Welcome to the wiki of the EUROCONTROL NM Datalink Activities

The purpose of this wiki is to share information and raise awareness for the stakeholders of the VDL2/ATN datalink deployment in Europe.

The wiki covers the main activities of the EUROCONTROL NM datalink team. There are three main areas of activities, as follows:

In relation to the above activities, the EUROCONTROL NM datalink team facilitates the two European datalink stakeholder groups:

  • the Datalink Performance Monitoring Group (DPMG) and
  • the Datalink Support Group (DSG)

DPMG and DSG together address all aspects of datalink operations and deployment of VDL2/ATN datalink in European airspace. The DPMG and DSG meet twice a year. Information is shared with DPMG/DSG members via dedicated Onesky extranet sites. This wiki is intended to support the broader data link community.


Information on the general NM datalink activities is also available on the EUROCONTROL web site.


A template of questions for operators/crews has been developed in order to help target and expedite the investigation/analysis. You can access the questions by clicking in this link.
