1. The European Organisation for the Safety of Air Navigation Introducing the DQR Concept DAL/DQR Workshop Brussels, 19-20 February 2013 Presented by: Miguel Rodrigues Paulo SES unit EUROCONTROL

2. 2 Specification Scope The scope of the DQR Specification is to address Article 6(1) – Data Quality Requirements - of the Commission Regulation (EU) No 73/2010 and the requirements in Annex IV, Part A. The DQR Specification is built on the assumption that ICAO requirements for accuracy, resolution and integrity are considered to provide a sufficient baseline for current aeronautical data and aeronautical information data quality requirements However, it is also recognised that there are known deficiencies that should be addressed, notably to support future operations, and the DQR Specification establish a standard methodology to derive new or updated data quality requirements

4. 4 Regulation Provisions (1) Article 6(1) Member States shall ensure that air navigation service providers comply with the data quality requirements laid down in Annex IV, Part A. Annex IV, Part A ICAO Standards as the baseline for data quality requirements If the data item is not defined in the ICAO standards or if the ICAO data quality standards do not met the data quality requirements for a specific data item, new data quality requirements may be established New or updated data quality requirements shall be established based on a safety assessment of the intended use of the data item and in accordance with a standardised process.

5. 5 Regulation Provisions (2) Annex IV, Part A (cont.) Data quality requirements: accuracy and resolution integrity level ability to determine the origin of the data level of assurance that the data is made available on time

6. 6 Underlying Principles(1) The DQR introduces the Data Quality Requirements Harmonised List (DQR HL) Edition 1.0 of the DQR HL is published with an initial set of geospatial and other navigation data items, limited to those included in Appendix 7 of ICAO Annex 15 Integrity and resolution data quality requirements are transposed literally from ICAO Annex 15 Accuracy data quality requirements are transposed literally from ICAO Annex 11 and ICAO Annex 14
