SWIM enables ATM information to be exchanged between authorised stakeholders via interoperable services. It allows seamless information access and interchange between providers and users of ATM information and services. Taking advantage of service-oriented architecture (SOA) and open standards, SWIM supports operational improvements that depend on information exchanges to enable a better situational awareness and collaborative decision making.

This solution focuses on advisory information shared between airspace users and ground service providers including meteorological and aeronautical information. It aims to validate the SWIM air/ground infrastructure necessary to support ATM operational improvements based on non-safety–critical services. Air traffic control and flight crews benefit from more informed decision making as a result of this bi-directional near real-time information exchange. This SWIM application requires a set of aircraft and ground capabilities including a set of interface standards, together with infrastructure architecture and configuration aspects. As it is used for high latency, low bandwidth operations rather than real-time applications, it meets SWIM technical infrastructure purple profile criteria.

SESAR tested the capabilities and robustness of the air/ground SWIM interface, performance when multiple SWIM nodes are in use, and several aircraft communicating simultaneously. The research also considered security aspects such as authentication, authorisation and monitoring capabilities. Technical validations were used to assess target specification for elements such as data link modes, use cases and security controls, and metrics applied to evaluate reliability, time behaviour and message integrity. SESAR also carried out a high-level comparison between the SESAR air/ground SWIM solution and the US Federal Aviation Administration (FAA) Aircraft Access to SWIM development.

The results were validated in several exercises and enabled development of architectural description and specification covering functional, non-functional and interface requirements for SWIM technical infrastructure purple profile air/ground applications. Based on the analysis of the results and the conclusions, recommendations were also made for next maturity phase, regulation and standardisation initiatives.

The solution is available for industrialisation.
