Authors Abstract
Content
This paper aims at discussing the use of dissimilar hardware architecture to mitigate DESIGN ERRORS in a flight control system application, as one of the possible design techniques that, combined with the usage of development processes, will satisfy the safety objectives for airborne systems. To accomplish its purpose, the paper starts by understanding the origins of DESIGN ERRORS in micro-coded devices and the concerns of airworthiness certification authorities (or simply certification authorities from now on). After that, an overview of the aeronautical industry efforts in terms of development processes and certification requirements to mitigate DESIGN ERRORS will be presented. At this point, the dissimilar architecture is proposed as an effective mean to mitigate the problem of DESIGN ERRORS. Finally, a Flight Control System application using dissimilar architecture is proposed as a case study. The discussion and the case study show that dissimilar hardware architecture is an effective way of mitigating DESIGN ERRORS in a flight control system application.
