What regulations apply to UAS operations over unprotected persons?

When operating Unmanned Aircraft Systems (UAS) over unprotected persons, the primary regulation is that UAS operations must not pose a risk or hazard to individuals who are not in a protected area or who may be exposed to the operations. This means that pilots must ensure that their flights are conducted in a manner that prioritizes the safety and well-being of people on the ground. The regulations require remote pilots to assess the risks involved in their operations and take necessary precautions to avoid any potential harm.

Understanding the concept of "unprotected persons" is crucial here; these are individuals who are not shielded from the potential hazards associated with UAS operations. Thus, minimizing risk is a fundamental responsibility of a remote pilot.

In contrast, while some of the other options touch on safety, they do not accurately reflect the key regulatory concern when it comes to operating over unprotected persons. For instance, the statement about operations needing to occur only during the day is not universally applicable, as night operations can be conducted under specific conditions. The requirement to maintain a distance of 500 feet is not a blanket regulation and can vary based on the type of operation and local regulations. Lastly, the mention of flying only above 1500 feet is not relevant, as
