1. 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 one of a plurality of fluid sources through a fluid line to a nozzle coupled to a wiper blade; and
dispensing, by the nozzle, the fluid onto the windshield of the aircraft;
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 controller is electrically coupled to the actuator, the fluid control unit, and a user interface, and 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 dispensing of fluid through the nozzle; and
send receive command signals from the user interface indicating an action to be performed by the controller;

wherein each of the plurality of fluid sources is configured to dispense a different fluid through the nozzle and the user interface is configured to permit a user to choose which of the different fluids is dispensed through the nozzle.
