where maximum power cannot be maintained. Refer
to Chapter 7 for rate of-climb airspeed for specific
1. YD switch As required.
2. Cabin pressurization Check. Adjust
RATE control knob so that cabin rate-of-
climb equals one-third aircraft rate-of-climb.
3. AUTOFEATHER switch As required.
4. BRAKE DEICE As required.
Turn the windshield heat on to
NORMAL when passing 10,000 feet
MSL or prior to entering the freezing
level, whichever comes first. Leave
on until no longer required during
temperature may be selected as
required after a minimum warmup
period of 15 minutes.
5. WSHLD ANTI-ICE As required.
6. Wings and nacelles Check.
7. TCAS Set range.
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
1. Power Set. Refer to the cruise power
graphs contained in Chapter 7. To account
for ram air temperature increase, it is
essential that temperature be obtained at
stabilized cruise airspeed. Power is set
using RPM and torque as the primary
control. Maximum allowable torque must
not be exceeded and TGT must also be
observed as a separate limit.
A new engine operated at the torque value
presented in the cruise power charts will
show a TGT margin below the maximum
cruise limit for the torque value presented
in the charts. With ice vanes retracted, if
cruise torque settings shown on the cruise
power charts cannot be obtained without
exceeding TGT limits, the engine should be
2. ICE & RAIN switches As required.
Ensure that anti-ice equipment is activated
before entering icing conditions.
Ice vanes must be extended when
operating in visible moisture at +5 °C or
less. Visible moisture is any form of
clouds, ice crystals, snow, rain, sleet, hail,
or any combination of these.
3. CABIN SIGNS switch As required.
4. AUXILIARY fuel gauges Monitor. Ensure
that fuel is being transferred from auxiliary
tanks. (Chapter 2, Section IV.)
5. Altimeters Check. Verify that altimeter
setting complies with transition altitude
6. Engine instrument indications Noted.
Check all engine instruments for normal
7. RECOG lights As required.
8. TCAS Set for en route.
Descent from cruising altitude should normally
be made by letting down at cruise airspeed with
reduced power. Refer to Chapter 7 for power settings
and rates of descent.
Cabin pressure controller should be
adjusted prior to starting descent.
a. DESCENT Max Rate (Clean). To obtain
the maximum rate of descent in clean configuration,
perform the following.
1. Cabin pressurization Set. Adjust CABIN
CONTROLLER dial as required and adjust
RATE control knob so that cabin rate of
descent equals one-third aircraft rate of
