What is one responsibility of the Aeronautics Branch created by the Air Commerce Act?

The responsibility of issuing pilot licenses falls under the purview of the Aeronautics Branch established by the Air Commerce Act. This act, passed in 1926, was a significant step in regulating civil aviation in the United States. One of its key objectives was to ensure the safety and regulation of air travel, which included the certification and licensing of pilots to maintain standards within the aviation industry. By issuing pilot licenses, the Aeronautics Branch helped to establish a framework for aviators that ensured they met specific qualifications and complied with safety regulations, thereby promoting safer air travel. In contrast, other responsibilities mentioned, such as establishing airport rules or collecting airport taxes, would fall under different aspects of aviation regulation and governance.
