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.).

Angle of Attack
| Angle of Attack | | | The acute angle at which a moving airfoil meets the airstream. | | source: FAA Aerosense Glossary |
| | | Angle of Attack (AoA): The acute angle between the chord line of the airfoil and the direction of the relative wind. | | source: FAA Airplane Flying Handbook (FAA-H-8083-3A) |
| | | The acute angle formed between the chord line of an airfoil and the direction of the air that strikes the airfoil. | | source: FAA Aviation Maintenance Technician Airframe Handbook (FAA-H-8083-31) |
| | | The acute angle between the chord line of a propeller blade and the relative wind. The angle of attack is affected by both the engine rpm and the forward speed of the aircraft. | | source: FAA Aviation Maintenance Technician Powerplant Handbook (FAA-H-8083-32) |
| | | The angle formed between the relative wind and the chord line of the wing. | | source: FAA Glider Flying Handbook (FAA-H-8083-13A) |
| | | The angle between the airfoil’s chord line and the relative wind. | | source: FAA Helicopter Flying Handbook (FAA-H-8083-21A) |
| | | The acute angle formed between the chord line of an airfoil and the direction of the air striking the airfoil. | | source: FAA Pilot's Handbook of Aeronautical Knowledge (FAA-H-8083-25A) |
| | | Angle of attack is the angle between the oncoming air or relative wind, and some reference line on the airplane or wing. | | source: FAA Upset Recovery Training |
| | | Angle of attack (AOA): The acute angle between the chord line of the airfoil and the direction of the relative wind. | | source: FAA Weight Shift Control Handbook (FAA-H-8083-5) |
| | | AOA or á: the angle between the chord line of the wing of an aircraft and the vector representing the relative motion between the aircraft and the atmosphere. Information from the angle of attack sensor, or alpha probe, is used to trigger a stall warning. | | source: ICAO English Pro Aviation Glossary |
