What Is Aeronautics? Aeronautics is the science that underlies the study, design, and manufacture of airplanes or other aviation vehicles. Aeronautics also includes research into methods for aircraft operation within the earth's atmosphere. Aeronautical engineers apply principles and concepts of engineering to create new aircraft containing the most current and sophisticated technologies.
Aeronautical Engineering was the original term for the field but as flight technology advanced to include craft operating in outer space, the broader term  aerospace engineering has largely replaced it in common usage.
