European AIS Database

The single source of aeronautical information
serving ATM and beyond

The European Aeronautical Information Services Database (EAD) is a centralised reference database of quality-assured aeronautical information that enables users to retrieve and download AIS data in real time. 

It provides instant access to the most up-to-date digital aeronautical information from the ECAC and ECAC+ areas, from Notices to Airmen (NOTAMs), pre-flight information bulletins (PIBs), briefing facility services and the AIP library.

EAD is the world’s largest aeronautical information management (AIM) system.

Ead offers
  • a reliable and cost-effective integrated AIS solution that meets user needs;
  • access to real-time data of guaranteed integrity and quality;
  • consistency with ICAO and EUROCONTROL standards and recommendations;
  • a secure channel for a timely electronic distribution of aeronautical information;
  • support to clients during their transition to EAD;
  • service availability 24h per day, 7 days per week.

EAD is safer, faster, more accurate and more cost-effective than older, non-harmonised methods of AIS data collection and delivery. It increases the availability and accessibility of AIS information, and it contributes to reducing safety risks related to the distribution and publication of aeronautical information.

On 9 December 2016, EUROCONTROL became the first pan-European aeronautical information service provider to be certified under the Single European Sky legislation regarding the provision of the European AIS Database (EAD).

Client types

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.

EAD data providers include:

  • aeronautical information services (AIS) organisations within civil aviation authorities, air navigation service providers (ANSPs), and military administrations;
  • designated organisations which maintain data that does not fall under the responsibility of national agencies.

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

Typical data users include:

  • Aeronautical information services (AIS), civil aviation authorities, air navigation service providers (ANSPs), military administrations, airports, etc.;
  • Aircraft operators;
  • International organisations;
  • Private pilots;
  • Commercial users; and
  • The general public.


The data sourced globally includes original and processed NOTAM, SNOWTAM and ASHTAM messages, as well as minimum sets of static data operation (SDO) required for NOTAM validation and pre-flight information bulletin (PIB) generation, including aerodromes identification with associated runways, airspaces (FIR, UIR, TMA, P-D-R pre-determined routes), routes, navaids and waypoints.

Data from ECAC States and beyond includes original and processed NOTAM, SNOWTAM and ASHTAM, AIPs, AICs, amendments, supplements, charts, as well as full set of aeronautical information data published in AIP. It also covers aerodrome information including procedures, obstacles, en-route information such as airspace, routes, navaids and waypoints, and general information such as organisation, authority and units.

Worldwide EAD users

EAD has been providing AIS services for over 15 years. As of January 2019, 49 States had aligned themselves with the EAD processes and systems in their aeronautical information management solutions. Four additional States are in the process of migrating to the EAD and 12 other States have expressed an interest in adopting the service.

EAD data providers include European States, but also countries such as Canada, the Philippines and South-Africa. In January 2019, EAD had some 200 EAD data users worldwide.


As a central repository of aeronautical information, the EAD offers a number of integrated sub-systems that support the daily operations of AIS units.

These sub-systems can be used in any combination, in function of each client’s needs and preferences.

They enable aeronautical information users to retrieve the information they need through their respective functions: retrieval or querying of static data (SDO), download  of AIP information (PAMS),  or  PIB and NOTAM retrieval (INO). ATS reporting offices can also use the INO briefing facility (BF) to manage and distribute their flight plans.

The core components of the EAD are the following:


Static data operations


AIP and chart production tools


Published AIP management system


International NOTAM operations


ARO briefing facility


Workflow management tool

Access EAD Pro

Clients are provided with all the necessary technical documentation and software once the EAD Agreement has been signed.

EAD Basic

In addition to this, we offer EAD Basic, our free public access service application for the general public, which makes it possible to browse the European AIS Database (EAD) for a limited set of aeronautical information. EAD Basic is free of charge and can be accessed online instantly, anytime and from anywhere.

The information accessible via EAD Basic is for general purposes only. For safety and security reasons, the data shall not be used for operational purposes.

