The most formidable challenges of modern avionics development programs are often centered around the safety certification process and the corresponding requirements and costs. Equally as challenging to any large development program are the design... Read More

Overarching Properties: An Alternative to DO-178

_______________ Overarching Properties—an alternative design assurance approach to DO-178C—marks the biggest change in airborne software safety certification since DO-178B was unveiled in 1992. Intended to be more efficient and flexible than... Read More

What is a Reusable Software Component?

A DO-178B/C Reusable Software Component (RSC) is a software collection that is recognized as meeting the requirements of RTCA/DO-178B/C and that may be used on more than one project without having to regenerate certification artifacts. The FAA... Read More

CAST-32A: Significance and Implications

_______________ CAST-32A presents the coordinated position of avionics certification authorities regarding Multi-Core Processors (MCPs). While today’s aerospace ecosystem could benefit from the use of MCPs, before CAST-32A was published, FAA/EASA... Read More
