GENERAL
Thermal antiicing,
electrical antiicing,
ice detection and alerting systems are provided for airplane
ice and rain protection. Selections for antiice
functions are made on the ANTIICE
panel, located on
the overhead panel.

WING XBLEED
Ice Detection
Independent ice detection probes (2), located on the fuselage, sense the formation of ice. If ice is
detected, the ice detectors automatically turn on the electrical heat to the various probes, signalling
the Bleed Management Controllers (BMC) to activate wing antiice
and operate a relay in the
ANTIICE
Control panel to activate cowl antiice.
Pneumatic AntiIcing
Hot air antiicing,
provided by engine bleed air, through piccolo ducting, wing antiice
valves and cowl
antiice
valves, prevents the formation of ice on the wing leading edge, slats and the engine intake
cowls.
Electrical AntiIcing
Electrical antiicing
is provided for Pitot Static Probes, Ice Detectors, Total Air Temperature (TAT)
Probes, Heater/Brake Temperature Monitoring Units (HBMUs) and Angle of Attack (AOA) Vanes.
Selections for the Pilot’s and Copilot’s Windshields and Side Windows heating, are made on the
WINDSHIELD HEAT panel, located on the overhead panel.
