Pilot performance research for TCAS

Three separate studies have been conducted to ascertain pilot responsiveness to advisories generated by the Traffic Alert and Collision Avoidance System (TCAS II). In the first of these, pilot responses to normal TCAS II resolution advisories were evaluated, while the second gave attention to amended advisories and the third to alternative display formats. Within this study's simulated conditions, pilots were able to respond to advisories quickly and accurately. The addition of a target vertical speed range on the resolution advisory display resulted in further improvements of pilot response and accuracy.
