This results in new requirements for high-lift systems. Conventional monitoring sensors, such as angular position sensors on the drive shaft or torque sensors at the drive unit, focus on detection of failures in the drivetrain rather than structural defects at the inematics or control surfaces. In a previous paper the authors identified the need for a new monitoring solution to fulfil these new requirements. A high potential concept consisting of position sensors monitoring the kinematic movement was identified via virtual testing. Another promising monitoring concept and the validation of the previously utilized modelling method via a test rig are presented in this paper. For this purpose, the test results for a multitude of failure scenarios are presented, analysed and compared to the findings of the virtual tests. Based on the outcome, additional insights of the validation process will be shared, and the most promising monitoring concept for skew detection will be proposed.enleading edgemonitoringskew detectionslatsystem architecturetest rigvalidationTechnology::600: TechnologyConference Paperhttps://r3asc25.sciencesconf.org/data/pages/R3ASC25_Final_program_21may25.pdfhttps://r3asc25.sciencesconf.org/data/pages/R3ASC25_summary_26may25.pdfINSA ToulouseConference Paper
