An aircraft system monitors health of passive safety brakes on a plurality of auxiliary lift wing devices of an aircraft wing. The wing includes an actuator driveline, and a plurality of actuators are secured to the driveline for extending and retracting the auxiliary lift wing devices. Each actuator incorporates a passive safety brake, and a flight computer enables the actuators to synchronously extend and retract the auxiliary lift wing devices. Torque sensors are fixed to the actuator driveline, each torque sensor being positioned adjacent an actuator for sensing static torque values at that actuator location. When an aerodynamic load acting on any one extended auxiliary lift wing device creates a higher static torque value at one actuator location relative to others, the aircraft system generates a warning signal and/or message to indicate occurrence of a potential safety brake failure within the one actuator.
