Which federal entities regulate flight and ground instruction?

The Federal Aviation Administration (FAA) is the primary regulatory body for all aspects of civil aviation in the United States, including flight and ground instruction. The FAA establishes and enforces regulations that govern aviation operations, safety standards, and the certification of flight schools and instructors. This includes ensuring that flight instructors meet specific training and qualification standards, which are critical for maintaining a high level of safety in aviation education.

The FAA's role encompasses a broad range of responsibilities, from issuing pilot licenses to overseeing air traffic control and managing the nation's airspace system. Their involvement is essential to ensure that flight instruction adheres to the established guidelines and safety protocols necessary for effective training.

While the other federal entities mentioned play important roles in the transportation sector, they do not specifically regulate flight and ground instruction. The Federal Trade Commission (FTC) primarily focuses on consumer protection and competition issues, the National Transportation Safety Board (NTSB) investigates transportation accidents but does not regulate instruction, and the Department of Transportation (DOT) oversees broader transportation policies and agencies but does not specifically handle the certification and regulation of flight instruction. Thus, the FAA is the correct answer regarding the regulation of flight and ground instruction.
