Aeronautical data and information quality

The aviation sector needs new technologies and concepts powered by high-quality data to accommodate higher traffic demands, while keeping airspace operations safe.

At the same time, establishing new standards and practices to provide aeronautical information is a complex process since the aeronautical data chain involves numerous actors and transaction points, all of which play a critical role in producing and transmitting data of appropriate quality and format to the meet the requirements of the next intended user.

At EUROCONTROL, we support our stakeholders in the implementation of several European Commission regulations with the aim to ensure the availability of optimum quality aeronautical data and aeronautical information in Europe. We take specifically account to changes applied to global (ICAO) and regional (EASA and EC) regulations, standards and recommended practices.

We actively share our technical knowhow on the broader change process in aeronautical data exchange with a wide range of users through stakeholder meetings, workshops, training courses or events dedicated to wider audience.

Relevant regulations

The following regulations and regulatory developments are important in the context of aeronautical data quality in Europe:

  • Regulation (EU) 73/2010  of 26/01/2010 Laying down requirements on the quality of aeronautical data and aeronautical information for the single European sky.
  • Regulation (EU) 1029/2014 of 29/09/2014 Amending Regulation (EU) No 73/2010 laying down requirements on the quality of aeronautical data and aeronautical information for the single European sky
  • Regulation (EC) 552/2004  of 10/03/2004 On the interoperability of the European Air Traffic Management network (the interoperability Regulation)
  • Regulation (EC) 1070/2009 of 21/10/2009 Amending Regulations (EC) No 549/2004, (EC) No 550/2004, (EC) No 551/2004 and (EC) No 552/2004 in order to improve the performance and sustainability of the European aviation system.
  • Commission Implementing Regulation (EU) 1035/2011 of  17/10/2011 Laying down common requirements for the provision of air navigation services and amending Regulations (EC) No. 482/2008 and (EU) No. 691/2010. Regulation (EU) No. 1035/2011 repeals Regulation (EC) No. 2096/2005.
  • 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.
  • EASA Opinion 02/2018 concerning Specific requirements for providers of meteorological services, aeronautical information services/aeronautical information management, and flight procedure design services; common rules for airspace structure design
Best practices

We believe the following examples of methods, processes and activities successfully implemented by our stakeholders represent best practices contributing to the implementation of ADQ.

United Kingdom CAA

The CAA’s airspace change process published in this guidance sets out how CAA gives effect to the role to approve changes to airspace design and to the law and policy which govern this role. This guidance sets out the framework for the stages of the process and activities from conception through consulting to regulatory decision. Additionally, this guidance covers implementation and subsequent review of that change.

CAP 1616 Airspace Design: Guidance on the regulatory process for changing airspace design including community engagement requirements

This CAP provides guidance for the origination, management, transmission and distribution of aeronautical data and aeronautical information published in the Integrated Aeronautical Information Package (IAIP). This CAP also specifies the applicable guidance and acceptable standards for complying with European Regulations EU No. 73/2010 & EU No. 1029/2014.

CAP 1054 Aeronautical Information Management

This CAP provides additional guidance for aerodrome operators and other data originators (including contracted activities) to support compliance with the Regulation EU 139/2014, EU 73/2010 and relevant ICAO SARPS. This guidance also complements AMC and GM to the EU 139/2014.

CAP 1732 Aerodrome Survey Guidance


Irish Aviation Authority

On March 2010 the IAA issue a Notice to Air Navigation Service Providers to advise the EU Regulation 73/2010 (ADQ) of the entry into force of the Regulation and to highlight some significant provisions.

Notice to Air Navigation Service Providers Nr. S14 from 03/03/2010


On March 2010 the IAA launch an Ordnance Survey Ireland Tender for Areas 2 & Area 3. In August 2011 the IAA launch a tender for a Web-based Aeronautical Mapping Solution.

Slovenia Control

The EUROCONTROL Specification for the Electronic Aeronautical Information Publication (eAIP), Edition 2.0, 14 February 2011 states that applicants claiming conformance to this Specification shall complete an Implementation Conformance Statement. For this purpose Slovenia Control developed a template based on the table included in Annex B of the Specification. This template is here available both in PDF and MS Excel format.

Serbia and Montenegro Air Traffic Services Agency

GAP Analysis is often considered as a starting point for the development of an ADQ Implementation Plan. SMATSA started with drafting EC 73/2010 Gap Analysis shortly after the Regulation has been adopted. The preliminary, results of the Analysis were presented to international AIS community on the ADQ Roll-out workshop, held in June 2010 in EUROCONTROL (Brussels). This report summarizes the methodology used in SMATSA’s EC 73/2010 Gap Analysis.

Federal Aviation Administration (FAA) - USA

Noteworthy good practices include:

  • establishment of an Enterprise Data Management Program to promote a common understanding of the data sets and data standardisation;
  • involving all actors in a Data Governance Board;
  • introduction of the concept of data stewardship;
  • specifications for the collection of airport critical data
  •  explanation on how to submit this data to the FAA;

Portuguese Civil Aviation Agency

Portuguese CAA published an Aeronautical Information Circular (AIC) for training of personnel of the entities covered by Commission Regulation (EU) No 73/2010 of 26 January 2010 who are responsible for tasks in the provision of aeronautical data or aeronautical information in the single European sky.

The purpose of this AIC is to clarify and define procedures to ensure compliance with the provisions of Commission Regulation (EU) No 73/2010, in terms of the training required for the personnel involved in the origination and notification of aeronautical data or aeronautical information to the AIS provider for purposes of publication in the IAIP (integrated aeronautical information package) and the VFR Manual.
