Description: Monitoring of Traffic alert and Collision Avoidance System (TCAS) performance has identified instances where flight crews responded in the opposite direction to that specified by TCAS when the resolution advisory (RA) was displayed by flight crews. These opposite responses where observed for RAs classified as Negative RAs by the collision avoidance system (CAS) logic, and are characterized by the fact the flight crew believes their response is correct, i.e., not opposite. This report presents the results of the Operations Working Group's (OWG) initial investigations, provides a definition of the factors the OWG believes will contribute to the opposite responses, and presents recommendations for future work to identify items that will improve pilot response to these types of RAs.
