From Guidance to Implementation: CANSO and CAAS share practical lessons on SWIM

CANSO has contributed to the International Civil Aviation Organization’s (ICAO) video series, SWIM in Practice: From Guidance to Implementation, highlighting how air navigation service providers (ANSPs) can turn System Wide Information Management (SWIM) principles into practical operational capabilities.

As aviation continues its digital transformation, the ability to exchange information seamlessly, securely and efficiently across systems, organisations and borders is becoming vital.

SWIM is a fundamental enabler of this transformation, providing the foundation for a more connected, collaborative and interoperable global air traffic management (ATM) system.

However, while the benefits of SWIM are widely recognised, one important question remains for many ANSPs: How do we move from understanding SWIM to implementing it?

Through its contribution to ICAO’s video series, CANSO seeks to help answer that question by combining practical implementation guidance with real-world operational experience from the Civil Aviation Authority of Singapore (CAAS).

Making SWIM Implementation More Accessible

The video begins by introducing the CANSO SWIM Implementation Kit, developed in collaboration with ANSPs and industry partners to support organisations taking their first steps towards SWIM implementation.

Designed to complement ICAO’s existing provisions and guidance, the Kit provides practical tools, implementation considerations and lessons learned to help ANSPs translate SWIM concepts into operational capabilities.

Rather than viewing SWIM implementation as a complex, all-or-nothing technological undertaking, the Kit encourages organisations to adopt a progressive approach: start with a clearly defined operational need, establish an initial use case, build experience and expand capabilities over time.

The Kit includes a hands on SWIM tool that enables organisations to experiment with a minimal implementation, alongside practical checklists, procurement considerations and guidance informed by existing ANSP implementations.

The underlying message is simple: Start small, learn by doing and build progressively.

By making implementation more accessible, CANSO aims to support ANSPs at different stages of digital maturity, recognising that there is no single approach suitable for every operational environment.

Learning from Singapore’s SWIM Journey

To demonstrate how these principles can be applied in practice, the video features David Leow, Head of Quality Assurance, and Elvin Liow, Head of Open Platform for Air Navigation Services, from CAAS, who share Singapore’s experience implementing SWIM over more than a decade.

Singapore’s journey began in 2013 with participation in the FAA-led Mini Global demonstration, which introduced concepts such as service-oriented architecture, standardised data models and SWIM information services.

Further demonstrations in 2016 helped explore more advanced use cases and provided a clearer understanding of SWIM’s potential operational benefits.

CAAS subsequently developed a prototype SWIM environment, initially using surveillance information from systems such as ADS-B and Advanced Surface Movement Guidance and Control Systems (A-SMGCS). This early implementation provided valuable experience in exchanging operational information between systems and applications.

A significant milestone followed in 2019, when CAAS participated in the Association of Southeast Asian Nations (ASEAN) SWIM Demonstration. This regional initiative explored information-sharing use cases relevant to Asia-Pacific operations and helped inform the development of regional SWIM architecture and implementation approaches.

Building on these experiences, CAAS progressively enhanced its infrastructure to support ATM operations, introducing centralised messaging capabilities, a web-based SWIM registry and connectivity through Common aeRonautical Virtual Private Network (CRV) and Internet gateways.

The journey illustrates how early experimentation, regional collaboration and incremental investment can provide a foundation for increasingly advanced SWIM capabilities.

Beyond the technology itself, the CAAS experience highlights several important considerations for organisations planning their own SWIM implementation.

One of the most invaluable lessons is the importance of establishing clear operational requirements before selecting architecture. Decisions about information exchange, system connectivity and future expansion should be driven by operational needs rather than technology alone.

CAAS also emphasises the need for effective governance, including organisational SWIM policies, clear procedures for onboarding new information services, maintenance planning and processes for retiring outdated applications.

Equally important is understanding the distinction between SWIM infrastructure and the applications and information services that use it.

These considerations reinforce that successful SWIM implementation is not simply about introducing new technology. It also requires organisational readiness, coordination between stakeholders and a long-term approach to managing information services.

For ANSPs beginning their journey, learning from organisations that have already navigated these decisions can help reduce uncertainty and support more informed implementation choices.

Looking ahead, SWIM will play an important role in enabling the next generation of ATM capabilities.  In Singapore, CAAS is continuing to develop its SWIM infrastructure, with plans for enhanced availability, cloud-based capabilities and support for future operational concepts.

These developments are closely connected to regional priorities, including multi-nodal Air Traffic Flow Management (ATFM), Flight and Flow Information for a Collaborative Environment (FF-ICE) and the longer-term transition towards Trajectory-Based Operations (TBO).

With the Asia-Pacific region targeting FF-ICE Release 1 implementation by 2030, interoperable information exchange will be essential to supporting more collaborative and efficient airspace management.

Singapore’s experience demonstrates that SWIM is an important foundation for future operational capabilities that depend on timely, reliable and standardised information sharing.

Turning Shared Experience into Collective Progress

CANSO’s contribution to ICAO’s SWIM in Practice video series reflects a commitment to supporting practical implementation and strengthening collaboration across the global ATM community.

By bringing together the CANSO SWIM Implementation Kit and CAAS’s real-world experience, the video aims to make SWIM more tangible and demonstrate that meaningful progress can begin with manageable, practical steps.

It also reinforces the importance of knowledge sharing. As more ANSPs progress with SWIM implementation, exchanging experiences, challenges and lessons learned will be essential to accelerating adoption and strengthening interoperability across regions.

The path towards a more connected global ATM system is built on common standards and guidance, brought to life through practical implementation and collaborative action.

CANSO extends its appreciation to ICAO for this valuable initiative and to David Leow, Elvin Liow and CAAS for sharing their experience and supporting the wider aviation community.

Through continued collaboration, practical guidance and the sharing of operational experience, CANSO remains committed to helping ANSPs advance their SWIM implementation journeys and supporting the digital transformation of global ATM.
