History
Background
The
Air Commerce Act of May 20, 1926, is the cornerstone of the federal government's regulation of civil aviation. This landmark legislation was passed at the urging of the aviation industry, whose leaders believed the airplane could not reach its full commercial potential without federal action to improve and maintain safety standards. The Act charged the
Secretary of Commerce with fostering air commerce, issuing and enforcing air traffic rules,
licensing pilots, certifying aircraft, establishing airways, and operating and maintaining aids to air navigation. The newly created Aeronautics Branch, operating under the
Department of Commerce assumed primary responsibility for aviation oversight.
In fulfilling its civil aviation responsibilities, the
U.S. Department of Commerce initially concentrated on such functions as safety regulations and the certification of pilots and aircraft. It took over the building and operation of the nation's system of lighted airways, a task initiated by the
Post Office Department. The Department of Commerce improved aeronautical radio communications—before the founding of the
Federal Communications Commission
The Federal Communications Commission (FCC) is an independent agency of the United States federal government that regulates communications by radio, television, wire, satellite, and cable across the United States. The FCC maintains jurisd ...
in 1934, which handles most such matters today—and introduced radio beacons as an effective aid to air navigation.
The Aeronautics Branch was renamed the Bureau of Air Commerce in 1934 to reflect its enhanced status within the Department. As commercial flying increased, the Bureau encouraged a group of airlines to establish the first three centers for providing
air traffic control

(ATC) along the airways. In 1936, the Bureau itself took over the centers and began to expand the ATC system. The pioneer air traffic controllers used maps, blackboards, and mental calculations to ensure the safe separation of aircraft traveling along designated routes between cities.
In 1938, the
Civil Aeronautics Act
The Air Commerce Act of 1926 created an Aeronautic Branch of the United States Department of Commerce. Its functions included testing and licensing of pilots, certification of aircraft and investigation of accidents.
In 1934, the Aeronautics Branc ...
transferred the federal civil aviation responsibilities from the Commerce Department to a new independent agency, the
Civil Aeronautics Authority. The legislation also expanded the government's role by giving the CAA the authority and the power to regulate airline fares and to determine the routes that air carriers would serve.
President
Franklin D. Roosevelt split the authority into two agencies in 1940: the Civil Aeronautics Administration (CAA) and the
Civil Aeronautics Board (CAB). CAA was responsible for ATC, airman and aircraft certification, safety enforcement, and airway development. CAB was entrusted with safety regulation, accident investigation, and economic regulation of the airlines. The CAA was part of the Department of Commerce. The CAB was an independent federal agency.
On the eve of America's entry into
World War II

, CAA began to extend its ATC responsibilities to takeoff and landing operations at airports. This expanded role eventually became permanent after the war. The application of

to ATC helped controllers in their drive to keep abreast of the postwar boom in commercial air transportation. In 1946, meanwhile, Congress gave CAA the added task of administering the federal-aid airport program, the first peacetime program of financial assistance aimed exclusively at development of the nation's civil airports.
