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

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.
