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.
3. Primary objective of Air Traffic Control is to prevent collisions between aircraft. In order to achieve this objective, the Air Traffic Controller issues clearances to provide safe separation between aircraft at any given time.Internationally agreed standards and procedures are followed to accommodate the aircraft movements in a safe and orderly manner.. Aviation has come a long way since the days when safe operation between aircraft was based purely on the 'SEE AND BE SEEN' principle. With the aircraft closing speeds in excess of 1000 mph, and increasing density of air traffic, the impracticability of reliance upon such a system is obvious. 2.
