Over six months in the latter half of 2018, a research project was undertaken in support of Transportstyrelsen and their continuing activity in the regulation and oversight of UAV operations in Sweden. UAV operations are evolving as experience grows not solely for pleasure and personal use. As business opportunities are found and as the capabilities of UAVs are better understood so these shape emergent potential UAV use. The benefits of these, both new and current uses of UAVs, can provide significant benefits to society as well as business opportunities. Within the UAV community, Beyond Visual Line of Sight operations (BVLOS) are perceived as a step change in UAV operational capability and an enabler to new classes of operational tasks. These hold significant potential for society as a whole as well as for more effective ways for many activities, be they industrial, agricultural, communications or saving lives at sea and overland. In recognition of the need for Transportstyrelsen to facilitate the evolution and development of this step change, a need to better understand the nature of risk assessment for Beyond Visual Line of Sight operations was identified. Additionally, the potential need for a risk assessment method with which to undertake risk assessments was also recognised. Linköping Universitet (LiU)in collaboration with Lunds Universitet (LU) were contracted for six months to carry out a small-scale research project to investigate UAV risk assessments and to identify a risk assessment method that is suitable for Transportstyrelsen to use in the approval of Beyond Visual Line of Sight UAV applications.
