UK CAA
The UK Civil Aviation Authority (CAA) is the national aviation authority responsible for regulating civil aviation in the United Kingdom. Following Brexit, the UK CAA took over regulatory responsibilities from EASA for UK airspace and has implemented a risk-based framework for drone operations. The UK maintains a system similar to the EU with Open, Specific, and Certified categories for drone operations, with specific focus on registration requirements, pilot competency, and upcoming UK-specific class markings and Remote ID regulations.
