The "science of flight in aircraft" refers to the study of the principles and mechanics behind how airplanes fly. Synonyms for this phrase could include "aeronautical science," "aviation science," or "flight technology." These terms all encompass the same core concept of understanding how aircraft are designed, engineered, and operated to achieve controlled flight. Within this field, researchers may study topics such as aerodynamics, propulsion systems, aviation safety, and air traffic control. By deepening our knowledge of the science of flight, we can continue to innovate and improve air travel for the future.
