In earlier analogue avionic systems the number of cables used to transfer information between the various system components was considerable. With these systems, at least one pair of wires has been required for each signal and so a typical installation requires several pairs of wires. With the equivalent digital systems, all the analogue signals are converted into their equivalent and are assigned unique address labels to ensure there are no conflicts. These signals are then transmitted down a single pair of wires, which makes up a data bus. Aircraft data bus systems allow a wide variety of avionics equipment to communicate with one another and exchange data. The type of language used on an aircraft data bus is known as the protocol. There are currently different data bus standards (protocols) that currently account for most of the avionics data interchange on today's aircraft, and these are: ARINC 429, ARINC 629, MILSTD 1553, MIL-STD 1773, CSDB and ASCB. In this study after evaluating the main characteristics of data transmission and data bus used aircraft systems, ARINC 629 standard examined in detail.
