Recent statements by the FAA regarding commercial aircraft certification guidelines indicate that structural elements have to be considered in safety analysis of flight control systems in a wider scope. The monitoring of failure modes within the drivetrain is expanding to include the kinematics and control surface itself. Among other aspects, this leads to implications for the high-lift system, since it is unclear if structural defects can be reliably detected by conventional fault detection systems, such as angle sensors on the drivetrain or torque sensors at the drive unit. Consequently, this has to be investigated and alternative monitoring concepts have to be considered to meet the new requirements. This paper presents a study of a new monitoring concept for future leading edge slat systems using a virtual test environment. Utilizing a co-simulation consisting of MSC Adams for the flexible multibody simulation and Matlab Simulink/Simscape for the modelling of the drive train, the functionality and performance of a use-case monitoring concept for future leading edge slats based on position sensors is investigated based on various test cases.
