System Safety Study of Minimum TCAS II (Traffic Alert and Collision Avoidance System) for Instrument Weather Conditions.

Abstract

An analysis of the air traffic environment in Instrument Meteorological Conditions (IMC) was conducted to identify those characteristics that have an impact on the level of safety provided by the Traffic Alert and Collision Avoidance System (Minimum TCAS II), and that differ from those characterstics under the more predominant visual conditions. The characteristics assessed include the fraction of aircraft equipped with altitude reporting transponders, the proximity of aircraft operating in these conditions, and the nature of the aircraft maneuvers. The study also extends the analysis of the level of safety provided by TCAS to include interactions with the air traffic control system. Interactions assessed include the compatibility of TCAS maneuvers with the ATC system and the potential for a domino effect wherein a TCAS advisory might create a new conflict. Originator-supplied keywords: Chicago O'Hare Terminal Area, Instrument Meteorological Conditions (IMC), near-Midair Collisions (NMAC), TCAS, System Safety.
