The EASCG is a joint coordination and advisory group established to coordinate the ATM-related standardisation activities, essentially stemming from the European ATM Master Plan, in support of Single European Sky implementation.
The membership of the EASCG includes:

The European Commission took the initiative in July 2014 to bring together the various organisations developing ATM related standards and specifications with the objective to clarify, streamline and eventually coordinate the European ATM standardisation activities. This initiative resulted in the establishment of the EASCG which held its first meeting in January 2015.
As originator and promoter of the EASCG, the European Commission is a plenary member of the EASCG, and is financially supporting the work of the EASCG through a grant to EUROCAE, which provides EASCG’s secretariat.

The European Union Aviation Safety Agency (EASA) is the centrepiece of the European Union’s strategy for aviation. EASA regularly revises the risks and improves the common regulations applied among EU countries so they are always of the highest standard. EASA works hand in hand with the National Aviation Authorities and aviation industry across Europe to achieve these goals.
EASA is a plenary member of the EASCG and provides the Chair for the group.

EUROCAE currently has around 500 members, including industry, service providers, regulators, research institutes and international organisations. EUROCAE membership is open to organisations and industries worldwide. EUROCAE, in the interest of its stakeholders, develops technical specifications for the aviation industry and in support of regulations, aiming to increase safety, market potential, facilitate interoperability and encourage technological development.
EUROCAE is a plenary member of the EASCG and provides the Secretariat to the group.

CEN (European Committee for Standardization) and CENELEC (European Committee for Electrotechnical Standardization) are recognized by the European Union (EU) and the European Free Trade Association (EFTA) as European Standardization Organizations responsible for developing standards in relation to a wide range of materials, processes, products and services.
The CEN/TC 377 “Air Traffic Management” has developed standards in the area of Information security and software assurance levels. CEN-CENELEC is a plenary member of the EASCG.

ETSI is one of the world’s leading standards development organisations for Information and Communication Technologies (ICT) and is a plenary member of the EASCG.
In the aeronautical sector, ETSI is involved in the production of European Norms in support of the Single European Sky as well as Harmonised Standards for ground ATM equipment, meteorological radars, aeronautical satellite services, direct air-to-ground communication, communication on board aircraft and much more. As such ETSI provides valuable contribution to the European ATM standardisation rolling development plan as defined by EASCG as well as to the CP1 roadmap as defined in Commission Implementing Regulation (EU) 2021/116.

EUROCONTROL is an intergovernmental organisation of 41 Member States, committed to building, together with its partners, the European Union’s vision for a Single European Sky. EUROCONTROL supports its Member States and stakeholders (including air navigation service providers, civil and military airspace users, airports and aircraft/equipment manufacturers) in a joint effort to make aviation in Europe safer, more efficient, more cost-effective and with a minimal environmental impact.
EUROCONTROL, as an organisation involved in the planning and development of ATM-related standards, is a plenary member of the EASCG.

The SESAR Joint Undertaking (SESAR JU) is an institutionalised European partnership between private and public sector partners set up to accelerate through research and innovation the delivery of the Digital European Sky.
The SESAR JU is a plenary member of the EASCG and is responsible for the European Air Traffic Management (ATM) Master Plan, the roadmap for delivering the Digital European Sky and making Europe the most efficient and environmentally friendly sky to fly in the world by 2045. The Master Plan provides the strategic framework for development and deployment (including standardisation) activities, ensuring that all phases of the SESAR lifecycle remain connected.
The following organisations are invited to participate as observers:

ASD is the voice of European Aerospace, Security and Defence Industries. With 25 major European companies and 25 National Associations as our members, the overall representation adds up to more than 4,000 companies across 21 European countries. We are actively supporting the competitive development of the sector in Europe and worldwide. Their members collectively employed 921,000 people and generated a turnover of €261 billion in 2022.

CANSO – the Civil Air Navigation Services Organisation – is the global voice of air traffic management (ATM) worldwide. CANSO Members support over 90% of world air traffic. Members share information and develop new policies, with the ultimate aim of improving air navigation services (ANS) on the ground and in the air. CANSO represents the views of its Members to a wide range of aviation stakeholders, including the International Civil Aviation Organization, where it has official Observer status. CANSO has an extensive network of Associate Members drawn from across the aviation industry.

With more than 11,000 aircraft currently stationed in Europe, the military are Europe’s biggest airline. Europe’s armed forces operate more than 150,000 flights per year. The Single European Sky initiative and its technological pillar, the Single European Sky Air Traffic Management Research (SESAR) programme, thus have considerable implications for the military. The European Defence Agency was originally given responsibility at its Steering Board in November 2010 to evaluate the operational risks and financial implications of the Single European Sky for military aviation. This role was further extended in May 2013 with the adoption of an implementing regulation that set the ground for EDA work at the policy level of SESAR.

The SESAR Deployment Manager (SDM) was created in 2014 by the European Commission and operational stakeholders in European aviation, i.e., airlines, airports, and air navigation service providers. SDM is tasked with planning, coordinating, and synchronizing the implementation of new ATM functionalities mandated by the EU. These functionalities are based on innovative technical and operational solutions resulting from the R&D phase of the SESAR project.
SDM holds observer status in EASCG. Given their respective roles, SDM can be considered a “customer” of EASCG. In this role, SDM regularly reports to EASCG on the supporting material required to enable timely implementation while ensuring safety and interoperability.
