IR691 - Data collection process

COMMISSION REGULATION (EU) No 691/2010 of 29 July 2010 (IR691/2010) laying down a performance scheme for air navigation services and network functions and amending Regulation (EC) No 2096/2005 laying down common requirements for the provision of air navigation services, includes i.a. the mandatory provision of data.

The IR691 lays down the necessary measures to improve the overall performance of air navigation services and network functions for general air traffic within the ICAO EUR and AFI regions where Member States are responsible for the provision of air navigation services with a view to meeting the requirements of all airspace users.

Parallel to the IR691, the European Commission designated EUROCONTROL, through the Performance Review Commission (PRC), as the Performance Review Body (PRB) of the Single European Sky until 30 June 2015 (for details see Decision of 29.7.2010).

The IR691, Article 3 specifies that the PRB shall assist the Commission in the implementation of the performance scheme. One of the initial tasks is the collection, examination, validation and dissemination of performance-related data. In support of Article 3, Annex IV of the Regulation lists the data items that have to be provided by:

  • National Authorities
  • Air Navigation Service Providers (ANSP)
  • Airport Operators
  • Airport Coordinators
  • Air Carriers

The European Commission strongly invites the data providers to channel where possible the requested data through the appropriate EUROCONTROL databases (A copy of the advisory letter from the Commission may be provided on request).

For more than ten years the Central Office for Delay Analysis (CODA) has been collecting operational data from air carriers, airport operators, ANSPs and CFMU. Based on the advisory letter from the Commission the PRB requested CODA to assist in the data collection, examination and validation of flight-by-flight data from airport operators and air carriers.

CODA developed an IR691 data flow in parallel to the current voluntary reporting scheme. The IR691 reporting scheme through CODA is based on existing processes and procedures.


Who is invited to provide IR691 data to the European Commisson through CODA?

Airport operators providing services at Community airports with more than 150 000 commercial air transport movements per year and to all coordinated and facilitated airports with more than 50 000 commercial air transport movements per year. In individual cases, Member States may include airports below this threshold. They shall inform the Commission thereof.

‘Airport operator’ means the ‘managing body of an airport’ as defined in Council Regulation (EEC) No 95/93 of 18 January 1993 on common rules for the allocation of slots at Community airports (OJ L 14, 22.1.1993, p. 1.)

‘Commercial air transport movements’ means the sum of take-offs and landings involving the transport of passengers, cargo or mail, for remuneration or hire, calculated as an average over the three years preceding the adoption of the performance plan, regardless of the maximum take-off mass and the number of passenger seats used;

Air carriers which operate within the European airspace more than 35 000 flights per year calculated as the average over the previous three years.

‘Air carrier’ means an air transport undertaking with a valid operating license issued by a Member State in accordance with European Union Law.


What IR691-data is CODA collecting on behalf of the European Commission?

In addition to the data already collected by the Commission through other European Union instruments and which may also be used for performance review, national authorities, air navigation service providers, airport operators, airport coordinators and air carriers shall ensure the provision to the Commission of the data referred to in Annex IV according to the requirements set out in this Annex.

The data providers shall take the necessary measures to ensure the quality, validation and timely transmission of the data, including evidence of their quality checks and validation processes, explanations to specific requests of the European Commission related to the quality of the data and, where necessary, action plans to improve data quality. The data shall be provided free of charge, in electronic form where applicable using the format specified by the Commission.

How & where

How and where can I provide IR691-data to CODA?

Using the data sets specifications for Air Carrier and Airport Operator , a .csv file or .txt file is mailed to us.


When should I send IR691-data to CODA?

The IR691 data collection starts as from 1 January 2011. Data providers are invited to provide monthly files by 14th after the end of the flight month (e.g. data for July 2011 is provided by 14th of August 2011). If this recommendation can not be achieved the data shall be provided within one month after the end of the flight month.


As the monthly IR691 data feed has been established, CODA needs to collect meta-data to enhance the understanding of the data collection.

Hereafter you will find a spreadsheet with a few questions. These include:

  • Is your data definition compatible with the IR691 definition,
  • How are time values being recorded: manual procedures or automated using sensors (calibration?),
  • Is data being collected from a third source,
  • Do you have a data validation process or clearing procedure in place, e.g. delay code validation,
  • Can additional information on cancellations be provided (e.g. time at which a flight is cancelled)

We strongly encourage you to complete the attached survey as this will enhance the integration of individual data providers files into a common European database. Please send us back the filled form by email.
