 WING ANTI-ICE CONTROL MODULE (P5-11) - ADJUSTMENT/TEST
______________________________________________________
 1.  General_______
 A.  This procedure has tasks to test the P5-11 Wing Anti-Ice Module. The tests make sure the P5-11 module operates correctly after installation. The test procedure gives the module a signal from each source. Then, you look at the lights on the module to see that the module operates correctly.
 B.  This procedure has two tasks.
 (1)  
The first task does does a test of the inputs from the wing TAI valves and the throttle levers.

 (2)  
The second task does a test of the inputs from the thermal switches.

 TASK 30-11-41-705-001
 2.  Do a Test of the Wing Anti-Ice Control Module (P5-11)_____________________________________________
 A.  General
 (1)  In this procedure, 'TAI' replaces 'thermal anti-ice'.
 B.  Special Tools and Equipment
 (1)  
Protractor - 4MIT65B80307-1 or F52485-500

 (2)
