Successful Radio Operator Simulator (RO-FDS) launch at Isavia

Isavia has implemented a new Radio Operator Simulator from Tern Systems.  The simulator is used to train users on the Tern Radio Operator Flight Data System, RO-FDS, which is operated by Isavia’s Gufunes Communications Centre in Reykjavik, Iceland.

In very broad terms, the operations of the Gufunes Communications Centre can be divided into two main areas. Communications with aircraft in flight (Aeronautical Mobile Service [AMS]) and operation of an AFTN/CIDIN message switch (Aeronautical Fixed Service [AFS]). The AFTN/CIDIN switch (TAMS from Tern Systems) forms part of the international aviation-related message distribution system. The switch in Gufunes is connected to comparable switches in London, Norway, Canada and Greenland. In Iceland it is connected to the Area Control Centre, Keflavik Airport and various aircraft operators‘ facilities. Operational management of the system is in the hands of a watch officer in Gufunes with technical support provided by the Air Navigation Division.

The radio operator uses the RO-FDS to act as an intermediary between the controller and air crew. The information exchanged includes:

  • Position reports at cleared reporting points
  • Pilot requests for changes in altitude, speed or route Air traffic control clearances from the area control centre
  • Weather information to and from pilots
  • Information provided to Airline OperationsCentres (AOCs)

The Communications Centre in Gufunes provides services 24 hours a day on HF and VHF GP frequencies. The Centre has a total of eight working positions to handle air/ground comm-unications.  Approximately 40 flight information officers, divided into 5 shift teams, work in the Communications Centre at Isavia.
