Overseas Territories Aviation Circulars are issued to provide advice, guidance and information on standards, practices and procedures necessary to support Overseas Territory Aviation Requirements. They are not in themselves law but may amplify a provision of the Air Navigation (Overseas Territories) Order or provide practical guidance on meeting a requirement contained in the Overseas Territories Aviation Requirements.


This Circular provides guidance regarding checks that an aerodrome may carry out to provide assurance that the ‘obstacle surveyor’ has provided accurate and useable survey data.


This Circular relates to OTAR Part 139.


Second issue.
