Airlines and other aviation stakeholders now have their first formal opportunity to shape how operational data will be exchanged across UK airspace. The UK Civil Aviation Authority has opened a public consultation on System Wide Information Management, known as SWIM, which runs from 6 October 2026 to 6 January 2027.

The UK Civil Aviation Authority is the United Kingdom’s aviation regulator, based in Crawley, West Sussex. It is running the consultation as part of the UK’s Airspace Modernisation Strategy, and responses will feed into future airspace policy.

SWIM sets the standards, infrastructure and governance for the secure, interoperable exchange of aviation information. It is intended to support data-driven air traffic management as crewed and uncrewed aircraft increasingly share the same airspace.

The regulator likens the aim to the compatibility standards that let devices such as headphones and smartphones work together. SWIM is not a single IT platform or product, and instead defines how information is shared rather than where it sits.

The CAA says SWIM maintains alignment with ICAO’s Global Air Navigation Plan and creates the digital environment needed for beyond visual line of sight operations. The consultation asks industry which SWIM components are needed and what guidance should support the transition to a digital, information-centric operating environment.

The timetable beyond the consultation is already set out. The regulator plans to publish a SWIM Technical Architecture and Operational Scenarios for crewed users in 2027, followed by a final Implementation Framework in 2028.

For aircraft operators, several questions remain open. The regulator has not yet set out compliance obligations, implementation deadlines or cost estimates, and has not said whether airlines will need to fund system or avionics upgrades to connect to SWIM.

For the sector, the consultation gives airlines an early window to influence the standards and guidance that will define how they exchange operational data, ahead of the technical architecture due in 2027.
