The Network Manager is now responsible for monitoring datalink performance in Europe’s air traffic management (ATM) network, Eurocontrol said. This builds on the recommendations from the Single European Sky ATM Research (SEAR) Joint Undertaking (JU) VDL Mode 2 Measurement, Analysis and Simulation Campaign — more commonly known as the ELSA project. It is also in response to the European Commission.
ATM stakeholders have formed a group, known as the Datalink Performance Monitoring Group (DPMG). The group decides on what to monitor and which types of report should be published, according to Eurocontrol. It reports to the Network Management Board and the Single Sky Committee via the Director Network Manager.
Eurocontrol said the DPMG’s main activities are to:
Eurocontrol said the first performance reports indicate that the datalink infrastructure needs “major enhancement” to meet required performance levels. However it is improving, as the provider-abort rate is at a historically low value of just under five provider aborts per 100 hours of CPDLC (controller-pilot data link communications) usage (against a target value of one), according to Eurocontrol.
Recent network manager stakeholder consultations have shown there is risk of a significant increase in the data transmitted by the new generation of aircraft, such as the A320neo in the short term, Eurocontrol said. Because of this, the network manager plans to reinforce its links with the aircraft operators and aircraft manufacturers to determine the optimum usage for different communication options for airline operation communications and air traffic control.
