Analysis of Automatic Aircraft Altitude Reporting Using the Air Traffic Control Radar Beacon System.

摘要

The report documents work measuring the degree of relative correspondence between simultaneous automatic aircraft altitude reports and oral altitude reports from pilots recorded on magnetic tape at two FAA terminal area ATC facilities and one enroute ATC facility. The frequency of occurrence of the resulting observed deviations between automatic and pilot reports are tabulated by deviation magnitude and by phase of operation (i.e.,climb,descent,and level) and control facility;probable causes of observed deviations are identified.
