Aeronautical Data Quality (ADQ) Implementing Rule

The European Commission adopted on 26 January 2010 the Regulation 73/2010 laying down requirements on the quality of aeronautical data and aeronautical information for the single European sky.

The overall objective of this rule is to achieve aeronautical information of sufficient quality, accuracy, timeliness and granularity as a key enabler of the European ATM Network.

In terms of scope, the aeronautical information data process chain extends from the original data sources (e.g. surveyors, procedure designers, etc.) through Aeronautical Information Services (AIS) and publication to the end users of the data for aeronautical applications.
