A hydraulic asymmetry detector for sensing differential movement of a pair of flight control surfaces, such as the wing flaps of an aircraft, which are actuable by actuating mechanisms. The detector has a pressure-regulator valve and a sensor valve, with the pressure-regulator valve operable in response to movement of one actuating mechanism to set a control pressure proportional thereto, and the sensor valve has a valve member which senses a force balance between a force created by the control pressure and a force which is proportional to the movement of the other actuating mechanism. The sensor valve member moves with a snap action when there is a force imbalance to result in setting one or more brakes for the actuating mechanisms to lock the actuating mechanisms and thereby limit the asymmetric condition within a manageable range.
