Method and device for detecting the deployment of an aircraft control surface

The method involves determining theoretical feedback current representing a feedback command emitted by a controller (10). A parameter of the feedback command is measured by using an auxiliary sensor (21), and effective feedback current is determined by the measured parameter. Difference between the...

Beschreibung
Zusammenfassung:	The method involves determining theoretical feedback current representing a feedback command emitted by a controller (10). A parameter of the feedback command is measured by using an auxiliary sensor (21), and effective feedback current is determined by the measured parameter. Difference between the theoretical feedback current and the effective feedback current is calculated to form an error signal. Uncontrolled movement of a control surface (3) is detected if comparison value depending on the error signal is higher than threshold value during confirmation time. Independent claims are also included for the following: (1) a device for detecting uncontrolled movement of a control surface of an aircraft (2) an electrical flying command system of an aircraft.
