Operation Volume Determination for Small Unmanned Aircraft Systems Based on Specific Operation Risk Assessment

The small Unmanned Aircraft Systems (sUAS) with Beyond Visual Line of Sight (BVLOS) have already been used for commercial operation in urban, which triggered the new operation risk. At present, the Specific Operation Risk Assessment (SORA) method has widely adopt by the competent authorization, but the acceptable means of compliance (AMC) are not sufficient to support the implementation of SORA. Overall, the determination of operational volume (OV) is one of the most urgent problems. In this paper, we firstly supposed the OV geography and summarized the possible operation scenarios. Then the determination method was proposed based on the key influencing factors. Finally, an urban logistical operation case with large amount of practical data was selected to verify the method. The results were analyzed and demonstrated the method was available.
