An aircraft windshield wiper system includes a wiper arm, a wiper blade coupled to a first end of the wiper arm, and an output shaft coupled to a second end of the wiper arm. The wiper blade is configured to clean water, dirt, and other debris from the windshield of the aircraft. The output shaft is configured to rotate and cause the wiper arm with the coupled wiper blade to sweep across and clean the windshield. A sensor and a trigger are coupled to an actuator to ensure accurate sweep angle and parking position of the wiper arm and wiper blade.
