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. 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. Nota Bene. As from 24th August 2021 MUAC/EDYY will only support CPDLC via the ATN – legacy FANS 1/A support will cease as of then.

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. Information about deployment is no longer provided on this wiki but may be found on the NM CNS dashboard.
