The airspace change design proposes to optimise the UK ATS route network, where 2 primary flows of traffic to the north and south traverse the ‘spine’ of the UK, with 10 parallel routes, 5 northbound, and 5 southbound. This change is a step towards systemising UK airspace, reducing tactical intervention, allowing aircraft to follow planned routes, optimise profiles for time and fuel savings, and ensure compatibility with MTMA and LTMA modernisation projects.

The new structure will be wholly contained within controlled airspace; the lower/upper vertical limit within FL070 – FL460.

Further information and consultation responses can be provided via Citizen Space.
