System Wide Information Management (SWIM)

The concept of ‘System Wide Information Management’ - SWIM - covers a complete change in paradigm of how information is managed along its full lifecycle, involving stakeholders from across the whole European ATM network.

SWIM is SESAR's most important enabler for assuring that the right information will be available with the right quality to the right person at the right time. It covers all ATM information, including aeronautical, flight, aerodrome, meteorological, air traffic flow, and surveillance. SWIM consists of standards, infrastructure and governance enabling the management of ATM information and its exchange between qualified parties via interoperable services.


Safety – All stakeholders will share access to the information they need, including more reliable information about the future state of the ATM system and its environment. Greater automation of ATM will allow air traffic controllers to focus more on monitoring and contingency planning and this will also reduce data entry errors.

Cost efficiency – As the SWIM concept grows in maturity, standardisation and re-use of services between systems as well as the reduced duplication in managing the same information in multiple systems will bring down system operating costs for all ATM stakeholders.

Environmental impact – Increased predictability of air traffic movements and infrastructure usage at the airport will lead to optimised usage of resources which will have a positive impact on the environment.
