Data transfer and display equipment for a proposed system of air traffic control

IN 1947, a group representing all phases of the aviation industry met as Special Committee 31 of the Radio Technical Commission for Aeronautics (RTCA). Their purpose was to bring order out of a chaos where many different systems of air navigation and air traffic control were being proposed and developed to satisfy the same need. This group evaluated the existing and proposed systems and formulated a long-range plan for orderly progress toward the development of a common system to serve all nontactical military air traffic and all civilian aircraft.
