The field is closely related to astronautics, which deals with flight beyond Earth's atmosphere. In a broader sense, aeronautinen can refer to anything associated with flight, air travel, or the aviation industry. This includes everything from the engineering of airplanes and helicopters to air traffic control and the study of atmospheric phenomena relevant to flight. The Finnish word is commonly used in technical contexts and discussions about aviation.
