Abstract	Honeywell Labs has been researching and developing together with NASA Langley Research Center (LaRC) algorithms for aircraft failure management and recovery. The algorithms have been integrated into a Control Upset Prevention and Recovery System (CUPRSys) that provides control law reconfiguration, fault detection, fault isolation and pilot cueing. This talk describes the capabilities of CUPRSys and the results from an evaluation of CUPRSys by an experimental test pilot in the Integration Flight Deck (IFD) at LaRC. Also discussed in the talk are details about the IFD and the MATLAB simulation environment used for design. The piloted evaluation was performed at three flight conditions and the results for one representative maneuver are presented. Pilot ratings were obtained for maneuvers for the un-failed aircraft, for the failed aircraft without reconfiguration and for the failed aircraft with reconfiguration. Only reduction of surface effectiveness faults were considered. The piloted simulation results suggest that CUPRSys provides a robust control law with promising fault detection, isolation and reconfiguration capability.
