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

-Timo Wolski, DO-254 Bundle student

“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

"I think the material is fantastic!"

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

"The training was very good. Your materials are very organized."

- Joe Etminan, Electronic Professor at Rock Valley College, Senior System Engineer – Aircraft Electrical System at Belcan Company
