This three-day course is tuned for the engineer facing compliance with DO-254 & DO-178 for the first time or simply wanting to refresh their understanding of today’s airborne software compliance processes – now including a comparison of the changes from DO-178B to DO-178C.

Since 2000, Tammy Reeve, President of Patmos Engineering Services, has been helping applicants with DO-254 and DO-178 compliance. 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 both her DO-254 and DO-178 DER auditing experience and FAA training experience, Tammy developed this course offering for anyone needing to ensure compliance to these standards. Today, Tammy has taught this course to over 40 companies around the globe. The feedback has been overwhelmingly positive.

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.
