A.C.A.R.S. stands for Aircraft Communications Addressing And Reporting System. This is an air - ground - air radio data system, developed by Aeronautical Radio Inc. (ARINC) in the 1970's, for commercial aircraft. Data sensors on board the aircraft register "events" which are fed into a computer to be converted into data packets to be sent to ground stations via the aircrafts normal VHF voice radio. The receiving ground system routes the data packets, via ARINC's Electronic Switching System and central computer then to the relevant carrier.
