Definition
A private company, originally established by the airlines in 1929, that provides communication services and infrastructure to aviation. ARINC operates ground radio stations that relay messages between aircraft and airline operations, air traffic control, and weather services, particularly over oceanic and remote areas where direct VHF coverage is unavailable.
Plain English
A long-established company that runs the radio network airlines and pilots use to send messages back and forth — especially when flying over oceans or remote regions where normal radio doesn't reach.
Context Anchor
Seen in weather and flight-planning material when aircraft reports or other flight messages are being passed between an aircraft and ground services.
Derivation
The name comes from 'Aeronautical Radio, Incorporated.' The company was formed in 1929 by the airlines to coordinate radio frequencies and avoid interference, and the name has stuck ever since even though its services have grown well beyond simple radio.
Why Pilots Care
Pilots flying long-range or oceanic routes use ARINC services to stay in contact with company dispatch, file position reports, and receive weather information when they are out of normal ATC radio range.
Intuition Check
ARINC is not a cockpit radio or a single radio frequency. In this context, it refers to the aviation communication service that carries messages between aircraft and the ground.
Example Sentence 1
Crossing the Atlantic, the crew passed their position report to ARINC, who relayed it to oceanic ATC.
Example Sentence 2
Pilots receive consistent weather products because ARINC maintains the data exchange protocols used across the system.
