Αεροπορία, or “aeronautics” in English, refers to the study, design, and operation of flight-capable machines, particularly airplanes and helicopters. It encompasses various aspects including the principles of flight, the science of aviation technology, and the navigation and management of aircraft in the air. The term can also refer to the military branch responsible for aerial warfare and operations, which is known as air force in many countries. In a broader sense, aeronautics involves the integration of engineering, physics, and environmental science to enhance air travel, improve safety, and develop new aviation technologies.
