Digital Databus Theory & Analysis


As today’s modern airplanes become much more technologically advanced, so must the professionals that maintain them. The advanced avionics and instrumentation systems used in these aircraft rely on various forms of digital databus communication. Understanding digital databus theory is becoming more and more important for avionics technicians, and even A&P mechanics, to effectively test and troubleshoot these highly advanced aircraft systems.

Presented by: Azimuth Aerospace Solutions LLC - Bio 

Course Goals:

  • Digital Databus Theory and Analysis explores several formats of digital data transfer protocols commonly used in aviation RS-232, RS-422, ARINC 429, and an introduction to the MIL-STD-1553 databus. 

  • Learn integration and wiring considerations for each of these databuses in aircraft installations. 

  • ARINC 429 word and bit structure

  • How to use both a handheld and PC-based databus reader

  • Students will be able to read the data being transmitted on a digital databus and interpret the data into useful information. 

Virtual Course:

  • This course will be presented live online.
  • After registering, attendees will be emailed the information needed to connect.
  • Attendees will be emailed the course materials in digital format.
  • Attendees are required to connect with a web camera.

Taking this course is WAY better than reading a textbook that will put you to sleep. I strongly recommend it.


Great class for general knowledge of the different databus protocols, especially really understanding 429.

Larissa  P.

a must have for every avionics tech and installer!

Stuart R.

Expect good information but heavy on math and light on real world application

Austin H.

The more you know, the easier troubleshooting gets. Being that the ARINC 429 is communicating with all of your avionics, this course is providing the ground work for you to essentially diagnose any fault in any system.

Jim P.

This course provides detailed information n how to interpret raw 429 Data

Jason T.

Good to troubleshoot & learn in depth avionics

Ryan P.

Be sure to have a small amount of familiarity with DD

Andrew  M.

Great in-depth training for someone who wants to understand better the systems we work with every day.

Justin C.

A fantastic deep dive on the "gibberish" I see on the GTN 429 diagnostics. I can speak the language now.

David S.

Great - Will recommend my other employees to attend.

Corey R.

This knowledge is perfect for really expanding capabilities into avionics

Chandler F.

Great class, I learned an incredible amount about databus and how computers communicate.

Michael W.

Very informative

JuliAnne  M.

This class was intimidating, but it shouldn't have been. William made everything easy to understand.

Kenneth M.

Great course. Worth the time.

Javier Q.

Take this information

Ludwig Nicholas L.

Excellent primer to material toward a working understanding to otherwise complicated material.

Courtney M.

Excellent class, worth taking.
