14 CFR Part 107 pertains to which of the following?

14 CFR Part 107 specifically deals with the regulation and operation of Small Unmanned Aircraft Systems (UAS), which are commonly known as drones. This part of the Federal Aviation Regulations sets the framework for the commercial use of small drones within the national airspace, ensuring that their operation is safe, efficient, and integrated with manned aircraft operations.

Part 107 outlines various operational limitations and requirements, including the need for remote pilot certification, aircraft registration, and adherence to specific flight rules, such as altitude limitations and airspace restrictions. By establishing these guidelines, Part 107 helps regulate the use of drones for commercial purposes, addressing safety and integration with existing aviation practices.

The other choices relate to aviation aspects that do not accurately represent the focus of Part 107. For example, while pilots and air traffic control, passenger safety regulations, and commercial flight operations are essential components of aviation regulation, they are covered under different parts of the CFR, not specifically under Part 107, which is solely dedicated to drone operations.
