Article: View on Regulations Concerning Communication, Navigation and Surveillance (CNS) Service in Civil Aviation

Abstract

This article presents the overall regulatory environment related to the provision of Communication, Navigation and Surveillance (CNS) services in civil aviation. Through the evolution of international standards established by the Chicago Convention and through the development of CNS services, insight was given into the importance ofCNSservices in ensuring safe and efficient air traffic.The functions of the CNS system are presented and explained, as well as the key contribution of international organizations such as ICAO and International Telecommination Union (ITU) in the development of these services. Through research on the complexity of CNS services, the evolution in the past decades, the text explains the legal aspects related to civil aviation, but also international telecommunications and space activities that are related to civil aviation. The legal framework that regulates space activities, that is, the use of satellites in air traffic management, is especially covered. airspace (CNS/ATM). ICAO initiatives are additionally addressed, particularly the integration of satellite technology through Future Air Navigation Systems (FANS) and the legal significance of resolutions such as A32-19 on Global Navigation Satellite System (GNSS) services from the 1998 Rio Conference. The narrative further examines the implementation of CNS/ATM concepts, legal considerations in air-ground communications, harmonization efforts, and the consolidation of resolutions for effective global implementation. The text concludes by highlighting ICAO’s ongoing commitment to align technological advancements with legal frameworks, promoting the seamless utilization of CNS/ATM systems worldwide. The significance of regional and national regulations, with a focus on European CNS regulations, is underscored for enhancing air traffic safety and fostering the development of CNS services.