Access EAD Basic

Data download

It enables the user to retrieve a dedicated data set at intervals (e.g. AIRAC cycle) from the EAD that can then be manually inserted/loaded into a local system. This is the solution if a continuous connection with the database is not required and only updates are needed when there are data changes. Data files are made available through the EAD Internet Filing System (EAD IFS).


If needed, NOTAM information contained in the EAD can also be made available through a regular AFTN connection.


Applicable charges vary per EAD client type. They may include service charges, applied by EURCONTROL, as well as royalty fees, applied by the Member States, in cases where EAD data is made available by the client to third party end users.

The table below shows the applicable charges per client type:

  Service Charges Royalty Fees
Type 1
Clients that are acting on behalf of a EUROCONTROL Member State;
Clients that are recognised airspace users paying en-route charges.
No No
Type 2
Clients using the data for their own operational business without reselling and/or commercialising it, but which do not contribute to EUROCONTROL budget or are not recognised airspace users.
Yes No
Type 3
Clients that intend to commercialise the data with or without value added products and make data available to third party end-users.
Yes Yes

The level of charges applied for the use of EAD data is based on how and where the data will be used, as well as the related turnover (in €/year) of the product or service that makes use of EAD data. This method ensures that all users pay charges commensurate with the size of their business.

In case no turnover is available yet (start-up), a flat fee per year is applied.

The amount of charges will be determined during the agreement discussion between the EAD service and the client. Clients will be asked to produce the related turnover evidence.

In addition, each EAD data user should have an adequate liability insurance coverage, the level of which depends of the usage of the EAD data.

Please see Annex 5 Attachment B of the Template of the EAD Agreement.

When the EAD data user chooses to access the EAD services through the ready-to-run EAD Pro software package, a yearly software license applies. The price list is available here.

When the EAD data user chooses to access through MyEAD (B2B web services based called AIMSL – AIM Service Layer), or through manual data download in case of SDO static data, no additional charges apply.


EAD will issue annual invoices to the EAD client. Payment shall be made by the client, within a period thirty calendar days of the date of the invoice within the bank account number as indicated in the invoice.

Each invoice will be issued in the standard EUROCONTROL format. Each invoice will be signed and stamped. The original invoice will be sent by regular post to clients. Upon the client’s request, a scanned (PDF) version of the invoice can be sent by mail.

Fraud warning for EAD Clients

If you receive dubious e-mails or calls, please contact the EAD service immediately via our contacts.

What information can you trust?

We post you official EUROCONTROL documents, such as bills and statements of accounts, all printed on secured watermarked paper, bearing the EUROCONTROL logo.

We provide support and training for EAD clients - data providers and users - during the migration process, as well as during operational activities, as follows:

Classroom courses by Group EAD

The correct and efficient use of the EAD requires detailed knowledge of the EAD applications provided. We offer training for EAD users through GroupEAD. For information on our training offering, please visit the EAD Training Catalogue. Taught by experts with extensive hands-on experience in using the EAD systems, the courses take place in a variety of locations.

Classroom courses by the EUROCONTROL Institute of Air Navigation Services in Luxembourg

EUROCONTROL's Institute provides three Information Management courses. The course contents can be consulted in the Airspace Management section of the IANS Training Catalogue.

The EAD Service Desk is a service available 24 hours a day, 7 days a week to EAD Migrated clients' (Data Providers & Data Users) to address technical and operational enquiries.

The Knowledge Base is based on experiences gained by all EAD users. It is available to Data Providers and Data Users as a primary source of information and support.

The Knowledge Base tool offers multiple knowledge models to access all kinds of information. As a consequence, different users might see different results when searching in the Knowledge Base.

It enables rapid knowledge-based searches to quickly resolve client's issues and can be accessed by means of the Helpdesk button on the EAD Explorer button bar.

Users can search for a solution in the database by typing in keywords in the search field provided or they can browse among the Top Solutions and find an answer to their request.

A list of relevant documents according to the search criteria or keywords will then be displayed in the main panel.

Alternatively, documents can be browsed by subsystem (SDO, INO, PAMS, Charting, etc.)

