An electronic system for air traffic control information

A digital information processing system has been built for handling and storing flight plans and weather information. Messages are received and sent out by the system automatically over standard teletype lines. Requests for stored information and directions to change it are also transmitted by teletype. This system is capable of being connected in common with other similar systems by a teletype network with automatic switching facilities. It was designed to form part of the common system for air traffic control. Received messages are randomly filed in a magnetic drum store and subsequently found by means of their contents. The system has a complete logical plan which is designed to give a specific result for each possible action and to cause any questionable or obviously erroneous received messages to be printed out for supervisory review.
