AFTER TAKEOFF
Ice Protection Test (if applicable) ..........COMPLETE
Ice Detection Override Knob..................AUTO
Monitor weather conditions for an encounter with ice for the
remainder of the flight. Closely monitor the static air temperature
indication so that when moisture is present, a look at the windshield
and, if installed, the windshield wiper will indicate if ice is
accumulating. Notwithstanding installation of the ice detector, the
crew remains responsible for monitoring icing conditions and for
manual activation of the ice protection system whenever
necessary.
Ignition....................................................AS REQUIRED
CLIMB/CRUISE
If engine vibration increases, advance thrust levers, one at a time, to
obtain 60% N1
minimum for 5 seconds, and then return to the former
s
etting.
If ITT increases beyond limits, reduce Thrust Levers as required to
maintain ITT within limits.
When flying in icing conditions or after flying in icing conditions, ice
accretion on unprotected areas may cause vibration at high speeds. If
vibration and/or buffeting occurs, a change in the current airspeed will
eliminate these effects. At high speeds reduce the airspeed as
required, limited to a minimum of 200 KIAS. Observe normal (including
operation in icing conditions) procedures contained in the approved
AFM.
No special technique is required to fly with the autopilot on or off.
Climb using FLC mode provides enough speed margin to stall. SPD
and VS modes may also be used, provided that the airspeed is not
allowed to decrease below 200 KIAS (when flying IAS) or 0.56 M
(when flying Mach). During autopilot operation, monitor pitch attitude
and speed continuously.
If BLD 1 (2) LOW TEMP message appears, advance Thrust Lever until
the message disappears and check bleed temperature pointer (MFD
ECS and Pneumatic page) in the green range.
During cruise, observe minimum fuel tank temperature (-40°C). If fuel
temperature is reaching the limit, apply the FUEL LOW
TEMPERATURE procedure in the AFM.
