Overseas Territory Aviation Regulations (OTAR) Part 145 & Part 39 Combined Training – 4 Days


The Overseas Territories Aviation Requirements (OTARs) describe the means by which aircraft operators, aviation personnel, and providers of services can gain approvals, licenses, and certificates and the process through which these are maintained. This process ensures adequate levels of safety and internationally agreed standards are met.

Overseas Territories Aviation Circulars (OTACs) are issued to provide advice, guidance, and information on standards, practices, and procedures to support the Overseas Territories Aviation Requirements (OTARs). They may amplify or provide practical guidance on meeting a requirement. They may also contain administrative material, information of a temporary nature, or information published in advance of a formal amendment to OTARs.
