Claim 14:
15. A windshield wiper system for use on a windshield of an aircraft, the windshield wiper system comprising:
a wiper comprising a wiper arm and a wiper blade coupled to a first end of the wiper arm;
a nozzle coupled to the wiper blade, wherein the nozzle is configured to dispense a fluid;
an actuator comprising an output shaft, wherein the output shaft is coupled to a second end of the wiper arm and the actuator is configured to rotate the output shaft to sweep the wiper arm and wiper blade across the windshield of the aircraft;
a controller electrically coupled to each of the actuator, a user interface, and a fluid control unit wherein the controller is configured to:
send electrical signals to and receive electrical signals from the actuator to control rotation of the output shaft of the actuator;
send electrical signals to and receive electrical signals from the fluid control unit to control operation of the fluid control unit; and
receive electrical signals from the user interface indicating an action to be performed by the controller; and

a plurality of fluid sources fluidly coupled to the nozzle through a fluid line, wherein each of the plurality of fluid sources is configured to dispense a different fluid through the nozzle, wherein the fluid dispensing from the nozzle can be selected from two or more of bleed air, water, windshield cleaning fluid, or chemical rain repellant, and wherein the user interface is configured to permit a user to choose which of the different fluids is dispensed through the nozzle.