SIGMA (SDO Input Guidance Manual) is a web based support tool for EAD SDO Data Operators.  It provides a single point of access for SDO Operators for data maintenance support guidelines. It was introduced in 2009 and bridges the AIS and AIXM (SDO) world of understanding.

SIGMA is available to both MyEAD and EAD Pro users.  

SIGMA offers up to date SDO input guidance support through:

  • Single-source access for Operational SDO Data Management aspects
  • "Single point of entry" for access to  SDO relevant operational content
  • Diverse views of the European AIS Database (EAD) AIP, Data Harmonisation, Operational rules and SDO perspective views

EAD Data Providers are obliged to maintain their static data after migration to the EAD.

Digital Aeronautical data is a key enabler for automated flight support systems in ATM. In order to fulfill operational requirements, a pre-requisite is the availability and quality of aeronautical data.

Due to the high number and the complexity of requested data, the existing static data consistency review process has been enhanced with SDO data completeness procedures and a specific Data Completeness and Annotation tool (SDC Tool).

In addition, the SDC Tool is used for Data Annotation to support the transition for compliance with European Commission Regulation (EU) 73/2010 and with EASA certification requirements.

Data Completeness

As part of the quality requirements, a Data Completeness process has been set up to facilitate the monitoring of static data. This is enabled through the SDC tool and data provider procedures, as described in the EAD SDO Data Completeness Guidelines. SDC Data is based on a two monthly AIRAC cycle (56 days) replication of the SDO production Data. The Data Provider can use SDC to monitor and identify missing data and provide NIL reasons during this two-monthly time frame indicating the status of completeness.


  • The EAD SDO static data set is described in the EAD Data Catalogue which is based on ICAO Annex 15.
  • The EAD has implemented a specific solution, based on the SDC Tool, to facilitate the annotation of non-compliant data items.
  • The SDC allows ADQ Annotations and DQR Annotations. The EAD publishes for each Data Provider a resulting Annotation Report. This allows EAD clients to be informed about the ADQ & DQR Annotation Status of each Data Item provided by the EAD.
  • The ADQ and DQR Annotations are updated every double AIRAC and EAD clients are informed in advance of the SDC update.
  • The publication of Annotation reports can be accessed by EAD clients through the EAD Knowledge Base by going to ADQ - Annotation reports.
  • For data maintenance support guidelines, consult the SIGMA – SDO Input Guidance Manual

Data model


AIXM is the backbone of EAD and represents both the data model on which the static data (SDO) is based, as well as the exchange means for the aeronautical data.

EAD supports AIXM 4.5 in uploading and downloading aeronautical data in SDO and since Release 10, also the upload and download in AIXM 5.1 format.

AIXM 5.1 is the version of the data model and exchange schema implemented in EAD which complies with the European Commission (EU) Regulation 73/2010), with the ICAO SARPS provisions for electronic obstacle data (part of eTOD) and with the Digital NOTAM.

To date, EAD supports BASELINE data exchange for uploading aeronautical data and BASELINE and / or PERMDELTA for downloads in AIXM 5.1 format.

The specifications on which the implementation of AIXM 5.1 in EAD is based, are listed below:

  • AIXM 5.1 Temporality Concept (EAD has developed a more detailed AIXM 5.1 Temporality Implementation specification which is included in the SDD XML Primer (available for EAD Clients))
  • AIXM 5.1 Feature Identification and Reference
  • AIXM 5.1 Business Rules (the rules identified in the EAD Profile)
  • AIXM 5.1 Application Schema and Extensions (for AIXM 5.1 extensions)
  • OGC Use of GML for Aviation Data (ref. OGC 12-028r1 – the GML Profile provided in this specification is implemented in EAD since EAD Release 11)

These specifications and other AIXM 5.1 reference documentation are published on www.aixm.aero.

