Method for predicting a trailing edge flap fault

摘要

A method 100 of predicting a trailing edge flap failure includes receiving a position signal 102 from the position sensor indicative of the position of at least one of the trailing edge flaps and comparing the position signal to a reference position value to define a position comparison 104. A variation parameter 106 is determined and which provides an indication of the variation of the position signal from reference values. The variation parameter is compared to a reference variation value to define a variation comparison 108. The variation comparison provides an indication 112 for the prediction of a trailing edge flap failure or fault 110.
