The European AIS Database (EAD)

Tomorrow’s AIS Provision Today

What is EAD?

EAD is the world’s largest Aeronautical Information System (AIS), a centralised reference database of quality-assured aeronautical information and, simultaneously, a fully integrated, state-of-the-art AIS solution.

Who benefits from EAD?

EAD lets aeronautical information providers – including AIS organisations from civil aviation authorities, air navigation service providers and military administrations in the European Civil Aviation Conference (ECAC) area – enter and maintain their data in a central repository.
At the same time, EAD enables data users – such as aircraft operators, private pilots and the general public – to retrieve and download AIS data from the system in real-time.

A One-Stop-Shop, Open 24 Hours, Around the World

EAD offers instant access, no matter where you are in the world, to the most up-to-date digital aeronautical information from the ECAC area, NOTAM (Notices to Airmen), Pre-flight Information Bulletins (PIBs) from around the world.

Why EAD?

EAD is a single source for your aeronautical data needs. EAD is a safer, faster, more accurate and cost-effective solution than previous non-harmonized methods of AIS data collection and delivery, and it increases the availability and accessibility of AIS information.


The European Aeronautical Information Services Database (EAD) is a single, centralised repository of aeronautical information. It enhances quality of aeronautical data by using international standards and rigorous data-checking procedures, including in-depth validation and verification. Two main types of clients use EAD: Data Providers and Data Users.

EAD Data Providers

Data providers use the database to directly maintain and distribute their own aeronautical information. They retain full control of – and intellectual property rights over – the information they input into EAD. Data providers include:

  • Aeronautical Information Services (AIS) organisations within Civil Aviation Authorities, Air Navigation Service Providers (ANSPs) and military administrations from the European Civil Aviation Conference (ECAC) area; as well as
  • designated organisations which maintain data that does not fall under the responsibility of national agencies.

EAD Data Users

Data users consult and download data or aeronautical publications, and generate reports from EAD. Typical data users include:

  • Data providers;
  • Aircraft operators;
  • International organisations;
  • Private pilots;
  • Commercial users; and
  • the general public.


The European AIS Database (EAD) offers a number of clear benefits to both Data Providers and Data Users. They include:

  • a reliable source of European aeronautical information in real-time;
  • significantly improved data quality enabled by constant data-checking (based on International Civil Aviation Organisation (ICAO) and EUROCONTROL recommendations), including NOTAMs (Notice to Airmen) validation and cross-border data-coherence verification;
  • ensure data integrity based on cyclic redundancy checks (CRC);
  • additional cross-border data-coherence verification;
  • a secure channel for timely and efficient electronic distribution of aeronautical information to all users; and
  • reduced workload throughout the complete AIS process;
  • reduced investment costs in development and maintenance of local systems by both AIS Units and airspace users;
  • increased availability of data through easy access.

The EAD contributes to a reduction in safety risks posed by the distribution and publication of aeronautical information. A full safety case, in line with EUROCONTROL ESARRs, has allowed to identify, mitigate and manage all risks with respect to the introduction, operation and correct use of the EAD.


The EAD Service Steering Group was created to provide guidance for the management of EAD. Its mission consists of steering EAD service provision, maintaining commitment from EAD stakeholders and encouraging a standardised approach for the exchange of aeronautical information and related data.

Meetings are taking place every six months and are focusing on general management, system management, client migration, system performance and operational issues.

  • Secretary: D. Dos Santos

Who takes part in the SSG

The SSG is composed of senior representatives from civil and military governmental organisations and corporate or privatised Air Navigation Service Providers (ANSP) that have a vested interest in aeronautical information (AI) and/or responsibility for the provision of AI for or on behalf of:

  • a European Civil Aviation Conference (ECAC) member state,
  • any non ECAC member state which has migrated to EAD as a data provider.

What are the SSG responsibilities?

The main tasks of the EAD SSG are to:

  • provide guidance to the Head of European Aeronautical Information Management Unit (EAIM) and ensure that the EAD evolves in line with EUROCONTROL objectives and customers’ requirements,
  • provide advice, guidance and support to the Head of EAIM related to the management of the EAD Systems and Services,
  • advise on operational, policy or financial decisions to ensure that the EAD service remains viable and meets its business objectives,
  • agree on actions for all matters having a major impact on the EAD functionality and/or on the budget before reporting these to the relevant authority,
  • perform an annual review of the EAD service and copyright charging scheme.
