A monitoring system for detecting failures, or impending failures, in subsystems of a fly-by-wire primary flight control system of an aircraft. The system monitor a critical variable of at least two controllers acting in concert, in real time. Differences between the critical variables are calculated and, after filtering to remove insignificant variations, structural fatigue damage is estimated based on significant detected variations. Depending upon the relative severity of the estimated fatigue damage, the aircraft's primary flight control computer is ...
[ The embodiments of the invention in which an exclusive property or privilege is claimed are defined as follows:] [1.] A method of monitoring subsystems of a fly-by-wire primary aircraft flight control system, the method comprising:(a) communicating signals representing loads from each of a first and a second aircraft flight control surface controller to an aircraft onboard digital signal processor, said controllers normally operating in concert;(b) periodically determining a difference between magnitudes of loads of the first and the second controllers...
