GENERAL
General
The airplane ice protection systems employ
hot air and electrical heating for anti-icing
and anti-fogging functions. Rain removal is
accomplished by chemical repellent and
electrically operated windshield wipers.
Window Heat
Electrical heating provides heat for anti-icing
and anti-fogging of the pilot’s three
windshields, and anti-fogging for the
clearview and overhead windows.
Probe Heat
Electrical heating is used for anti-icing the
pitot tubes, static port areas, stall angle of
attack vanes, and ram air temperature
probe.
Airfoil Ice Protection
The airfoil ice protection system provides
anti-icing heat to the wing leading edge
slats, forward strakes, and to the air
conditioning ram air-scoop inlet in flight,
when the air foil switch and associated
pneumatic crossfeed valves are actuated.
De-icing is available for the horizontal
stabilizer leading edge by the tail de-ice
pushbutton. Heat is then diverted from the
wing leading edge slats and strakes to the
horizontal stabilizer. Tail de-icing is provided
for 2.5 minutes, and then flow is reverted
back to the wing slats and strakes again.
When air foil anti-icing is selected, tail de-
icing will automatically be selected every 15
minutes.
Forward strakes anti-icing is accomplished
through the same system as the wing
leading edge slats, and is controlled by the
same switch.
Clear Ice Detectors
Triangular decals, with a piece of parachute
cord attached, are installed on the upper
inboard surface of both wings. The purpose
of these decals is to assist the de-icing crew
during de-icing. If clear ice is present the
cords will remain frozen to the wing. De-icing
fluid should be applied until the cords move
freely. The triangles provide a secondary
visual reference as the edges of the triangle
will appear irregular if covered with clear
ice.
Engine Anti-Ice
Engine anti-icing is provided by
independent system, controlled by
individual switches located on the overhead
ice protection panel. Each engine provides
ice protection for the respective engine,
nose cowl, inlet bullet, and compressor inlet
guide vanes.
