Unmanned Aircraft System Operations in UK Airspace – SAIL Mark Policy Concept
The CAA (UK Civil Aviation Authority) has published a new SAIL Mark Policy Concept as of 6th March 2025.
This policy is outlined in CAP 722K: “Unmanned Aircraft System Operations in UK Airspace – SAIL Mark”, which is intended for UAS designers and Recognised Assessment Entities for Flightworthiness (RAE(F)).
It provides the requirements, administrative processes, and guidance for the delivery of a Specific Assurance and Integrity Level (SAIL) Mark certificate, for a UAS to be operated within the Specific Category in the UK.
While CAP 722K is available for immediate use, it remains a Policy Concept, meaning certain elements may be refined over time. As this is a new process, the CAA will be actively collaborating with industry over the time to assess its implementation, gather insights on its use, and identify areas where additional or refined guidance may be needed.
