Integration TCAS, FMS, and ATC system

According to one of the rules of technical system, development systems should integrated in one. At present, TCAS II (Traffic collision avoidance system) works independently from the aircraft system and gives only vertical RA (Resolution advisory) during traffic conflict. FMS (Flight management system) has control autopilot with parameters such as heading, VS (vertical speed), IAS (indicated air speed). The integration TCAS, FMS, and ATC (air traffic control) system in one gives an opportunity to an aircraft having full information and control in the air transport system with navigation, separation, operation, etc.
