Special Use Airspace Activity Information and Crossing Services

UK CAA has published Supplementary Instruction (CAP 413 SI 2024/01) which details changes being made to the Radiotelephony Manual (CAP 413) following the introduction of the Policy for the establishment and operation of Special Use Airspace (SUA), dated 12 February 2024.

This SI reflects the change in the naming of the Danger Area Activity Information Service (DAAIS) and Danger Area Crossing Service (DACS) to the new generic name Special Use Airspace (SUA) Crossing Service. This change to CAP 413 is largely editorial, and the radiotelephony calls used have not changed.
