Main force transmission channel failure detecting device for aircraft, has comparator utilizing difference between position information provided by position sensor assemblies to detect failure of main channel

摘要

The device has a position sensor assembly (26) installed on a structure (11) of an aircraft and driven directly by a flight control surface (10). Another position sensor assembly (21) is installed on a flight control actuator (18) that controls position of the surface (10). A comparator (30) utilizes difference between position data provided by the assemblies to detect failure of a main channel.
