In-flight detection of wing flap free wheeling skew

摘要: A method for detecting freewheeling skew failures in the wing flaps of an aircraft includes measuring outputs flap sensors when is flight (IF) and are extended to a selected position, next on ground (OG) position. The respective differences between IF OG symmetrical pairs computed, then difference computed output each pair computed. compared with predetermined maximum minimum threshold value determine whether failure exists any aircraft.
