  • Communication,
  • Navigation,
  • Surveillance and
  • AirTraffic Management systems/equipments.

What IFATSEA concerned all these infrastructure are safety relevant, several even safety critical.

These equipment should be certified by ATSEP, which currently isn't the case for all equipment.

Navigation equipment like DVOR, ILS and other are certified by regular Flight Inspections.

The certification of certain equipment is currently country depended.

Next picture views the CNS/ATM infrastructure within ANS as definition in European context (EC regulations).

ATSEP - Air Traffic Safety Electronics Personnel

Air traffic safety electronics personnel (ATSEP) is an ICAO term for the technical staff involved with the creation and support of the ground-based electronic hardware and software systems used to support air navigation and Air Traffic Management.

Often employed by Air Navigation Service Providers, ATSEPs are mainly engineers, technicians, hardware and software specialists who are responsible for the specification, procurement, installation, integration, calibration, maintenance, safety assurance and monitoring of these systems. The equipment ranges from discrete specialist electronic systems to Commercial-Off-The-Shelf computer hardware running specialist software designed and maintained to provide a high critical safety-of-life service to aircraft. The systems provide Communication and Navigation services for aircraft, Surveillance (e.g. Radar), Flight Data Processing and supporting tools for Air Traffic Controllers.

The principal duties of the ATSEP are (source ICAO Training manual doc 7192 E2):

 Performing maintenance on CNS/ATM system/equipment which include:

  • Calibrating flight and ground radio navigation aids;
  • Certification of CNS/ATM system/equipment;
  • Modification of operational CNS/ATM equipment;
  • Corrective maintenance;
  • Preventive maintenance.
  • Performing installation of CNS/ATM system/equipment.
  • Management, monitoring and control of operational CNS/ATM system/equipment.
