scope:

This specification describes the hardware and utility software requirements for the enhanced Automated Radar Terminal System, ARTS IIA. This system is intended for use at airports experiencing a low to medium level of air traffic. The ARTS IIA system will provide for the decoding of secondary radar data, the generation of target reports from this date, the tracking of beacon targets and the display of associated alphanumerics identification, Mode C altitude, and ground speed data. In addition, all controlled Mode C aircraft will be monitored and warnings displayed for aircraft that are in conflict with other aircraft or the terrain. The system will interface with ARTCC facilities and will exchange air traffic control data on-line. A training mode will be provided so the system can be used to train air traffic controllers in a mixed live/simulated environment.
