Abstract: A fail operational/fail passive automatic pilot system for controlling or positioning a control surface of an aircraft is disclosed. This system utilizes two computer assemblies, each including two redundant computation channels. The four computation channels receive signals from fail operational/fail passive sensor sets made up of two monitored and three unmonitored sensors. Each computation channel generates a redundant channel signal which is crossfed to each of four signal selectors. The signal selectors select signals for controlling and monitoring system operation. Failure logic associated with each signal selector suppresses sensor and system faults to achieve fail operational/fail passive system operation.
