Identification codes for airspace restrictions

The CAA is amending the identification codes for airspace restrictions that apply only to Unmanned Aircraft Systems. These are published in the UK Aeronautical Information Publication (AIP) in Part 2-ENR 5.1 (Prohibited, Restricted and Danger Areas). This change only impacts the technical identification code of the airspace structures, their names and dimensions are unaffected.

AIC W 020/2026 provides further details on the background, with the revised codes published in the UK AIP (AIRAC 05/2026) on the NATS website.
