CNS/ATM SYSTEMS

ICAO DEFINITION FOR
CNS/ATM SYSTEMS
 
DEFINITION
Communications, navigation, and surveillance systems, employing digital technologies, including satellite systems together with various levels of automation, applied in support of a seamless global air traffic management system.
 
STRATEGIC VISION
To foster implementation of a seamless, air traffic management system that will enable aircraft operators to meet their planned times of departure and arrival and adhere to their preferred flight profiles with minimum constraints and without compromising agreed levels of safety.
 
FUTURE BENEFITS
CNS/ATM systems will improve the handling and transfer of information, extend surveillance and improve navigational accuracy. This will lead to, among other things, reductions in separation between aircraft, allowing for increased airspace capacity. Advanced CNS/ATM ground-based systems will exchange data directly with flight management systems aboard aircraft through data link. This will benefit the ATM provider and airspace user by enabling improved conflict detection and resolution through intelligent processing, providing for the automatic generation and transmission of conflict free clearances, as well as offering the means to adapt quickly to changing traffic requirements. As a result, the ATM system will be better able to accommodate an aircraft’s preferred flight profile and help aircraft operators to achieve reduced flight operating costs and delays.
