Abstract
The present invention relates to an aircraft high-lift system with at least one drive unit for operating the high-lift systems of the half wings (half-wing systems) and with at least one overload protection to avoid undesirably high operating torques in the half-wing systems, wherein the overload protection includes a comparator, by means of which the instantaneous values of the operating torques of the half-wing systems are compared and/or a condition caused by the difference of the operating torques is detected, and a limiter connected with the comparator, by means of which the drive unit is blocked, shut down or deactivated, and/or the torque of the drive unit is dissipated into the aircraft structure, when the difference of the operating torques determined in the comparator exceeds a limit value.
