This area of the website deals with the regulation of Airports and Air Traffic Services including Instrument  Flight Procedures, Flight Checking of Navigational Aids, Emergency Planning, Safeguarding and Aeronautical Information Publications.

The requirements for aerodrome certification and Air Traffic Services (ATS) are laid down in the Air Navigation (Overseas Territories) Order (AN(OT)O) principally within Parts 16-19 (Articles 138-165).

The means of compliance with the AN(OT)O are contained within the Overseas Territories Aviation Requirement (OTAR) Parts. These OTARs are supported by Overseas Territories Aviation Circulars (OTACs) which provide further guidance on the requirements. The status and operation of OTARs and OTACs is explained in greater detail in the Requirements and Policy section of this website.

Aerodromes used for international air services require a Certificate issued by the Governor. The requirements for the issue of the certificate are contained in the OTARs, which fulfil the requirements of the International Civil Aviation Organisation (ICAO). The requirements identify standards for:

  • Aerodrome Manual
  • Aerodrome management systems
  • Obstacle Limitation Surfaces
  • Runways and approach aids
  • Taxiways
  • Technical equipment, installations and maintenance
  • Heliports
  • Aeronautical studies (risk assessments)

Since 2003, ICAO have required that aerodromes have a Safety Management System (SMS), and the OTARs also require this approach. Wherever possible we encourage Air Traffic Support and airports to produce an integrated SMS to ensure that all aspects of the airport and Air Traffic Control operations are seamlessly integrated through a structured focus on safety.

Overseas Territories Aviation Requirements

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