Which entity is primarily responsible for enforcing airport operational standards?

The Federal Aviation Administration (FAA) is primarily responsible for enforcing airport operational standards. This governmental body sets regulations that govern all aspects of civil aviation in the United States, including ensuring that airports adhere to safety and operational protocols. The FAA establishes guidelines that airports must follow to maintain safety and efficiency, and it conducts inspections and audits to ensure compliance.

This role is crucial as airports must operate within the regulatory framework established by the FAA to secure the safety of air travel and ensure standardization across the aviation industry. The FAA's regulatory power extends to aspects such as air traffic control, runway safety, and facility management, thus making it the key authority in enforcing operational standards at airports.
