• Abstract:
  The Federation Administration’s Air Traffic Control Organization Safety Management System (SMS) is ; designed to prevent the introduction of unacceptable safety risk into the National Airspace System. One of the ; most important safety metrics used in the Air Traffic Organization’s SMS is the rate and severity of air traffic ; control operational errors (OEs). While OE rates tell us about the frequency of occurrence, the rates in and of ; themselves do not provide a direct assessment of safety risk. Two additional metrics are proposed for inclusion in ; the Air Traffic Organization’s SMS. These include the probability of resolution (POR) index and the time-onposition ; probability (TOPP) index. Whereas the POR is a measure of OE containment (i.e., resolving a loss of ; separation before the situation worsens), the TOPP is a measure of the occupational risk of an OE occurring due ; to traffic exposure. In this report, each metric is mathematically developed and empirically evaluated using ; archival en route data. ; In Study 1, the utility of the POR is evaluated based on 1293 OEs extracted from an en route OE research ; database for the period May 1, 2001 to May 31, 2003. ; In Study 2, the utility of the TOPP is evaluated based on 1,397,206 time-on-position entries from six en route ; centers for the 2006 calendar year. The results of both studies are discussed within a SMS framework.
