摘要：	This report documents the Lincoln Laboratory evaluation of the Traffic Alert and Collision Avoidance System II (TCAS II) logic version 7. TCAS II is an airborne collision avoidance system requited since 30 December 1993 by die FAA on all air carrier aircraft with more than 30 passenger seats operating in the U. S. airspace. Version 7 is a major revision to the TCAS II logic consisting of mote than 300 separately defined changes affecting all major TCAS areas (surveillance, CAS logic and displays/aurals). Lincoln Laboratory evaluated the logic by examining approximately two million simulated pairwise TCAS-TCAS encounters, derived from actual trades recorded in U. S. airspace. The main goals of the evaluation were: (1) to study the performance of die new TCAS-TCAS coordinated reversal logic; (2) to detect and explain any areas of poor performance; (3) to examine the performance of the version 7 logic for the 30 Representative NMACs identified during the 6.04a logic evaluation; and (4) to understand die limitations of the logic by analyzing every version 7 NMAC. Five Lincoln Laboratory analysis programs written for previous logic evaluation work were updated and new software was written to aid in the evaluation of TCAS-TCAS sense reversals. There were four phases of the evaluation corresponding to the above goals. For each phase the report gives an overview of the evaluation approach taken and a description of the results. An overall summary and perspective on die evolution of the TCAS II logic are given at the end of the report.
