Which agency regulates UAS operations in the United States?

The Federal Aviation Administration (FAA) is the agency responsible for regulating unmanned aircraft systems (UAS) operations in the United States. The FAA's primary role is to ensure the safety and efficiency of the National Airspace System (NAS). This includes setting rules and regulations for the operation of both manned and unmanned aircraft, establishing guidelines for pilot certification, airspace management, and UAS registration requirements.

The FAA's authority allows it to develop and enforce regulations specific to UAS, addressing various aspects such as operational limits, airspace restrictions, and safety standards. Their comprehensive regulations help integrate UAS operations into the existing aviation framework while minimizing potential risks to other air traffic and ensuring public safety.

Other agencies, like the Department of Transportation, NASA, and the FBI, may have roles in broader transportation or aviation-related activities, but they do not specifically regulate UAS operations in the way that the FAA does.
