Method for monitoring the operation of an aircraft piloting device and an aircraft piloting device thus monitored
First Claim
1. A method for monitoring the operation of an aircraft piloting device comprising:
- at least one piloting member (20, 30);
at least one fly-by-wire flight control system (40, 41) adapted to generate, as a function of predetermined control laws, signals for controlling actuators (23, 33) of flight control members of said aircraft at least as a function of signals, called primary signals, delivered by sensors associated with each piloting member,said method for monitoring operation being adapted to detect operating anomalies within said piloting device and to generate corresponding monitoring signals (55, 56) and comprising the following steps;
computing, on the basis of at least part of signals delivered by sensors associated with each piloting member and according to at least one predetermined computation law, at least one theoretical value of at least one operating parameter, called monitored parameter, of at least one piloting member (20, 30);
comparing, for each monitored parameter, each theoretical value with measurement signals delivered by sensors associated with at least one piloting member;
selecting a monitoring action as a function of the difference between each theoretical value and said measurement signals,characterised in that said at least one theoretical value is computed on the basis of at least part of said primary signals, and in that it is implemented by at least one monitoring module (53, 54) integrated into a fly-by-wire flight control system (40, 41).

Abstract
A method for monitoring an aircraft piloting device including at least one piloting member (20, 30) and at least one fly-by-wire flight control system (40, 41). At least one monitoring module is integrated into this control system and is adapted to compute, on the basis of primary signals processed by sensors associated with at least one piloting member, at least one theoretical value of at least one monitored parameter of at least one piloting member, to compare each theoretical value with measurement signals of each monitored parameter and to select a monitoring action, particularly to generate monitoring signals (55, 56), as a function of the difference between each theoretical value and the measurement signals.
