Aeronautical Data Quality Implementing Rule

EC Reg. 73/2010

Overview

European Commission Regulation (EU) No.73/2010, commonly known as ‘the ADQ IR’, lays down the requirements on the quality of aeronautical data and aeronautical information for the Single European Sky (SES). The overall objective of this Implementing Rule is to achieve aeronautical information of sufficient quality, accuracy, timeliness and granularity as a key enabler of the European Air Traffic Management Network (ATMN).

The ADQ IR entered into force on the 26th January 2010, and was subsequently appended by (EU) No.1029/2014 on the 26th September 2014 for the updating document references. The regulation has several phases of applicability commencing from the 1st July 2013 to 30th June 2017.

Aeronautical information is made available via the Integrated Aeronautical Information Package (IAIP) that includes the UK Aeronautical Information Publication (AIP), Circulars (AIC), AIP Supplements and NOTAM, all compiled from numerous and often unique sources of data. European Commission Regulation 73/2010 focuses on data originators, and the processes that are necessary to ensure consistency and quality levels throughout the aeronautical data management chain.

The SES legislation applies to all entities originating, managing, processing or transmitting aeronautical data and information, from the point of collection or origination up to the point of publication by the National Aeronautical Information Service (AIS) provider.

Under the new concept of Aeronautical Information Management (AIM), digital data will be managed and delivered, based on commonly agreed and standardised data sets, with assured levels of quality that will support new concepts in ATM such as Performance Based Navigation (PBN) and Global Navigation Satellite Systems (GNSS), as well as allowing more opportunity to develop innovative products.

Why ADQ IR is needed

Over the next 15 years it is expected that the number of commercial aircraft flying in Europe will double. These aircraft will be managed within the same or similar amount of airspace as is currently available, but with increased efficiency levels and safety standards. To support the new systems that will allow the growth of air traffic within the European Air Traffic Management Network (EATMN), aeronautical information and data needs to demonstrate levels of quality and integrity that have never been possible before.

Currently the means of providing safety critical data is based on manual processes and procedures, and often in static data formats which cannot readily be exchanged without considerable manual intervention. Whilst every effort is made to ensure data and information is accurate and made available in a timely manner, manual intervention raises the potential for human error in existing information.

ADQIR requires information and data to be structured in accordance with ISO standards for geospatial information, including the use of the Geography Mark-up Language (GML). The Aeronautical Information Exchange Model (AIXM) was developed to meet these requirements, and enables the management and distribution of data and information in a common digital form.

The ADQ IR was implemented by the European Commission to provide a means of achieving demonstrable levels of quality for aeronautical data and information. The application of AIXM enables digital data and information to be exchanged with the associated metadata that provides the ability to determine the origin, verification, validation, validity, accuracy, and integrity, at all stages from origination through to publication in the AIP and beyond.

Implementing the ADQIR will support the new concepts of operations that will enable the UK to optimise its available airspace to the levels desired, whilst increasing safety and efficiency standards by providing assured, digital, dynamic aeronautical data and information is available for current and future ATM concepts, including - 

RNAV & PRNAV - Area (precision) Navigation.

  • Navigation systems which are not dependent on ground based navigation systems, but flight management systems that are dependent on satellite navigation and accurate digital flight management data with demonstrable levels of quality.

GNSS - Global Navigation System.

  • Instrument flight procedures based on global positioning systems require quality digital data to meet higher accuracy tolerances for the landing of aircraft.

DMEAN - Dynamic Management of European Airspace Network

  • Integrated approach to flight planning, air traffic flow, airport collaborative decision making, that will allow the ATMN to cope with the demand for more capacity in a more dynamic manner. To facilitate DMEAN digital dynamic aeronautical information of increased quality is necessary.

SES/SESAR - Single European Sky/SES Research Programme

  • An initiative to reform the architecture of the European ATM. And a programme to deliver the new technologies that will enable the envisaged modernisation. Modern ATM systems will require accurate, high integrity data and information to fully exploit SES/SESAR objectives.

A-SMGCS – Surface Movement Guidance & Control System

  • System providing routing, guidance and surveillance for control of aircraft and vehicles relies on highly accurate assured aerodrome information.

SWIM - System Wide Information Management

  • A SES initiative concerning pilots, airport operations, airline operations centres, ANSP, MET, military ops, to share aeronautical information for flight trajectory planning, aerodrome ops, meteorological forecasts, air traffic flow management, surveillance data capacity and demand information on airspace users needs of services, and access to airspace.

CAA Aeronautical Information Management Policy – CAP 1054

In fulfilling its legislative obligations to the ADQIR, the Aeronautical Information Management Regulation (AIMR) section of the UK CAA has published a CAA publication ‘Aeronautical Information Management’ (CAP 1054) that includes the necessary state policy and guidance that will facilitate stakeholder compliance to the regulation. To accompany CAP 1054, the CAA has also published an Information Notice (CAA IN 2015/052) that describes the transitional arrangements and expected ADQIR stakeholder compliance dates.

UK Preferred Means of Compliance

To assist in meeting the legislative requirements of the ADQIR, Eurocontrol, the European Organisation for the Safety of Air Navigation, has developed six specifications that when applied will assume conformity to the ADQ IR has been achieved. Although not officially published in the European Journal, and therefore regarded as official Acceptable Means of Compliance (AMC), these specifications have been adopted by the CAA as the ‘UK preferred AMC’.

The Eurocontrol specifications can be found on the publications area of the Eurocontrol web-site via the following links.

European Guidance

Eurocontrol have also produced a number of supporting documents which users may find useful. UK Stakeholders should note however that CAA Aeronautical Information Management publication (CAP 1054) describes UK policy and guidance in respect of clarifying ADQ IR requirements and has overriding authority over any contradictory guidance provided in other guidance documents.
