ABSTRACT:
An apparatus on an aircraft provides external aircraft lighting which incorporates a coding system to facilitate visual identification of the aircraft. The lighting apparatus includes a plurality of optically-coupled components for generating, transmitting and projecting a laser beam. The components are installed in an interior compartment of the aircraft and are operable to generate the laser beam, to transmit the generated laser beam to a location adjacent to an exterior portion of the aircraft fuselage, and to project the transmitted laser beam in a predetermined direction from the exterior portion of the aircraft and in a predetermined pattern. The coding system incorporated by the pattern is based upon the properties of beam color, beam portion number and beam pulse frequency. Different values are assigned for these properties to code the different characteristics which can be used to identify the aircraft.
