Today’s avionics systems engineers face tremendous challenges.
More than ever, avionics systems engineering is about integrating a diverse range of functionally complex components provided by multiple suppliers into a system that’s reliable enough to ensure consistent aircraft performance and passenger safety.
These challenges include understanding innovations in individual avionics components such as navigational systems, autopilot, radar, collision avoidance and braking systems, which provide military and commercial pilots with an advanced toolkit that makes flight safer and more controlled.
This means continuing education in avionic systems is more important than ever. For example, it’s crucial to know how to create cutting edge, well-integrated, robust systems architecture to generate an Interface Control Document (ICD) – a large spreadsheet that gathers data and inputs from multiple avionics system suppliers and accurately reflects all system components interactions and interdependencies. This includes hardware and software redundancies, message hierarchies, data inputs and communication switches.
Avionics systems engineers also need to understand and meet numerous regulatory operating systems protocols including ARINC 653, ARINC 429, CAN, and ARINC 664 and documents such as DO-178C and DO-254.
DO-178C is a particularly important document for everyone in the avionics systems engineering field to know thoroughly.
DO-178C is the Software Considerations in Airborne Systems and Equipment Certification. This is the primary document by which certification authorities such as the FAA, EASA and Transport Canada approve all commercial software-based aerospace systems. The document is published by RTCA, Incorporated, in a joint effort with EUROCAE, and replaced DO-178B.
The FAA has made DO-178C a recognized acceptable means for showing compliance with the applicable airworthiness regulations for the software aspects of airborne systems and equipment certification.
