The Federal Aviation Administration (FAA) is the agency responsible for the regulation of airport operations in the United States. The FAA oversees the safety and efficiency of the nation's air traffic system, which includes establishing regulations that govern airport design, operations, and maintenance. It plays a critical role in ensuring that airports comply with federal safety standards, thus maintaining a safe flying environment for passengers and cargo.

Additionally, the FAA is responsible for the certification of airports and the oversight of air traffic control, which are essential operational facets of successful airport management. Its regulations encompass various aspects, such as operational limits, safety procedures, and infrastructure requirements, ensuring that all operations meet a consistent level of safety and efficiency across the nation’s airports. This regulatory framework is fundamental in promoting safe air travel and preventing accidents, thereby underscoring the FAA's pivotal role in the aviation sector.
