Final answer:
A 33lb small UAS used for real estate imagery is subject to 14 CFR part 107, which sets forth the regulations for commercial drone operation, including certification and privacy concerns.
Step-by-step explanation:
The operation of a 33lb small UAS (Unmanned Aircraft System) for capturing aerial imagery over real estate for sales listings is indeed subject to 14 CFR part 107. 14 CFR part 107 outlines the rules and regulations for the operation of small unmanned aircraft systems in the National Airspace System. Since the UAS in question is for commercial purposes (real estate sales listings), it must adhere to these regulations, which include requirements for the remote pilot certification, registration of the UAS, and operational limitations. It is important to be well-versed in, and compliant with, these regulations to ensure the legality and safety of UAS operations.
The privacy issues associated with drone usage, related to the potential for them to monitor private property without detection, highlight significant concerns for society. Applying the Fourth Amendment protections in the context of modern technology like UAS is a complicated issue as it was written in a time before such advanced surveillance capabilities. The UAS operator should remain aware of privacy laws as well as the risk of infringing upon the rights of individuals when conducting surveillance or capturing imagery.
