Aircraft communications are being expanded; in fact, in recent years a new abbreviation has surfaced. CNS ATM stands for âCommunication, Navigation, and Surveillance and Air Traffic Managementâ which was created to support modernization of the dated and overload prone Air Traffic Control system. Aircraft that are intended to transport passengers are equipped with radios that enable analog voice communications. This is currently and will be for the foreseeable future the primary means for pilots to communicate withdifferent entities of the Air Traffic Control (ATC) system.
1 Traffic collision avoidance system (TCAS), which actively interrogates the transponders of other aircraft and negotiates collision-avoidance tactics with them in case of a threat. 2  TCAS systems are relatively expensive, and tend to appear only on larger aircraft. Obstacle Collision Avoidance System is a ground based system that uses a low powered radar mounted on or near the obstacle. 2  The radar detects aircraft in the proximity of the obstacle and firstly warns aircraft via flashing medium intensity lights and secondly warns aircraft of the obstacle via a VHF broadcast.
