 C. Hydrophobic Coating A hydrophobic coating can be applied on each windshield to repel rain. The hydrophobic coating is used instead of the rain-repellent fluid system.
 NOTE : When there is a hydrophobic coating on the windshield, the rain
____ repellent fluid must not be applied on the windshield.

 3. System Description
__________________
 A. Wipers
 Two totally independent sub-systems are provided:

 -CAPT sub-system (left windshield),

 -F/O sub-system (right windshield).
 A two-speed electric motor serves to operate each arm/blade assembly.
 Each sub-system ensures that clear vision is maintained through the
 windshield during all rain conditions and during the following flight
 phases:

 -taxi,

 -takeoff,

 -approach,

 -landing.
 Control switches located on the overhead panel are provided for each
 wiper to select the wiper speed:

 -slow operation (SLOW position),

 -fast operation (FAST position),

 -stop (OFF position) in a parking position of the arm/blade assembly.
 Each sub-system comprises the following components

 -------------------------------------------------------------------------------ITEM DESIGNATION QTY COMMENTS -------------------------------------------------------------------------------
1 Motor converter 1  Motors identical, converters symmetrical
 2 Arm (rigid) 1 Identical for
 CAPT and F/O
 3 Blade 1 Identical for
 CAPT and F/O
 4 Control switch 1 Identical for
 CAPT and F/O

 B. Rain Repellent
 (1)
 The rain repellent fluid used is packaged in a nitrogen pressurized can. The nitrogen pressurizes the lines of the rain repellent system.

 (2)
 The can is directly fitted to the rain-repellent fluid gage, thus enabling the sealing valve of the can to open.

 1EFF : ALL 1 30-45-00Page 11 1 1 May 01/05R 1 1 1CES 1

 (3)
 The components given below are located on the side of the rain-repellent fluid gage:

 -
a pressure gage indicating the pressure in the system and thereby the remaining fluid,

 -
a purge pushbutton used to purge the lines when the can is
 replaced.

 (4)
 Lines release the fluid to each of the two spray systems which operate independently.

 (5)
 A fluid spray system is provided for each windshield. It incorporates the components given below:

 -
a solenoid valve (time controlled),

 -
a control pushbutton switch,

 -
a spray nozzle.

 (6)
 A CAPT(FO) RAIN RPLNT pushbutton switch, located in the cockpit, serves to control the system. Upon actuation of the pushbutton switch, the time-controlled solenoid valve of the associated system enables fluid release to the spray nozzles for a limited period. To initiate a new cycle, it is necessary to release then to push again the control pushbutton switch.
