Abstract:
1. An aircraft control surface element skew and/or loss detection system comprising: an aircraft wing structure comprising a fixed part, a first control surface element and a second control surface element, wherein the first control surface element and the second control surface element are configured to be movable relative to the fixed part, a cable coupled to each of the first and second control surface elements such that a tensile force is applied to the cable upon skew and/or loss of one of the first and second control surface elements, a mechanical link having a first end mounted to the fixed part of the aircraft wing structure, and a second end movably mounted to the first control surface element, a movement transducer configured to detect articulation of the mechanical link, wherein a first end of the cable is connected to the second end of the mechanical link such that skew and/or loss of one of the control surface elements causes articulation of the mechanical link by movement of the second end of the mechanical link relative to the first control surface element, wherein the movement transducer is a rotary transducer connected to a first pivotable arm of the mechanical link, and wherein the mechanical link comprises a linkage comprising the first pivotable arm, and a second pivotable arm pivotably connected to the first pivotable arm and pivotably connected to the first control surface member at the second end of the mechanical link.
