A series of 24 two aircraft encounters were designed and executed to validate and verify the Change 6 Traffic Alert and Collision Avoidance System (TCAS)-II collision avoidance logic of February 1989. These tests were performed with several aircraft equipped with varying configurations of TCAS and Mode C. Technical Center pilots performed all of the logic test encounters. Technical Center and TCAS manufacturer company pilots performed the TCAS coordination test encounters. Industry pilots performed a pilot evaluation of the logic changes through execution of a subset of the encounters. The logic flight tests demonstrated that the computer simulations of the encounters were accurate. The Change 6 logic successfully resolved all tested encounters, including those which would have resulted in 'advisory invalid' enunciations in the Change 5 logic. The pilots generally accepted maneuvers suggested by TCAS as safe and appropriate for the flight geometries. The pilots did suggest improvements to the TCAS display logic, and many of these improvements were incorporated into the final Change 6 logic of September 1989. The encounters have been updated to include all changes included in the final Change 6 logic in the event that additional flight tests are desired.
