Aeronautical science encompasses the practical aspects of aviation and aeronautics. Jobs in this field focus on all aspects of the aviation industry. If you have a background in aeronautical science, you have a technical knowledge related to the design and operation of aircraft, the practices governing air safety, and navigation equipment and techniques. Pilots and flight instructors operate aircraft to transport passengers or cargo or teach aspiring pilots how to fly planes. Air traffic controllers manage airplanes during takeoff and landing, and ensure that flying aircraft remain a safe distance apart. Flight engineers design aircraft to meet design and safety requirements and regulatory standards. They may also oversee the production of planes. Aeronautical scientists perform research related to aviation, air safety, and plane design. Aircraft mechanics monitor and repair different types of aircraft.
