UK Civil Aviation Authority updates Airspace Change Process to reduce red tape and speed up reform

The UK Civil Aviation Authority (CAA) has updated its Airspace Change Process to reflect new Government policy outlined in the Air Navigation Directions and Air Navigation Guidance, which come into effect on 1 October 2026.

The updated CAP1616 (Civil Aviation Publication 1616) process, also taking effect on 1 October, represents a significant reform of how airspace changes are proposed, assessed and approved. As a key enabler of the UK Airspace Modernisation Strategy, the revised framework is designed to support a more efficient and adaptable airspace system. It is a national process, and will have an immediate effect on proposed airspace changes to London areas.

The CAA said the changes will help reduce flight delays caused by capacity constraints, improve the efficiency of airspace and ensure impacts on local communities are properly considered, with consultation remaining a fundamental part of the process.

Airspace underpins every aspect of UK aviation, from commercial passenger flights and general aviation to emerging technologies and users such as drones and advanced air mobility. As demand evolves and the aviation system becomes more complex, the CAA said the ability to update and adapt airspace efficiently is increasingly important.

The update introduces a streamlined process for short-term activities, intended to enable a more agile and responsive airspace system and support innovation. The reforms also strengthen alignment between the airspace change process and wider planning frameworks, providing greater clarity for industry and enabling proposals to be dealt with more efficiently alongside planning decisions. Communities affected by airspace change will continue to have opportunities to provide feedback through consultation, with proposals assessed against their impacts.

CAP1616 remains a key framework for enabling airspace modernisation, with Government setting policy, industry developing airspace change proposals, and the CAA independently deciding whether proposals meet the required standards.

Giancarlo Buono, Director of Safety and Airspace Regulation at the UK Civil Aviation Authority, said: “Following recent changes to Government policy, the UK’s airspace must continue to evolve to support a changing aviation sector, from modernising existing operations to accommodating new technologies and users. The revised CAP1616 process provides a simpler and more proportionate framework for making these changes.

“By tailoring requirements to the scale and impact of proposals, we can reduce unnecessary burdens and help organisations make progress, whilst keeping a consistent focus on safety, evidence and impact.”
