Introduction to ARINC-429
2 days

Prerequisites: none. ARINC-429 is a standard for avionics data communication used in commercial aircraft, defining the physical and electrical interfaces of a two-wire data bus and the data protocol for an aircraft's avionics network. This course explains how ARINC-429 facilitates data transfer between avionics systems in commercial aircraft, ensuring interchangeability and interoperability of line replaceable units (LRUs), how it transmits data in 32-bit words, with most messages consisting of a single data word. It also covers how ARINC-429 supports two data rates: 12.5 kbit/s (low speed) and 100 kbit/s (high speed) and how it uses twisted pair cables for balanced differential signaling, minimizing electromagnetic interference (EMI). This course covers how it's used for various avionics systems, including mission control computers, inertial reference systems, air data systems, altimeters, radios, and sensors.

What you will learn:

  • To understand the ARINC-429 communication protocol
  • An overview of ARINC-429 topology and installation

  • Learn how the standard operates
  • ARINC-429 data buses and system integration
  • An overview of ARINC 429-capable systems
  • Troubleshooting and maintaining
    • Avoid common errors in designing a ARINC-429 system
    • Data file transfer techniques
    • Troubleshoot an ARINC-429 system installation
