What is the primary regulation governing UAS operations in the United States?

The primary regulation governing UAS (Unmanned Aircraft Systems) operations in the United States is found in 14 CFR Part 107. This regulation outlines the operational rules for small UAS, specifically those weighing less than 55 pounds. It includes guidelines on pilot certification, operational limitations, airspace restrictions, and procedures for remote pilots to follow to ensure safe and compliant operation of drones.

Part 107 is integral to defining how UAS can be used commercially and recreationally while maintaining safety in the national airspace system. The regulations established under Part 107 ensure that all remote pilots have received proper training and understand the necessary safety protocols, which is crucial given the increasing use of drones in various sectors such as agriculture, construction, and public safety.

Other options refer to different categories of aviation regulation. For instance, 14 CFR Part 101 pertains to the operation of unmanned free balloons and certain model aircraft and is not specific to UAS operations as defined in Part 107. Parts 121 and 135 focus on the operation of larger aircraft, primarily commercial airlines and commuter services, which are not applicable to the UAS framework.
