Welcome to the wiki of the NM Data link Performance Monitoring Activities
This wiki replaces the former CRO wiki

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.

Note EUROCONTROL continues to support interop testing and information is provided on this site for convenience although it is not part of the DPMF activities.

The Role of the DPMF

The main tasks of the DPMF are as follows:
  • Publication of regular performance reports. The DPMF publishes monthly high level performance reports as well as periodic reports from specific monitoring flights undertaken twice a year.
  • Ad-hoc performance analysis. DPMG members may request a specific performance analysis from the DPMF. These reports are intended to allow stakeholders to compare performance of their own business and compare it against an overall aggregated performance level.
  • Forecasting. The DPMF is tasked with forecasting the future performance of data link.
  • Stakeholder dashboard provision. Stakeholder dashboards are provided for both ANSPs and Aircraft Operators that allow them to analyse their own performance online. The dashboards are currently being redeveloped and improved dashboards are expected to be available in March 2019.
  • Performance investigations. The DPMF may undertake investigations in order to understand the underlying causes of performance problems.
  • Logon list management and avionic database maintenance. The DPMF manages a Logon list on behalf of some ANSPs that restricts which aircraft are allowed to logon to use data link. The DPMF maintains a database of the avionics installed on these aircraft to support the process.

The DPMF continues to provide a tool for Problem Investigation, but the responsibility for the investigation of problems now lies with the SESAR Deployment Manager.

Information about deployment is no longer provided on this wiki but may be found on the EU data link services web site.

Recent News...

  • User Satisfaction Survey Results 2019

1st July 2019: A summary of the results of the Data link User Satisfaction Survey have been published.

  • RIU-4010 Black Listing 2019

23rd April 2019: It has recently been proposed to remove all aircraft on the white list that are equipped with Rockwell Collins RIU-4010 which was black listed recently. Rockwell Collins however believe that only some configurations of aircraft with RIU-4010 should be black listed and are in the process of providing evidence to support that supposition and of finding a way for the DPMF to be able to identify more precisely the configuration that should be black listed. So the list of aircraft proposed for removal from the white list on the 20th June 2019 is likely to change. The DPMF will contact the registered operators of all affected aircraft once the situation is clarified.

  • The next DPMG meeting will be held on April 29th and 30th 2019 at EUROCONTROL Headquarters.
