How does CHAIN relate to the EU Aeronautical Data Integrity (ADI) Mandate?
Whilst in some ways they may be considered separate activities, it would not be sensible for these two tasks to be completely executed in isolation. It should be ensured that a common approach and compatible recommendations are being made. The CHAIN Activity and the EUROCONTROL Regulatory Unit are in close communications and both parties support the other in their tasks. They are wholly compatible although, to an extent, their objectives are slightly different: o CHAIN is providing guidance and advice on the implementation of integrity processes, supporting States in a voluntary approach; o The ADI Mandate is focussing on implementing rules for integrity. It could be argued that the latter only says what has to be done with CHAIN providing the guidance on how it can be done.
