Training: Certification of Software (DO-178C)

The Essential Elements of Airborne Software Compliance.

This course, which is a recording from a live training session held for students on July 16-17, 2020, is rich with all the essential information involved with DO-178C compliance, including many inside tips for success in your DO-178C program! If you are an engineer or manager with new or upcoming compliance requirements and are trying to understand what DO-178C entails --and how to be successful in your program -- this course is for you. This course first talks about where the policy comes from and how it fits into the overall aircraft certification process, giving the student the regulatory background of which DO-178C is a part. It introduces other documents that interface with and influence DO-178C compliance. Then the class dives into the DO-178C life cycle, exploring the compliant development process in detail, including introducing the stage of involvement (SOI) audits that will occur at various phases. Finally, the course examines the additional considerations that involve so many programs, including how to handle previously developed software, what needs to be done for tool qualification, alternative methods, software reliability models, and product service history. What the Supplements are and how to use them is also included. Emphasis is placed on understanding the RTCA/DO-178C document and how to interpret and use it most effectively.
