ABSTRACT
ARINC specifications 419, 429, and 629 and Project Paper 453 are documents prepared by the Airlines Electronic Engineering Committee (AEEC) and published by Aeronautical Radio Inc. (ARINC). These are among over 300 air transport industry avionics standards published since 1949. 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. The differences between the systems are described in detail in the subsequent sections.
