Abstract : The purpose of this report is to characterize the performance of the Traffic Alert and Collision Avoidance System (TCAS) logic which was developed by the Mitre Corporation. The evaluation was based on baseline logic documentation and logic changes made between January to October 1981. The report is the first part of a three-volume series and reflects the evaluation of logic performance using the Fast-Time Encounter Generator as the logic test bed for unequipped threats. The study was conducted in two phases. The initial phase addressed the identification and correction of logic flaws. After the improvements in the logic were coordinated with are provided by Mitre, the second phase assessed the TCAS logic performance for a wide variety of two-aircraft encounters. The report identifies the logic deficiencies and the results of the analysis. In general, TCAS logic performance was excellent. (Author)
