The Air Navigation Services Regulation Division of the Civil Aviation Authority of the Cayman Islands is responsible for the certification and regulatory safety oversight of Air Navigation Services Systems.
Obligations for this responsibility are based on a 1944 agreement called the Chicago Convention which organised its signators into the International Civil Aviation Organisation (ICAO). This agreement put in place a commitment to foster the growth and safety of international air transportation through compliance with Standards and Recommended Practices (SARPs) that are attached to the Convention in detailed Annexes.
The United Kingdom is a signatory to this agreement and the Cayman Islands, as one of its Overseas Territories, accepts the same commitments. The U.K. created the Air Navigation (Overseas Territory) Order [AN(OT)O] as amended, and the more detailed descriptions provided in the Overseas Territory Aviation Requirements (OTARs) to help its Territorial members to comply with these requirements.
