Small Unmanned Aircraft: Congested Areas Operating Safety Case (CAOSC)

The purpose of this Information Notice is to inform operators of civil Unmanned Aircraft Systems, wishing to operate in congested areas, of the requirement to submit a safety case for assessment by the CAA. The assessment will consider all elements of the operations (including airworthiness). Whilst this Information Notice is mainly aimed at Small Unmanned Aircraft (SUA) and Small Unmanned Surveillance Aircraft (SUSA), Unmanned Aircraft Systems (UAS) in other categories may be allowed to use the safety case approach when applying for permissions or exemptions; prior agreement from the CAA must be granted in such cases.
