Preliminary ground risk tiering for small unmanned aerial vehicles (sUAV) in metropolitan environments

Unmanned aircraft systems (UAS) are anticipated to increase in the future and be employed for a variety of applications such as parcel delivery, structural inspections, aerial photography, and surveillance. However, the growth of the UAS industry is impeded by delayed operational approvals and risk...
