DO-254 Basics

Your First Step in Understanding DO-254 Compliance

This course provides the basic foundations for understanding DO-254. The materials cover where the policy comes from (i.e., the regulatory environment) and explains the role of the certification authorities. It discusses the document itself, what's in it, how to navigate and use it, and what other documents influence and interface to it. The presentations cover the DO-254 life cycle and then go into detail about how this life cycle is applied to the FPGA development cycle. The course also addresses the Advanced Verification needs presented in Appendix B, as well as the complimentary (but compulsory) guidance presented in FAA Order 8110.105 as well as EASA Certification Memo SWCEH-001. When this training is completed, the student will have a basic understanding of the why, where, what and how of DO-254 compliance. (The DO-254 Special Topics training continues by explaining many of the more difficult topics and concepts that affect most DO-254 programs).

Class Curriculum



"I think the material is fantastic!"

- Edwin C. Aulick, Engineering Professional and "DO-254 Basics" and "DO-254 Special Topics" student

"I enjoyed the training. It provided a great overview of the DO-254 topics."

-Timo Wolski, DO-254 Bundle student

“Even though I already do engineering work for DO-254 programs, this training helped fill in some gaps that I hadn’t received in other training. And it was a very convenient format for me to learn on my own time.”

- Joe Martine, FPGA Verification Engineer and Student of “DO-254 Basics” and “DO-254 Special Topics”

“Tammy’s DO-254 DER experience and Michelle’s hardware development tools and technical sales background is evident in the training material, where the combination of their talents have resulted in an in-depth, yet approachable tutorial on all major aspects of DO-254. They have created an useful source of DO-254 education, balanced with real-world examples for various lifecycle topics that help the novice get quickly up to speed with FAA expectations for DO-254 compliance, as well as giving those familiar with DO-254, insight, advice and examples that can help streamline their processes and avoid common missteps. The presentations are well organized, and are an excellent source of reference material for anyone involved with managing or creating DO-254 compliant avionics.”

- Jason Brouwer, Consultant/Certification Project Lead/Systems and Equipment DER
