FAA Part 107 is a set of regulations established by the Federal Aviation Administration that governs the operation of small unmanned aircraft systems (UAS), commonly known as drones, for commercial purposes. It outlines the requirements for drone pilots, including age, certification, and operational limitations, ensuring safety in the national airspace. Under Part 107, drone operators must obtain a Remote Pilot Certificate by passing a knowledge test. The regulations also specify guidelines for flying drones, such as maintaining visual line of sight, flying below 400 feet, and avoiding restricted airspace. These rules help promote safe and responsible drone use in various industries.
