CAP 413 SI 2024/01: Special Use Airspace Activity Information and Crossing Services

Supplementary Instruction CAP 413 Number: 2024/01 has been published by the UK CAA. The purpose of this Supplementary Instruction (SI) is to detail changes being made to the Radiotelephony Manual (CAP 413) with effect from 22 April 2024.

The SUA Policy Statement amends the terms danger area crossing service (DACS) and danger area activity information service (DAAIS) to SUA crossing service and SUA activity information service. This change necessitates amendment to CAP 413 to ensure that it correlates with the SUA Policy and to provide clarity on what the two services provide.

These changes are largely editorial with little effect on the RT phraseology.

AIP ENR 1.1 Section 5 is undergoing extensive amendment at the next available AIRAC to reflect the introduction of the SUA Policy. For further information, please review the airspace policy statement which can be downloaded from the CAA’s website.

Annex A of this document details the amendments to phraseology that will apply with effect from 22 April 2024.
