SESAR is paving the way for the seamless information data access and exchange in air traffic management between all stakeholders, thanks to its work on system-wide information exchange (SWIM).  The first SESAR JU programme (2008-2016) saw the delivery of the technological solution with several key elements, including: an aeronautical information reference model (AIRM) to ensure semantic interoperability;  an information service reference model (ISRM) to ensure organisational interoperability; SWIM technical infrastructure (SWIM TI) profiles and architecture to enable technical interoperability; and a SWIM registry to improve the visibility and accessibility of ATM information and services available through SWIM.

These elements are now enabling the development and Europe-wide deployment of initial SWIM services targeting data exchange between various stakeholders in the ATM ecosystem through pre-existing data transfer networks, such as NewPENS (“digital backbone”). A good example is the business-to-business service which SESAR founding member, Eurocontrol, has put in place to support the network operations plan (NOP) of the European Network Manager (NM). The NOP provides a means for all actors, civil and military, to increase their respective knowledge of the situation from the strategic phase to real-time operations.
