Air Traffic Safety Electronics Personnel (ATSEP) / Communication, Navigation and Surveillance (CNS) specialists play a critical role in ensuring the safety, reliability, and continuity of air navigation services. They are responsible for the installation, operation, monitoring, and maintenance of CNS infrastructure such as radars, navigational aids, data links, and voice communication systems.
By ensuring high system availability, integrity, and compliance with ICAO standards, ATSEP/CNS professionals directly support safe, efficient, and uninterrupted air traffic operations in both civil and military aviation environments.
