TM 55-1510-222-10
8-27. CLIMB.
Cruise climb is performed at a speed which provides a
good rate-of-climb and sufficient visibility over the nose.
Propellers should be kept at 1700 RPM. Lower propeller
RPMs will reduce the amount of cabin noise, but will
degrade the aircraft climb performance. The following
chart may be used as an airspeed schedule.
SL
to
10,000 FEET 160 KIAS
10,000
to
20,000 FEET 140 KIAS
20,000
to
25,000 FEET 130 KIAS
25,000
to
35,000 FEET 120 KIAS
NOTE
The
maximum
rate
of
climb
performance is obtained by setting
maximum continuous power and
maintaining two-engine climb speed
(Refer to Chapter 7).
8-28. CRUISE.
Refer to Chapter 7 for airspeed, power settings, and fuel
flow information. The following procedures are to be
used for Cruise configuration:
1.
PowerSet.
2.
Ice and rain switches As required.
3.
Auxiliary fuel gages Monitor.
4.
Altimeters Check.
5.
Engine instrument indications Noted.
6.
Recognition lights As required.
8-29. DESCENT.
a.
Descent from cruising altitude should normally
be made by letting down at cruise airspeed with
reduced power. (Refer to Chapter 7 for performance
data).
NOTE
Cabin
altitude
and
rate-of-climb
controller should be adjusted prior
to starting descent.
b.
If required to descent at a low airspeed (e.g., to
conserve airspace min. turbulence), approach flaps and
landing gear may be extended to increase the rate and
angle of descent while maintaining the slower airspeed.
8-30. DESCENT-ARRIVAL.
Refer to Chapter 7 for performance data. Perform the
following checks prior to the final descent for landing:
WARNING
Mmo may be easily exceeded when
descending from high altitude. The
pilot should frequently cross check
the
airspeed
and
Mach
limit
indicators to avoid exceeding Mmo.
Exceeding Mmo could result in
structural failure and loss of airframe
integrity.
1.
Cabin controller- -Set.
2.
Ice & rain switches - -As required.
3.
Windshield anti-ice - -As required.
NOTE
Set windshield anti-ice to normal or
high as required well before descent
into icing conditions or into warm
moist air to aid in defogging. Turn
off windshield anti-ice when descent
is completed to lower altitudes and
when heating is no longer required.
This will preclude possible wind
screen distortions.
4.
Recognition lights ON.
5.
Radio altimeter As required.
6.
Altimeters Set to current altimeter setting.
7.
Flare/chaff dispenser arm-safe switch SAFE.
8.
Flare/chaff dispenser safety pin (electronic
module) Insert.
9.
Condition lever HIGH IDLE.
10.
Arrival briefing Complete.
8-31. BEFORE LANDING.
1.
Propeller synchronizer switch OFF.
2.
Autofeather switch ARM.
3.
Propeller levers HIGH RPM.
4.
Flaps (below 197 KIAS) APPROACH.
5.
Gear (below 178 KIAS) DN.
6.
Landing lights As required.
7.
Brake deice As required.
8-32. LANDING.
CAUTION
The maximum demonstrated cross
wind component is 25 knots at 90°.
Landing the aircraft in a crab will
impose side loads on the landing
gear and should be recorded on DA
Form 2408-13.
