The UK Civil Aviation Authority has published:
- Consultation on draft guidance for the UK Airspace Design and Coordination Services (CAP 3158); and
- Consultation on the requirements for the UK Airspace Coordination Service and associated guidance (CAP 3159).
These services are central to the Government’s approach to modernising UK airspace and will be provided by NATS (En Route) plc (NERL).
We have updated our background document Modernising the way we do airspace design (CAP 3156), which supports these consultations, and welcome your responses by 12 January 2026.
Our separate consultation on proposed changes to CAP1616, the airspace change process, is open until 18 December 2025.
