Welcome to the Dauntless Aviation Glossary!
At Dauntless, our editorial staff maintains the web's largest unified glossary of aviation terms. This glossary is built from a combination of official, quasi-official,
and proprietary sources (including original material that we develop oursselves). Uniquely, we often provide multiple definitions of a given term so that you can find that which best applies
to you. In order to maximize your learning efficiency, this glossary (and similar ones for our international users) is incresingly fully integrated into our aviation learning apps, including
our FAA written test prep and FAA practical test prep software and apps. If you like this glossary,
you'll love them with their polished learning environments and world's best and clearest content (please do give them a try.).

Free Air:
Free Air: | | Refers to the undisturbed air flowing past an aircraft. Free air flowing over an aircraft in flight causes lift and drag on aerodynamic surfaces on an aircraft. Stabilizing surfaces on an aircraft are intended to react in lift and drag according to the free air flow over the aircraft in order to compensate for the free air reactions of the aircraft or aircraft components. Another component of the airflow over a stabilizing surface may be the accelerated air in the propwash of the propeller. | source: Glossary of Gyroplane Terms |
