From page 9...
... Because of actions by regulators, manufacturers, and operators, the aviation system provides a transportation capability that has the lowest safety risk of any mode of motorized transportation. While accidents involving large commercial aircraft do occasionally happen, the rate of occurrence is so low that safety experts no longer focus on corrective actions associated with accidents or incidents but are now focused on proactive safety initiatives based on analysis of precursors of potential accidents.

... that have the authority to designate their own aircraft as airworthy. For proponents planning to operate in compliance with either the model aircraft rule or the small UAS rule, no additional scrutiny or review by the FAA is required, and they have operational approval as long as they remain within the operational limits expressed in 14 CFR Part 101 and 14 CFR Part 107.

... As of September 2017, however, there has only been one confirmed collision between a UAS and a manned aircraft in the United States.9 Research using data from incident reports is ongoing. Key goals include quantifying how unique hazards affect risk and methods for evaluating specific risks and how to mitigate them (FAA, 2017)

... • Beyond visual line-of-sight operation -- An operation in which the remote crew is not able to remain in visual contact with the aircraft to manage its flight and meet separation and collision avoidance responsibilities. • Comparative risk analysis -- Involves contrasting risks produced by two activities using a common scale.

... . With an autonomous system, the farmer might simply give a verbal command to survey the crops, and the UAS would identify the crops planted in the various fields, an optimum flight path, the parameters to monitor, and the range of acceptable values based on the crop, recent and forecast weather, where the crops are in their life cycle, past experience, and so on.
