Abstract:Software model-based development technology has been widely used in civil aviation airborne equipment area because of its convenience of visual modeling and simulation, automatic code generation and so on. More and more airborne software developed by MBD technology has brought significant challenges to the airworthiness compliance of civil aircraft on software. In order to solve this problem, at the end of 2011, the American Aeronautical Radio Technical Committee issued DO-178C as an airborne software compliance method recognized by the civil aviation industry, and on this basis, it issued DO-331 as a supplement to the airworthiness compliance requirements of airborne software MBD technology. Based on the research of MBD objectives in DO-178C and DO-331 standards, combined with engineering practice, this paper summarizes a set of engineering monitoring process requirements of main civil aircraft manufacturers for using MBD technology to develop embedded software suppliers of airborne equipment, which helps to improve airworthiness confidence, so as to provide reference for main manufacturers and suppliers in processing MBD software.