Certification and data quality

EUROCONTROL has been certified by the European Aviation Safety Agency (“EASA”), since 9 December 2016, as an Air Navigation Service Provider (“ANSP”) for the provision of Aeronautical Information Services (“AIS”). The AIS provided by EUROCONTROL are based on the European Aeronautical Database (“EAD”). As from 02 January 2020, the regulatory framework of EAD changed as the previous Implementing Regulations (EU) No 1034/2011 and (EU) No 1035/2011 were repealed by Commission Implementing Regulation (EU) 2017/373 [1]

It is important to note that aeronautical information transferred to and stored in EAD Static Data Operations (“SDO”) database do not comply with the requirements of the Commission Regulation EU 73/2010 [2] on aeronautical data quality. This is due to the fact that EAD has not received the full compliance statement regarding data quality or the required mandatory data quality attributes from all States and, as a consequence, cannot claim full Data Quality Review (“DQR”) compliance for States within the scope of this regulation.

However, since EAD is applying the Commission Regulation (EU) 73/2010, the level of compliance for the States within the scope of this regulation is monitored by EAD and accessible from the EAD website at the following link.

Further, according to the same Regulation (EU) 73/2010, “Member States shall ensure that air navigation service providers comply with the data quality requirements laid down in Annex IV, Part A” (Art 6,a) and that “Aeronautical information service providers shall ensure that aeronautical data and aeronautical information items published in the AIP of their Member State are annotated to indicate those that do not meet the data quality requirements laid down in this Regulation”.

In this context, EUROCONTROL cooperates actively with the States within the scope of the Regulation, with a view to assist them in improving data quality and publishes their annotation reports showing their DQR compliance per data item.

  • [1]Commission Implementing Regulation (EU) 2017/373 of 1 March 2017 laying down common requirements for providers of air traffic management/air navigation services and other air traffic management network functions and their oversight, repealing Regulation (EC) No 482/2008, Implementing Regulations (EU) No 1034/2011, (EU) No 1035/2011 and (EU) 2016/1377 and amending Regulation (EU) No 677/2011
  • [2] COMMISSION REGULATION (EU) No 73/2010 of 26 January 2010 laying down requirements on the quality of aeronautical data and aeronautical information for the single European sky

Governance and evolution

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

Meetings take place every six months and focus on general management, system management, client migration, system performance and operational issues.

  • Chairman: Maja Martek Socec
  • Secretary: Alex Petrosvky

SSG members

The SSG is composed of senior representatives from civil and military governmental organisations and air navigation service providers, which 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.

SSG responsibilities

The main tasks of the EAD SSG are to:

  • provide guidance to the Head of European Aeronautical Information Management Unit (EAIM) and to ensure that the EAD evolves in line with EUROCONTROL’s objectives and customers’ requirements;
  • provide advice, guidance and support to the Head of EAIM on 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 with a potential major impact on the EAD functionality and/or budget before reporting on these to the relevant authority;
  • carry out an annual review of the EAD service and its copyright charging scheme.

eEAD and eAIMS

The enhanced European AIS Database (eEAD) is the first step towards the realisation of the target EAIMS project. The new eEAD will ensure at a minimum the continuation of all services and functions of the current EAD system. The procurement of an eEAD system to replace the current AIS database is done through an open call for tenders (CFT).


This eEAD Concept of Operations (CONOPS) document (edition 6.0) describes the overall operational concept of eEAD and in particular the services it provides. It will be used as a reference for the future eEAD procurement.

This document takes into consideration all requirements that stakeholder have of the current EAD services and systems. The CONOPS has passed through several workshops and successive consultation rounds with all actors of the aviation business, including ANSPs of EUROCONTROL member States, airspace users, major data houses and the aircraft operations industry.

This CONOPS 6.0 was endorsed unanimously by the EAD Service Steering Group members at their 27th  meeting. The document represents the official scope of the eEAD project. The document is available for download below. For any questions on this matter, please contact the eEAD Project Manager.


The European ATM Information Management Service (EAIMS) is a Network Manager Strategic Project (part of the Network Strategy Plan). The project is in line with activities taking place under the SESAR Deployment Programme and the (Pilot) Common Projects. The goal of EAIMS is to ensure access to consolidated, consistent and NM operationally validated data in a seamless and transparent way from a single access point in support of ARO/AIS/ASM/ATFCM/ATS, flight operations and airport operations.
