Which of the following could be considered a violation of Part 107 regulations?

Flying without a valid remote pilot certificate is considered a violation of Part 107 regulations because this certification is required to ensure that UAV operators have the knowledge and skills necessary to safely operate unmanned aircraft systems. Part 107 establishes guidelines for commercial drone use, including the need for remote pilots to pass a comprehensive test that covers airspace rules, regulations, and operational safety.

Without a valid remote pilot certificate, an individual lacks the formal training and legal authority to operate drones commercially, which can lead to unsafe operations and risks to air traffic, people, and property on the ground. This requirement for certification is essential for maintaining safety and operational standards in the national airspace system.

In contrast, maintaining altitude in controlled airspace, reporting a malfunction, or operating below maximum weight limits adhere to safety regulations and do not constitute violations of Part 107. These actions show compliance and responsibility as a drone operator.
