The ARINC 429 governs the point-to-point data communication bus in which the transmitter connects to one of more receivers through a wired connection.
The ARINC 429 standard defines the physical, electrical and protocol requirements.
ARINC 429 specifies the requirements for an avionics communication line in terms of electrical, physical, data format, protocol and other characteristics. This allows compatible avionic systems that range from sensors to computerized control equipment, to communicate with ease regardless of the manufacturer and complexity.
This is important because a big benefit of ARINC 429 is that it allows interoperability and coexistence of different parts from manufacturers. This makes it possible for navigation systems, GPS, autopilot, fuel management, climate control, cabinet oxygen control, and computerized systems in an aircraft to interface and talk to one another.
Other advantages of ARINC 429:
- Allows digital systems in commercial aircraft to communicate with each other using standard data formats and structures over a standard physical communication bus and interfaces
- The universal structures for data and power systems give the designers of aircraft and avionics
systems the freedom to develop and create a wide variety of innovative products.
- Makes it easy to fit new technologies into the existing systems
- Simplifies the designing and implementing complex data and control systems in the aircraft as well as making it easy to maintain, repair and upgrade the systems.
Today’s applications with ARINC 429 are wide and varied, and include:
- Flight control
- Guidance systems
- Flight data
- In-Flight entertainment systems
- Navigation Systems
