The risk of damage caused by intelligent unmanned aerial vehicle activities is relatively high,and the risk of machine autonomy failure cannot be eliminated,which may trigger new types of in-fringement.It still meets the characteristics of highly dangerous activities,and its infringement regulation should still follow a strict liability path.The autonomous flight activity of intelligent unmanned aerial ve-hicles is the machine autonomous activity,and its infringement behavior should be evaluated as the phys-ical infringement behavior.Due to the uninterpreted nature of the autonomous decision-making process of artificial intelligence and the opacity of behavioral logic,intelligent drone manufacturers lack the ability to predict infringement behavior of intelligent drones in advance.Therefore,product liability applies to institutional gaps such as the defense of risks in the development of intelligent unmanned aerial vehicles,which will create a hollow path for victims to seek remedies for infringement.The liability for infringe-ment of intelligent unmanned aerial vehicles should strictly follow the operator's responsibility path.The reason for the liability of intelligent unmanned aerial vehicle operators should be transformed from"dan-gerous liability doctrine"to"compensation liability doctrine",and its application will be unified with the current aviation law infringement liability system to avoid the unreasonable allocation of legal risks in the application of technology,which will inhibit the technological innovation of artificial intelligence applied in aircraft.
