Abstract:This report describes a concept for providing enhanced terminal information services (ETIS) to aircraft utilizing the ground-air-ground data link capability of the Discrete Address Beacon System (DABS). ETIS is envisioned as an eventual replacement for, and significant improvement to the Automated Terminal Information Services (ATIS) in use today. The initial step in developing the concept is the establishment of requirements for an ETIS system. This is followed by a determination of the information and data to be provided to the aircraft over the data link, and the probable sources of that data. An assumption is made that the availability of automated weather sensor systems of some form will coincide with implementation of ETIS. A detailed functional description of the system is then given, including system configuration, interfaces with other ATC automation systems, and hardware and software both at the airport and at the controlling ATC facility. Also discussed are message content and formats, controller and pilot display design considerations, criteria for dispatch of ETIS messages, and a number of operational considerations. The report concludes with several typical flight scenarios representative of different levels of aircraft, avionics, and pilot capabilities in an air traffic control environment where ETIS is implemented.
