POM DESCRIPTION
Ice Inspection Lights
The aircraft is equipped with a single ice inspection light on the left side
of the fuselage. An optional right side ice inspection light is also
available. The light will automatically illuminate at night when ice is
detected or can manually be commanded on or off. When commanded
on, the light illuminates the on-side leading edge of the wing.
Indications
Status of the ice protection systems is provided on the ICE
PROTECTION synoptic page
Wing Ice Protection System
WAIV and WAIXV positions are shown on the ICE PROTECTION
synoptic page, as are L and R wing temperature. The temperature is
normally an average of the inboard and outboard temperature sensor
readings but will change to the lowest reading if an under-temperature
reading is detected or the highest if an over-temperature reading is
sensed. A green leading edge indicates that the system temperature is
high enough to provide anti-icing. The leading edge changes to an
amber color if the temperature is too low to provide anti-icing or is over-
heating. The wing is white when warming up or commanded off.
Engine Inlet Ice Protection System
L and R CAIV positions are shown on the ICE PROTECTION synoptic
page, as is inlet temperature. A green inlet indicates that the system is
commanded on and the temperature is high enough to provide anti-icing.
This is also indicated by a white A/I icon on the EIS. The inlet changes
to an amber color if the system is unable to provide anti-icing. A L(R)
ENG ANTI-ICE ON status CAS message is posted when the system is
commanded on.
