Our website and publications are being reviewed to update all references. Any references to EU law and EASA Access guides should be disregarded and where applicable the equivalent UK versions referred to instead.

This document sets out the Civil Aviation Authority’s policy for the establishment of, and operations within, radio mandatory zones (RMZ) and transponder mandatory zones (TMZ). It supplements acceptable means of compliance (AMC) and guidance material (GM) to SERA.6005 adopted through ORS9 CAA Decision No.10 published on 13 January 2022.
