Which organization is responsible for regulating civil aviation in the United States?

The Federal Aviation Administration (FAA) is the primary organization responsible for regulating civil aviation in the United States. This agency oversees all aspects of civil aviation, including the development of safety regulations, the certification of personnel and aircraft, and the management of air traffic. The FAA's mission is to ensure safe and efficient air travel within U.S. jurisdiction, which encompasses everything from airport operations to pilot licensing.

The FAA's authority also extends to coordinating with other countries on international aviation standards, which is critical for maintaining global air safety and interoperability. Through comprehensive policies and regulatory frameworks, the FAA plays a vital role in maintaining the safety of the aviation infrastructure and the overall airspace system in the United States.
