- The definition of aviation means the science of developing and flying airplanes.
Creating a blueprint for a new plane and flying an airplane are both examples of activities in the field of aviation.
- the art or science of flying airplanes
- the development and operation of heavier-than-air craft, including airplanes and piloted or guided rocket ships
- aircraft, esp. military aircraft, collectively
Origin of aviationFrench ; from Classical Latin avis, bird
- The operation of aircraft.
- The design, development, and production of aircraft.
- Military aircraft.
Origin of aviationFrench, from Latin avis, bird; see awi- in Indo-European roots.
