Airspace Configuration and Separation Evaluation--Configuration and Procedures--Terminal ATC Digital Display System Errors,ARTS III.

摘要

The major position and separation errors associated with the digital data provided to the radar controller by the Automated Radar Terminal System (ARTS III) are quantitatively assessed to provide the basis for specifying the air traffic control separation minima in ARTS-controlled airspace. The National Aviation Facilities Experimental Center provides a Terminal Automation Test Facility at the Atlantic City Airport with a full complement of technical support facilities and engineering staff; here, an extensive series of live and simulated flight tests were conducted. The methodology, results, and conclusions of this effort are discussed. The results indicate that 99.9 percent of the overall range and azimuth errors can be expected to fall within + or - 0.16 nmi and + or - 1.43 deg, respectively, about their mean errors with a confidence of 90 percent. These errors are less than those generated in trying to read position from the radar displays. The ARTS III Radar Beacon Tracking Level system reported on herein utilized existing prototype hardware and software as available in early 1974. Many of the capabilities described in this report have since been enhanced by a continuing development program. The reader is encouraged to inquire into the availability of any later reports pertinent to this system. (Author)
