The Director of Civil Aviation (DCA) has overall responsibility to ensure the safety and security of civil aviation in the Bailiwick of Guernsey and its airspace. The DCA is a shared post with the Bailiwick of Jersey. The DCA publishes a regulatory guide called the Aviation Journal that contains advice, guidance, policy and notices. This site also contains specific technical requirements and information circulars associated with registering an aircraft in Guernsey.
