State Joint Stock Company “Latvijas gaisa satiksme” (LGS) has been working on introducing the services envisioned by the System Wide Information Management (SWIM) initiative since 2023, and by the end of 2025 aeronautical information exchange services will be placed into operational use.

The SWIM aeronautical information exchange services are being introduced in the framework of the CLEAN ATM (CP1 Deployment – Synchronised Modernisation of ATM) project, under the section Acceleration of Aeronautical Digital Information Availability (ACADIA). The implementation of ACADIA is being coordinated by the European Organisation for the Safety of Air Navigation (EUROCONTROL) with more than 20 partners from 17 countries involved in the project.

The aim for the introduction of SWIM is to digitise information exchange throughout the European air traffic management system ensuring delivery and exchange of quality assured information between aeronautical information service providers, air traffic control services and airports regardless of their geographic location, civilian or military nature, their role in the provision of air navigation services, the systems they use or the manufacturers thereof.

Users will be provided with Aeronautical Information Feature Service allowing them to receive aeronautical information features on request via query-based interface and filtering elements by type, name, spatial, time or logic parameters. Furthermore, the digital NOTAM service will ensure digitally coded NOTAM data displaying events which temporarily impact the air navigation.

“This is one of the most important European air traffic management modernisation projects that we are a part of. By gradually moving forward with technological upgrades and procedural improvements, LGS is contributing to increased efficiency and safety of air traffic,” Dāvids Tauriņš, Chair of the Board at LGS, explains.

Real-time sharing of aeronautical data and information will promote flight efficiency as the information received will help optimise flight trajectories, thus indirectly also impacting air space capacity and flight execution, it will also help reduce fuel consumption and environmental impact.

Further information and technical documentation about service endpoints (access points), service interface specifications and user guidelines is available on the Eurocontrol SWIM service registry website https://eur-registry.swim.aero/services (search by service provider name: LGS) as of 11 July 2025 and will be updated as necessary. All interested users are welcome to provide their feedback by emailing ais@lgs.lv.

The CLEAN ATM project is co-financed by the Connecting Europe Facility (CEF), and according to the agreement with the European Climate, Infrastructure and Environmental Executive Agency, the ACADIA section of the CLEAN ATM project is to be completed by 31 December 2025.

To support these efforts, we would highly appreciate your feedback on the quality of services provided by LGS.

The questionnaire takes approximately 3 minutes to complete. All responses will be treated confidentially and will not be associated with your name.
