This page provides general information on the datalink deployment in Europe covering deployment status, ATN Logon codes and FANS accommodation

Deployment Status

For datalink operations, there are two relevant implementing rules:

  • Amended Commission Regulation (EC) No 29/2009 (DLS IR), which covers the services to be provided and is applicable to both the ground and airborne sides;
  • Commission Regulation (EC) No 30/2009, which covers the automatic exchange of flight data between centres supporting datalink and is applicable only to the ground side.

These two regulations concern the ATN/VDL2 datalink.

The map below depicts the combined ground implementation status (May 2023) for the two above datalink regulations.


For the DLS IR (IR 29/2009) there are Deployment actions on 3 ANSPs to deploy DLS: Greece, Malta and Norway

For the Logon Ground Transfer (LOF/NAN) (IR 30/2009) there are Deployment actions on 7 ANSPs to complete automated logon transfer with all adjacent centers operating datalink: Croatia, Ireland, France, Poland, Portugal, Slovakia and UK.

For the airborne side, considering the declarations in the flight plans filed by the operators with NM, the equipage is above 80%.

ATN Logon Codes

For the ATN/VDL2 datalink, the a/c needs to initiate the datalink connection by connecting to the appropriate ground ATS cenrtre (ATSU) using the dedicated address of the intended ground centre. These addresses, also referred to as ATN logon addresses, NSAP addresses or Ground Facility Designators, are specified and maintained in the ICAO EUR Doc 028 (EUR NSAP Address Registry) document.

The map below consolidates the active ATN Logon addresses in the European airspace.


Future evolution of the active codes list will include the use of additional codes expected as follows:

  • LYBA (for Serbia & Montenegro) - planned for Q1 2024
  • EGII (for single UK code)
  • EDMM (for Germany/Munich)
  • ENOS and ENSV for Norway
  • LGGG and LGMD for Greece

The dates of when these codes will be activated are being consolidated.

FANS Accommodation

In addition to ATN/VDL2 datalink, 5 European centres (EGTT, EGPX, EISN, GCCC and LRBB) also accommodate FANS datalink. It is noted that the use of ATN is recommended over FANS in the European airspace in line with the regulation mandating the ATN/VDL2 service only.

Information about deployment is also provided in the NM CNS dashboard.
