Abstract. In this paper we investigate the airborne collision avoidance system (ACAS) and its further development to enhance flight safety by expanding the functionality of the system TCAS II TCAS 2000. Automation and control functions and, in particular, the functions of preventing conflict situations in flight – one of the most effective ways of airborne and ground systems, avionics, providing a significant
increase in safety. In this article, we conducted a comparative analysis, which allows us to determine the benefits of TCAS 2000 compared TCAS II system in the future be used in the civil aviation of the Republic of Kazakhstan decent system that will ensure the safety and regularity of flight.

Key words: Airborne Collision Avoidance System (ACAS), Automation of management functions, issue only warnings about the traffic situation (Traffic Alert Only), warning zone (Warning Area) and the zone of increased attention (Caution Area).
