ABSTRACT:
A laser guidance system includes at least two laser beam generating devices that generate a beam which reflects off a reflective surface positioned on the backside of a propeller blade in order to indicate to a pilot in which direction the aircraft has deviated from a desired flight course. The reflective surface is placed on an area near the tips of the blades of a single engine aircraft propeller to provide a display surface to reflect the laser beam to create a light spot. The laser beam directs light to the left or right side of the nose of the airplane onto the circular path the reflective surfaces made when the propeller spins. The resulting light spots indicate which direction, left or right, a pilot should maneuver the aircraft to follow a desired flight course.
