Claim 9:
10. A method of operating a windshield wiper system for use on a windshield of an aircraft, the method comprising:
transferring, by a controller, a command signal to an electrically coupled fluid control unit to activate the fluid control unit;
transferring, by the fluid control unit, a fluid from a fluid source through a fluid line to a nozzle coupled to a wiper blade;
dispensing, by the nozzle, the fluid onto the windshield of the aircraft;
receiving, by a user interface, input from a pilot or co-pilot;
transferring, by the user interface, a command signal to the electrically coupled controller indicating an action to be performed by the controller; and
transferring, by the controller, a command signal to the electrically coupled fluid control unit to activate the fluid control unit;
wherein the wiper blade is coupled to a first end of a wiper arm and an actuator comprising an output shaft is coupled to a second end of the wiper arm, and wherein the actuator is configured to rotate the output shaft to sweep the wiper arm and the wiper blade across the windshield of the aircraft;
wherein the fluid dispensing from the nozzle is bleed air, water, windshield cleaning fluid, or chemical rain repellant;
wherein:
the nozzle is removable from the wiper blade;
the nozzle includes two sides and at least one output port on each of the two sides; and
the nozzle is configured to dispense fluid from the at least one output port on each of the two sides of the nozzle; and

wherein each wiper blade includes a plurality of nozzles coupled to the wiper blade, and wherein each one of the plurality of nozzles is spaced equidistance apart along a length of the wiper blade.
