Reliability, maintainability and safety applied to a real world avionics application

摘要

NLR currently co-develops a civil avionics application that connects ircraft subsystems with the aircraft flight deck by means of modern digital data buses. It combines, controls, processes and forwards the data between the subsystems and flight deck. High reliability of these functions is required to ensure the safety of the a iraft. For this kind of applications certification is required by an independent, government authorised, third party. Guidelines for this certification are documented in the DO-178B standard: software considerations in airborne systems and equipment certification.
