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.
