The rapid development of the software system of airborne equipment presents a severe challenge to the mainstream airborne software architecture at home and abroad. It is necessary to design and study the software architecture of the new generation aeronautical airborne equipment. This paper analyzes the development of the software architecture of airborne equipment, and studies the latest software architecture technology in current computer industry. This paper probes into the technical ideas and design scheme of the software architecture of the new generation aeronautical airborne equipment and compares it with the key performance indexes of different architecture software to show the effectiveness of the design scheme.
