that altimeter setting
complies with transition altitude requirement.
05. Engine instrument indications - Check all engine
instruments for normal indications.
6. Recognition lights - As required.
8-45. DESCENT.
Descent from cruising altitude should normally be
made by letting down at cruise airspeed with
reduced power. Refer to Chapter 7 for power set-
tings and rates of descent.
NOTE
Cabin altitude and rat-f-climb controller
should be adjusted prior to starting descent.
a. Descent - Max Rate (Clean). To obtain the
maximum rate of descent in clean configuration, per-
form the following:
0
1. Cabin pressurization - Set. Adjust CABIN CON-
TROLLER dial as required and adjust RATE con-
trol knob so that cabin rate of descent equals
one-third aircraft rate of descent.
