DESCRIPTION
Applicable to: ALL
The aircraft uses electrical heating for anti-icing each windshield and demisting the cockpit side
windows.
Two independent Window Heat Computers (WHCs), one on each side, automatically regulate the
system, protect it against overheating, and indicate faults.
Window heating comes on :
automatically when at least one engine is running, ‐ or when the aircraft is in flight.
‐ manually, before engine start, when the flight crew switches ON the PROBE/WINDOW HEAT
pushbutton switch.
Windshield heating operates at low power on the ground and at normal power in flight. The
changeover is automatic.
Only one heating level exists for the windows.

DESCRIPTION
Applicable to: ALL
Electrical heating protects :
‐ pitot heads
‐ static ports
‐ Angle-Of-Attack probes (AOAs)
‐ Total Air Temperature (TAT) probes
Three independent Probe Heat Computers (PHCs) automatically control and monitor :
‐ Captain probes
‐ F/O probes
‐ STBY probes
They protect against overheating and indicate faults.
The probes are heated :
‐ automatically when at least one engine is running, or when the aircraft is in flight.
‐ manually, when the flight crew switches ON the PROBE/WINDOW HEAT pushbutton switch
On the ground, the TAT probes are not heated and pitot heating operates at a low level (the
changeover to normal power in flight is automatic).
