ICAO 3 Letter Designators

The CAA Safety & Airspace Regulations Group (SARG) is responsible for the policy and acceptance of requests for ICAO 3-letter Aircraft Operating Agency Designators and ICAO Telephony Designators within United Kingdom airspace and this continues to apply to the Isle of Man.

UK policy is based upon ICAO documents 7910 and 8585.

The procedures are published in the latest Aeronautical Information Circular (AIC Yellow – Operational Matters) entitled “UK Policy for the Assignment and use of ICAO Location Indicators, 3-Letter Designators and Telephony Designators” which can be found on the NATS website.
