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 Overseas Territories Aviation Circular provides information regarding Electronic Flight Bags and the requirements of both the AN(OT)O and OTAR Parts 39, 121, 125 and 135 for obtaining an approval. This guidance is also intended to provide an indication of the level of knowledge and investment in resources (both human and hardware) necessary, before an operator is ready to commence the process of applying for an EFB approval.


This Circular relates to the use of Electronic Flight Bags (EFB) in accordance with OTAR Parts 39, 121.800, 125.800 and 135.800.


First issue.
