Which authority is responsible for regulating aeronautical engineering practices in the Philippines?

The Civil Aviation Authority of the Philippines (CAAP) is the correct authority responsible for regulating aeronautical engineering practices in the Philippines. This agency plays a crucial role in establishing safety standards, licensing aviation personnel, and overseeing the compliance of aviation operations with national and international regulations.

The CAAP ensures that all aeronautical engineering practices meet the safety and operational standards necessary to protect both passengers and crew. It manages air traffic and oversees the certification of aircraft, thereby directly impacting how aeronautical engineers design and maintain aircraft to ensure they are safe and efficient.

Other entities like the Department of Transportation have broader responsibilities, which include multiple modes of transportation but do not specialize specifically in aeronautics. The Philippine Air Force focuses on military aviation and defense rather than commercial or civil aeronautical practices. The National Aeronautics and Space Administration (NASA), based in the United States, is involved in space exploration and aeronautics research but does not regulate aeronautical practices in the Philippines.
