Self-Checking Widgets for Interactive Cockpits

International audienceIn the last few years, glass cockpits are being replaced by interactive cockpits to provide a much higher level of integration. Due to their event driven nature, interactive systems offer more display and control features but also more unpredictable side effects. Exhaustive testing being impossible, fault tolerant techniques have to be considered. This paper proposes a model-based approach for adding fault-tolerance mechanisms to interactive cockpits. The contribution is focused on the implementation of self-checking widgets, being the basis for interactive cockpits
