Strength in Avionic Communication: The ARINC 429

Enabling proper communications between the various systems in an aircraft, and relaying the data back to its pilot is no easy task for their designers and manufacturers, however it is a crucial detail that engineers would be foolish to overlook. There is an assortment of new technologies constantly being developed in this regard; but for many good reasons, the ARINC 429 is still considered a standard omnibus configuration for this purpose.

Why is ARINC 429 the Dominant Transmission Standard in Avionics?

Real time transmission of information is the key to avionics success, which enable pilots to make critical decisions about the aircraft while it’s on flight. Whether it is for military or commercial purposes, ARINC 429, one of the most widely used avionics standards in the world today and among the 300 or so standards published by Aeronautical Radio, Inc. (ARINC) since 1949, is capable of 32-bit data transmission at a speed of 100 kilobits per second, two different speed configurations, unidirectional flow of data, low cost implementation and design, all with a proven record of efficiency and integrity.

Arinc 429 – about transmissions

Arinc-429 is a dual-wired computer bus data transfer system. It is manufactured by Aeronautical Radio INC (ARINC), a dominant avionics data bus corporation. A mainstay in commercial avionics data bus transfer, arinc-429 is responsible for facilitating communication in commercial aircrafts’ equipment and data systems. Today, Arinc-429 is the commercial standard for aircraft avionics. It continues to be used in modern aircraft.

Its construction is simple: a single source transmitter that is connected to up to 20 receivers via a dual twisted wire.

What Is ARINC?

ARINC (Aeronautical Radio Incorporated) is a private organization first established in 1929 that is composed of airline carriers as well as airplane and avionic equipment providers. ARINC was created in order to publish standards and requirements by the AEEC (Airlines Electronic Engineering Committee) for non-government avionic machines produced by both regional and international manufacturing companies.
