The purpose of this wiki is to support the sharing of information between the stakeholders of the Data Link Performance Monitoring Function (DPMF). The DPMF was established in response to the allocation of roles by the European Commission to the various European organisations. The purpose of the DPMF is to monitor the performance of the European data link system to allow stakeholders to understand how well the system is performing and to provide insight as to why the system is performing the way it is. It is intended to support many different stakeholder communities and as such will provide performance data at different levels of detail and from different perspectives. It does not address the monitoring of radio interference on the frequencies used by data link; this is the responsibility of the Network manager Radio Frequency Function. The work of the DPMF is overseen by a stakeholder consultation group called the Data link Performance Monitoring Group (DPMG) which meets twice a year. Information is shared with DPMG members via a Onesky extranet site. This wiki is intended to support the broader data link community.
In addition to the DPMF activities, EUROCONTROL NM supports joint investigations of reported issues together with relevant stakeholders and continues to support interop testing in particular for AOs and ANSPs.
Information on the general NM datalink activities is available on the EUROCONTROL web site.
