What regulation did the Civil Aeronautics Act of 1938 introduce?

The Civil Aeronautics Act of 1938 was a significant piece of legislation that laid the groundwork for the regulation of civil aviation in the United States. By establishing the authority for civil aviation regulation, the Act created the Civil Aeronautics Authority, which was responsible for overseeing airline safety, economic regulation, and the development of airways. This marked a crucial shift in how civil aviation was managed, moving from a more laissez-faire approach to one where the federal government had a direct role in ensuring the safety and efficiency of air travel.

The other options pertain to various aspects of aviation but do not directly relate to the primary impact of the Civil Aeronautics Act of 1938. While the Act indirectly influenced aspects like air traffic control and manufacturing standards over time, the primary purpose of the regulation was to establish a comprehensive framework for the federal oversight of civil aviation. Therefore, the assertion that it established the authority for civil aviation regulation is fundamentally accurate and aligns with the Act's significant historical importance.
