More and more advanced aircraft systems are equipped with Integrated Modular Avionics (IMA) system, which presents a series of challenges related to fault detection and reporting. This paper addresses some of those challenges and proposes a new Health Management (HM) architecture for a typical distributed complex IMA system. A significant objective of this HM architecture is to ensure that the IMA system integrity and availability meet the system safety requirements. Due to the highly complexity and the integration of IMA system, it is very difficult for both designers and verifiers to develop a practical HM application in charge of detecting, isolating and reporting failures to the related hosted applications and other non-IMA systems. For this purpose, this paper proposes a new IMA health management logic for fault isolation and reporting.
