Update to Transponder Mandatory Zone (TMZ) Information in the UK AIP

From AIRAC 12/25 (effective 27 November 2025) existing TMZs currently notified in the remarks column in ENR 2.1 will also be notified in the TMZ table in ENR 2.2 of the UK Aeronautical Information Publication (AIP).

This publication improvement is designed to make TMZs easier to locate and reference during flight planning, and is part of the CAA’s ongoing work to improve the publication of airspace information in the AIP. Further updates will follow to publish all UK TMZs and Radio Mandatory Zones (RMZ) in tables within ENR 2.2.
