Abstract: We present a formal model for fault-masking and transient-recovery among the replicated computers of digital flight-control systems. We establish conditions under which majority voting causes the same commands to be sent to the actuators as those that would be sent by a single computer that suffers no failures. The model and its analysis have been subjected to formal specification and mechanically checked verification using the Ehdm system. Keywords: digital flight control systems, formal... (Update)

.... was the formal specification and verification of a model for fault masking and transient recovery in digital flightcontrol systems [24]. The interest here is that the formal development in Ehdm was undertaken in parallel with a similarly detailed development using conventional...

...designed for the specification and proof of digital systems. The PVS system had some really significant applications in the past, e.g. Rus92, SM95, MS95] The PVS specification language builds on classical typed higher order logic. PVS views proof generation as a process with...
