Formal specification and verification of a fault-masking and transient-recovery model for digital flight-control systems:

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 comput...

Summary: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."
