ABSTRACT
Aeronautical Radio Incorporation (ARINC) specifications 419, 429, and 629 and Project Paper 453 are documents prepared by the Airlines Electronic Engineering Committee (AEEC) and published by ARINC. These documents, commonly referred to as ARINC 419, ARINC 429, ARINC 453, and ARINC 629, describe data communication systems used primarily on commercial transport airplanes, but which are also used by general aviation and military airplanes. ARINC specification 419, "Digital Data Compendium", provides detailed descriptions of the various interfaces used in the ARINC 500 series of avionics standards prior to 1980. ARINC specification 429, "Digital Information Transfer System (DITS)", was first published in 1977 and has since become the ARINC standard most widely used by the airlines. ARINC Project Paper 453 was developed by the AEEC in response to an anticipated requirement for data transfer rates higher than achievable with ARINC 429.
