ToR RMT.0524

Data link services

The European Aviation Safety Agency’s (EASA) analysis of the technical issues observed during the deployment of Regulation (EC) No 29/2009 resulted in various recommendations which were further considered during the data link services (DLS) extensive review and testing conducted by Sesar Joint Undertaking (SJU). The resulting report, known as Enhance Large Scale ATN deployment (ELSA) report, included additional recommendations, some being regulatory in nature. Based on those recommendations and as requested by the European Commission, this rulemaking task (RMT) will address these regulatory recommendations to support the datalink operations as required by Regulation (EC) No 29/2009. It will also determine the regulatory needs to support the ELSA Model D multi-frequency implementation, the identification and development of an ‘end-to-end certification/validation’ framework and the clarification of the notion of ‘best in class’ performance and the related avionics improvements.

Furthermore, to improve the predictability of the aircraft trajectory leading to less tactical interventions and improved deconfliction, this RMT addresses elements of the ‘Pilot Common Project’ (PCP) air traffic management (ATM) functionality 6 requirements (‘Initial Trajectory Information Sharing’) and, in particular, the requirements necessary to implement ‘Extended Projected Profile’ (EPP). This RMT may also consider providing the requirements for various other applications related to the extended data link operations.

This RMT also addresses as a separate topic in the domain of ‘Air Operations’ (Regulation (EU) No 965/2012, the ‘Air OPS Regulation’), the implementation of performance-based communication and surveillance (PBCS) to support North Atlantic operations.
