Abstract: UAV fault prediction，an important part of unmanned aerial vehicle (UAV) fault detection，is effective in reducing the malfunction occurrence rate of UAV. In this paper，the test data of UAV was analyzed by using math-ematical statistics based on the theory of statistical process control. The fault prediction system was designed and its working principle and working process were described by analyzing the five kinds of fault data commonly oc-curred. This system would be valuable and helpful for technicians to find the potential faults of UAV and to tell the real alarms from the false ones. The system has satisfactory capability and value.
