AIR ROUTE SURVEILLANCE RADAR

This reproduces published FAA reference text for study. It does not replace the current official FAA publication or regulation.

Air route traffic control center (ARTCC) radar used primarily to detect and display an aircraft's position while en route between terminal areas. The ARSR enables controllers to provide radar air traffic control service when aircraft are within the ARSR coverage. In some instances, ARSR may enable an ARTCC to provide terminal radar services similar to but usually more limited than those provided by a radar approach control.
