What is CNS/ATM?

The tremendous growth in air traffic presents increasing challenges for air traffic service providers, air carriers, and the military. Such growth is straining airspace capacity and airport resources. The air traffic system requires significant upgrades to increase system capacity and flight efficiency while continuing to meet flight safety standards. The International Civil Aviation Organization (ICAO), Federal Aviation Administration (FAA), and other civil aviation authorities (CAA) plan to implement a new air traffic architecture to meet this need. This new architecture takes advantage of emerging technologies in communication, navigation, and surveillance to improve air traffic management. Dynamic routing gives operators the freedom to choose their own routes, speeds, and altitudes in real-time, thus providing Visual Flight Rules (VFR) flexibility with Instrument Flight Rules (IFR) protection and separation and a shift from Air Traffic Control (ATC) to Air Traffic Management (ATM). The civil aviation community refers to these changes as Communication, Navigation, Surveillance/Air Traffic Management (CNS/ATM). The United States Department of Defense (DoD) has established the CNS/ATM program to modernize its aircraft. The ability to reduce aircraft separation and implement other new ATM procedures while maintaining or improving safety standards is enabled by the use of new technology. The most critical technology elements of the new CNS/ATM environment are satellite-based navigation, increased use of data links rather than voice for pilot/controller communication in oceanic/remote airspace as well as en route and terminal environments, and improved surveillance that enhances both ground and cockpit situational awareness. If aircraft are not equipped with the appropriate new technologies, they may not be able to operate in airspaces where new separation standards and ATM procedures are implemented by civil aviation authorities, and may therefore be excluded from those airspaces. For DoD aircraft to operate in this new environment, significant modifications to existing aircraft must be accomplished. The CNS/ATM group of technologies provides the means to achieve the operational capabilities required thus enabling unrestricted global operations.
