Formal Specification and Verification of a Fault-Masking and Transient-Recovery Model for Digital Flight-Control Systems
 by Dr. John Rushby.

From Formal Techniques in Real-Time and Fault-Tolerant Systems, Chapter 5.

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.
