One of the remaining sources of mid-air collision risk is encounters between aircraft that are equipped with Traffic Alert and Collision Avoidance System (TCAS) and non-TCAS-equipped General Aviation (GA) aircraft. Equipping GA aircraft with a collision avoidance system may further reduce the mid-air collision may further reduce the mid-air collision risk in the National Airspace System (NAS). A critical design decision for a GA aircraft collision avoidance system is the level of coordination between the system and TCAS on TCAS-equipped aircraft. This report investigates the performance of varying levels of coordination: full coordination where the system directly coordinates with TCAS, responsive coordination where the system only responds in TCAS, and no coordination. Results from this study show that equipping GA aircraft with TCAS is acceptable if the GA pilot response rate is high and vertical capability of the aircraft can achieve TCAS advisories. A responsive coordination strategy performs well regardless of the GA pilot response rate. Lasty, GA aircraft should not be equipped with the TCAS logic without a coordination capability.
