Radio & Transponder Mandatory Zones

As part of our work to enable the Airspace Modernisation Strategy, the CAA has reviewed and amended its policies on radio and transponder mandatory zones (RMZ and TMZ).

This has resulted in:

# new acceptable means of compliance and guidance material to SERA.6005 Requirements for Communications and SSR Transponders adopted through ORS9 CAA Decision No 10;
# an amended airspace Policy For Radio Mandatory Zones and Transponder Mandatory Zones on the design and establishment of RMZ and TMZ; and
# revisions to the MATS Part 1 (CAP 493), the FISO Manual (CAP 797) and the Radiotelephony Manual (CAP 413)

which come into effect on 24 March 2022.
