The FDIO system is a subelement of the En Route Air Traffic Control Systems element of the NAS communications system. FDIO provides terminal and en route air traffic controllers with direct user input/output of flight plan and flight movement information and updates. FDIO replaces existing Flight Data Entry and Printout (FDEP) and Flight Strip Printer (FSP) systems, and also extends flight data services to terminal locations not presently served by FDEP. The FDIO system concept evolved from the need to increase the reliability and maintainability of the present system. Increases in flight traffic and resultant data loads have caused delays in the processing of data sent to and from FDEP sites, and to FSPs. FDIO will duplicate all of the functions of the FDEP and FSP system while providing extended capabilities. Flight strips will be displayed, as they are in the current system, by printing on the FAA flight strip forms. A CRT capability will be included as a function in all sites. Where no CRT is used, the display for message composition will be an Remote Flight Strip Printers (Terminal) (RFSP(T)). A keyboard will provide for data entry and error display as in the current system. Two central control units will be used at each Central Computer Complex (CCC) and one remote control unit at each FDEP site. |
