“…The system safety assessment from the FMEA is used to guide application software developers in certain life-cycle processes. These processes include design reviews, coding practices, verification and testing, and integration, all of which are commensurate with the required level of safety derived from the FMEA [11].…”

Integrated modular avionics systems present new opportunities and benefits for developing advanced aircraft avionics, as well as a series of challenges related to hazard analysis and certification. This paper addresses some of those challenges and proposes a new procedure for improving hazard analysis of integrated modular avionics systems. A significant objective of integrated modular avionics architectures is the ability to develop individual software applications independently and then integrate those applications onto one platform. It has been very difficult for both designers and certifiers to understand and predict how the system will behave when the applications are integrated into one system. Traditional fault-based hazard analysis techniques are limited with respect to this problem. Therefore, this paper uses a different technique, called Systems-theoretic Process Analysis, to identify hazardous behavior that emerges when individual applications are integrated. Systems-theoretic process analysis is a systems-theoretic hazard analysis technique that accounts for hazardous behavior due to component interaction, including cases when the components have not failed or faulted. Systems-theoretic process analysis is extended in this paper to account for behavior that emerges when software applications share data, which is a requirement in aircraft systems. The paper illustrates the new approach with an example that includes real-world avionics functions.
