ENGINE START
SPS/ICE SPEEDS message will remain displayed after icing
encounter. Before next takeoff the message must be removed by
testing the Stall Protection System.
Do not start the engine until it has been checked that all ice deposits
have been removed from the air inlet.
Fuel and oil temperature limits are the same as those prescribed for
APU start.
Proceed with normal engine start.
In cold weather conditions, the usage of dual ignition (ignition switch
rotated to the ON position) is highly recommended for the first engine
start of the day or if the engine has not been run in the previous
90 minutes. This procedure may reduce the time from fuel introduction
to light-up.
As a reference, this procedure can be used for temperatures below
10°C, or at operator's discretion.
After a successful start the Ignition Switch must be switched to the
AUTO position.
If the engine does not start, ground heating may be necessary to warm
the nacelle, Air Turbine Starter (ATS) and Starting Control Valve
(SCV).
Do not allow the hot air from the ground cart to exceed 100°C (212°F),
as it may damage the components inside the nacelle.
