The modernisation of the European Air Traffic Management (ATM) network is based on System Wide Information Management (SWIM) enabling interoperable information exchange. The ATM Information Reference Model (AIRM) is referred to in the context of European initial SWIM standardisation (iSWIM).

ATM related information is exchanged using information services between service providers and service consumers. For semantic interoperability reasons, the information needs to be clearly and uniquely defined, well understood and its meaning preserved as it travels through the European ATM network. This is where the AIRM plays a key role as a unifying SWIM standard.
