Safety and Hazards Analysis for Unmanned Aerial Vehicle System

Abstract

The tactical performance and advantages of unmanned aerial vehicle (UAV) system will make it play an increasingly important role in future high-tech wars and civil aviation. However, due to the different characteristics of manned aircraft (MA) and UAV flight accidents, the safety analysis and management measures of MA are not fully applicable to UAV system. Firstly, the flight accidents of UAV system are analyzed statistically, and the characteristics of UAV system accidents are obtained. Then, the safety analysis of MA is used for reference, and the safety of UAV system is defined. The severity level of UAV system accident and the corresponding risk acceptability are proposed. Finally, from three aspects of the design, unit training and operation the hazard sources are analyzed. The classification of the probability of the occurrence of the unsafe events and the qualitative analysis of the dangerous sources proposed in this paper can lay a foundation for the construction of the following UAV safety management framework.
