 FLIGHT COMPARTMENT WINDOW ANTI-ICING - ADJUSTMENT/TEST
______________________________________________________
 1.  General_______
 A.  This procedure contains two tasks. The first task is an operational test of the window anti-icing system for the flight compartment. The second task is a test of the resistances of the window heater element loop.
 B.  The tests are done on the flight deck and in the main E/E equipment bay, with only the test equipment on the airplane.
 C.  This procedure includes the resistance values for the window heater element. You can use these resistance values to find if the window heating element loop has the correct specification. These values are only for checks made across the window heater terminals.
