FACT-SHEET-The FAA's Air Traffic Modernization Program
The Federal Aviation Administration (FAA) is aggressively upgrading its air traffic systems to meet the challenges of the 21st century. The Display System Replacement (DSR) is a major part of that effort.
The FAA is responsible for the largest, most complex and safest aviation system in the world. It includes more than 18,000 airports, 470 air traffic control towers, 176 terminal radar control facilities (TRACONs), and 21 en route air traffic control centers.
In addition to DSR, other important systems are：
-"Host" computers-The FAA is replacing the "host" computer at all of its en route centers. The host processes flight plan and radar data and sends that information to controllers at the center and other air traffic facilities. Host replacement involves hardware only, no new software.
-Standard Terminal Automation Replacement System (STARS)-STARS will replace computers(hardware and software) at the nation's busiest airport terminals and pave the way for future upgrades. The new displays will help controllers handle traffic more efficiently while maintaining today's extraordinary level of safety.
-Wide Area Augmentation System (WAAS)-WAAS enhances signals from the Global Positioning system (GPS) to satisfy civil aviation navigation requirements. When the first phase of WAAS is operational in September 2000, pilots will be able to make precision GPS-guided landings throughout roughly half of the continental United States.
-Data Link-Data link is essentially airborne e-mail flowing between computers on the ground and in the cockpit. It reduces the time lag and chances of errors associated with voice communications. Data link can provide critical flight and weather information from various data bases directly to pilots. The technology already is being used to transmit pre-departure clearances to pilots.
