In: AIAA Aviation 2022 Forum, 27 June - 1 July 2022 Chicago, IL, Article number AIAA 2022-3619https://doi.org/10.2514/6.2022-3619https://dspace.lib.cranfield.ac.uk/handle/1826/18155This paper investigates a quantitative ground risk assessment method for future urban airmobility, which can be divided into three main processes: risk modelling, risk assessment andmitigation recommendation for flight planning and management. First, the aircraft kineticmodels for both fixed-wing aircraft and rotorcraft are investigated, along with the correspondingballistic and glide descent mode and the associated wind influence. The probabilistic impact toroad traffic and pedestrians on the ground as a result of potential crash are then derived. Withan assumed crash probability of the aircraft, the initial risk value and distribution are computed,which are used to produce a risk cost map across the mission area. Next, the flight request isprocessed based on such risk map using a common path planning algorithm, minimizing theoverall risk for the flight plan to be generated. Finally, a preliminary case study involving arotorcraft conducting urban cargo transportation service is performed to evaluate the proposedrisk assessment method in a real-world urban environment.enAttribution-NonCommercial 4.0 Internationalhttp://creativecommons.org/licenses/by-nc/4.0/Air Transportation SystemsConference paper978-1-62410-635-4
