Tests were conducted at the National Aviation Facilities Experimental Center using the Model A traffic control simulator to explore the use of digital high speed communications in the air traffic control environment. Simulated input and output devices were provided for use by the controllers working at an en route position so that the controllers were able to select, compose, and transmit traffic control messages to the simulator pilots by other than the usual voice methods. The results indicated that there are eight major categories of messages that are suitable for ground-to-air transmission using digital methods in lieu of voice. Three of these categories (altitude, frequency, and heading change instructions) require quick-action input keys for the controller and should be displayed to the pilot on a miniature 4-digit indicator in the cockpit. Such control instructions require priority handling and therefore need instantaneous pilot acknowledgement by voice. The other five categories involve clear text messages that should be displayed to the pilot on a cockpit printer. They are selected from computer storage and have a lower priority than the altitude and heading change instructions. Some input devices for text messages need to be tailored to match the airways structure of various en route sectors in which they are used. (Author)
