Effective: on issue


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


The purpose of this OTAC is to provide information on the requirement to include in appropriate Air Traffic Services (ATS) Operations Manuals (MATS/ATS Exposition) guidance material on the use of ATS surveillance systems in the provision of an Air Traffic Control (ATC) or Aerodrome Flight Information Service (AFIS). For clarity, the use of ‘ATS’ throughout this document refers to both ATC and AFIS as appropriate.


This Circular relates to OTAR Parts 171 and 172.


First issue.


Enquiries regarding the content of this Circular should be addressed to Air Safety Support International at the address on the ASSI website or to the appropriate Overseas Territory Aviation Authority.
