The report identifies incompatibilities between airborne and ground systems, probably caused by inconsistencies in the interpretation of standards but also lack of standardisation of important system elements. The SESAR Joint Undertaking (SJU) investigated performance issues afflicting data link services used in support of Air Traffic Management (ATM) and produced the report “Enhanced Large Scale ATN deployment (ELSA)". Hence, implementation of alternative air-ground communication technologies must be accelerated for operations in mid-2020s. The modernisation of the European Air Traffic management is dependent on data link based services. Timely implementation of the envisaged new services, particularly Trajectory Based Operations, is being jeopardised by lack of performant data link between aircraft and ground Air Traffic Management systems. ETSI EN 303 214 “Data Link Services (DLS) System Community Specification for application under the Single European Sky Interoperability Regulation EC 552/2004 requirements for ground constituents and system testing" is the standard supporting data link services.Įfficient data link services are fundamental cornerstones of the Single European Sky Operational Concept that is to be developed and implemented through the European ATM Master Plan. This Regulation was repealed but the interoperability requirements are still valid and will be transposed in the next revision of the Commission Implementing Regulation 2017/373.Ĭommission Regulation (EC) No 29/2009 as amended by Commission Implementing Regulation (EU) 2015/310 lays down requirements on data link services for the Single European Sky. The Single European Sky (SES) Interoperability Regulation EC 552/2004 has been one of the pillars of SES and sets out requirements for constituents and testing of ground-based ATM systems. These need to be revised in order to align to the future rules on conformity assessment as provided in Article 140 of the New Basic Regulation. Community Specifications) and of EC Declarations is provided.Ī number of Implementing Regulations have been adopted which refer to the former Interoperability Regulation (EC) No 552/2004, some of which refer to harmonised standards or Community Specifications. During the transition period until September 2023, grandfathering of existing standards (i.e. These future rules for demonstrating compliance with relevant requirements for safety, performance and interoperability aim to ensure the proper functioning of European ATM operations (Rule Making Task RMT.0161). In line with the European Plan for Aviation Safety (EPAS) 2020-2024 the European Aviation Safety Agency (EASA) will develop a new framework on conformity assessment of ground systems and constituents used in the provision of ATM/ANS. During a transition period, ending on 12 September 2023 the requirements on developing standards and assessing the conformity remain valid. With the adoption of the New Basic Regulation the Interoperability Regulation was repealed and the essential requirements for air traffic management systems have been transferred to this new Regulation. Achievements have already been made at operational, technological and institutional levels and efforts are ongoing to maximise the benefits of activities initiated under the SES framework.Īs a key pillar of the Single European Sky (SES) Regulation (EC) No 552/2004 on the interoperability of the European Air Traffic Management has set out requirements for developing standards and for testing of ground-based ATM systems and constituents. This implies (re-)designing the European airspace to support air traffic flows in alignment with technological capabilities and operational functionalities, reducing delays, increasing safety standards and flight efficiency to reduce the aviation environmental footprint, and reducing costs related to service provision. The EU’s Single European Sky (SES) initiative has at its heart the reform of the Air Traffic Management (ATM) in Europe in order to cope with sustained air traffic growth and operations under the safest, most cost- and flight-efficient and environmentally friendly conditions.
