The invention relates to an error tolerant adjustment system comprising at least one servo tab (A1, A2; B1, B2) that can be adjusted on respectively one of the carrier wings of an aircraft and comprising a control and monitoring device (5). Said adjustment system comprises drive devices (PA1, PA2, PB1, PB2) that are functionally connected to the adjusting and monitoring device (5), each drive device being associated with each servo tab (A1, A2; B1, B2), and each drive device respectively comprising two drive motors (M1, M2), two braking devices (B1, B2), each braking device (B1, B2) being associated with each drive motor (M1, M2) and being used to block the output of the respective drive motor (M1, M2), a differential couples the outputs of each motor is such a manner that they are accumulated, an output shaft for coupling the output of the differential to drive connections (51, 52) and a differential lock (D) that is functionally connected to the control and monitoring device (5), said lock being coupled to the control and monitoring device (5) in such a manner that each braking device (B1, B2) and the differential lock (50) can be actuated by a command signal of the control and monitoring device (5); and adjusting devices (A11, A12, A21, A22; B11, B12, B21, B22) to which the drive device (PA1, PA2, PB1, PB2) associated with the servo tabs (A1, A2; B1, B2) is coupled, each adjusting device comprising a transmission gearing (20), an adjusting mechanism (21) and a position sensor (22) that is functionally connected to the control and monitoring device (5) for determining the adjusting state of the servo tab; the control and monitoring device (5) comprises a control function for controlling command signals for the drive motors (M1, M2) for adjusting the servo tab.
