A more thorough explanation:

Aviation refers to the operation of aircraft and the maintenance of aviation facilities. It is governed by both federal and state laws and regulations.

The United States Congress has enacted several federal laws pertaining to air navigation, including the 1926 Air Commerce Act, which provided for the certification and registration of aircraft employed in interstate or foreign commerce. The Civil Aeronautics Act of 1938 created the "Civil Aeronautics Authority," which regulated all aspects of aviation within federal jurisdiction. The Federal Aviation Act of 1958 established the Federal Aviation Administration, which further regulated aviation.

States are prohibited from regulating rates, routes, or services of any air carrier authorized under the Federal Aviation Act to provide interstate air transportation. However, states can enact their own laws consistent with federal laws or alter existing remedies under state law.

After the September 11, 2001 terrorist attacks, the Aviation and Transportation Security Act of 2001 established the Transportation Security Administration within the Department of Transportation to enhance aviation security.

Examples of aviation law include regulations on air traffic control, aircraft certification, and airport security. These laws ensure the safety and efficiency of air travel for passengers and cargo.
