A proof-of-concept project showing feasibility of a semiautomatic system integrating ils, mls and en route navigation for light aircraft is proposed. The purpose of the system is to increase navigation presision and s d simplicity, especially in the rnav and mls environments. Thesystem would also enhance air traffic control capacity, reduce pilot workload, and improve safety margins. Information would be presented in an integrated, easy to interpret form and require minimum pilot interaction reducing the chance for imput error. The feasibility of integrating a remote mls receiver module with a central processor system used for en route navigation will be examined, and the potential streamlining of harware and reduction in power consumption that might be possible with central control, processing, and display will be investi igated. Potential general aviation applications include pr private, corporate, and air taxi services operating aircraftunder instrument flight rules (ifr). Government applicationsinclude airborne navigation facility check-flights and search-and-rescue operations.
