The Certification of Airborne Electronic Hard (DO-254) course is a two-day course geared for the hardware engineer, technical manager or project manager wanting to understand DO-254 compliance in the greater context of certification as well as within the myriad of supplemental policy documents that now define what it means to comply with DO-254.

In 2008, the FAA awarded Patmos Engineering Services the contract for developing and delivering the “Complex Electronic Hardware” training course that was taught at the FAA Academy to DO-254 program auditors.

From this experience and these materials, Tammy Reeve, President of Patmos Engineering Services, developed this DO-254 course offering for DO-254 applicants. Today, Tammy has taught this course to over 40 companies around the globe. The feedback has been overwhelmingly positive.

Tammy was also selected as the primary developer for a military specific training on DO-254 and has delivered this training for multiple sites with great reviews.

Patmos offers this and several other industry leading compliance training courses, which can be delivered on-site or on-line, and can be tailored to your specific needs. You can also pair these classes with any other Patmos offering (such as a process “Gap Analysis”) for a fully customized services package.
