Unmanned Aerial System(UAS)Operation Risk Assessment and Risk Mitigation Research
With the rapid development of the UAV technology,the application of the UAVs in various fields is becoming in-creasingly widespread.However,accompanying this trend are potential safety risks associated with their operation.This paper aims to construct a comprehensive risk assessment framework for the safe operation of the UAVs,with the goal of enhancing the safety and reliability of the UAV operations.Through in-depth analysis of key factors in the the UAV operation process,including flight environment,technical performance,and air traffic management,a multi-level four-stage model for the UAV risk assessment is es-tablished.The application of this model extends to the UAV pre-flight permissions and insurance.Finally,the paper proposes safety measures and recommendations tailored to different risk scenarios,aiming to provide scientifically sound risk management strategies for the UAV operations.
