On their wings, aircraft have slats on the front side and flaps on the rear side which act as buoyancy aids. If these are extended unevenly or on only one side, this can cause significant problems in terms of the aerodynamics of the aircraft. Slats and flaps are retracted and extended by spindle drives. The respective spindle is connected to the drive motor in the gear bay via the drive shaft. A Wing Tip Brake is positioned on the shaft in the outboard wing area. This not only avoids any uneven extension of the slats and flaps, but also prevents any uncontrolled movements of the floating head due to external influences. In its function as a switch, the ‘induSENSOR IS-5-C-CR/WTB’ inductive sensor from Micro-Epsilon checks the position of the brake shoes.
