WINDSHIELD ICE AND RAIN PROTECTION
DESCRIPTION
The windshield and side window heating system includes two windshields and two side windows that contain embedded
heater elements and sensor elements. The windshield and windows are treated with a rain resistant coating
COMPONENTS AND OPERATION
WINDSHIELD AND SIDE WINDOW HEATING
The windshield heater elements are segmented into three sections, and allow for concentration of heating in a smaller area
of the windshield in order to allow visibility in severe icing conditions. The side window heater elements have no segmen-
tation. Flight in super-cooled large droplet icing (SLD) conditions may, but not necessarily be indicated by ice accretion on
side windows. Temperature controllers, one for each windshield and window, monitor the electrical resistance of the tem-
perature sensors that are embedded in the glass. The temperature controllers cycle power on and off to maintain a prede-
termined glass surface temperature.
CONTROL SWITCHES AND FUNCTION
Switches located on the ANTI-ICE panel control windshield and window heat. The L WSHLD/WINDOW switch controls
the left windshield and left window. The R WSHLD/WINDOW switch controls the right windshield and right window.
Overheat protection circuits for each windshield or window remove power from the affected surface during an overheat
condition. Selecting the L (R) WSHLD/WINDOW off de-energizes the applicable windshield and window and resets the
temperature controller.
