Abstract: A fixed wing unmanned aircraft and a method for operating the same are provided. The fixed wing unmanned aircraft may include, but is not limited to, a failure detection system configured to detect faults in one or more of the plurality of components, a capability evaluation system communicatively coupled to the failure detection system, the capability evaluation system configured to determine a capability level of the fixed wing unmanned aerial vehicle based upon the faults in the one or more of the plurality of components, and a trajectory generation system communicatively coupled to the failure detection system and the capability evaluation system, the trajectory generation system configured to generate a touch down trajectory for the fixed wing unmanned aerial vehicle based upon the determined capability level of the fixed wing unmanned aerial vehicle, wherein when the determined capability level is below a predetermined threshold, the touch down trajectory comprising a stall maneuver configured to minimize a lateral energy of the fixed wing unmanned aerial vehicle.
