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.).

Stall
| Stall | | - Sudden loss of lift when the angle of attack increases to a point where the flow of air breaks away from a wing or airfoil, causing it to drop.
- A maneuver initiated by the steep raising of an aircraft's nose, resulting in a loss of velocity and an abrupt drop.
| | source: FAA Aerosense Glossary |
| | | A rapid decrease in lift caused by the separation of airflow from the wing’s surface brought on by exceeding the critical angle of attack. A stall can occur at any pitch attitude or airspeed. | | source: FAA Airplane Flying Handbook (FAA-H-8083-3A) |
| | | A flight condition in which an angle of attack is reached at which the air ceases to flow smoothly over the upper surface of an airfoil. The air becomes turbulent and lift is lost. | | source: FAA Aviation Maintenance Technician Airframe Handbook (FAA-H-8083-31) |
| | | Condition that occurs when the critical angle of attack is reached and exceeded. Airflow begins to separate from the top of the wing, leading to a loss of lift. A stall can occur at any pitch attitude or airspeed. | | source: FAA Glider Flying Handbook (FAA-H-8083-13A) |
| | | A rapid decrease in lift caused by the separation of airflow from the wing’s surface, brought on by exceeding the critical angle of attack. A stall can occur at any pitch attitude or airspeed. | | source: FAA Risk Management Handbook (FAA-H-8083-2) |
| | An airplane is stalled when the angle of attack is beyond the stalling angle. A stall is characterized by any of, or a combination of, the following: - Buffeting, which could be heavy at times.
- A lack of pitch authority.
- A lack of roll control.
- Inability to arrest descent rate.

| | | A rapid decrease in lift caused by the separation of airflow from the wing's surface brought on by exceeding the critical angle of attack. A stall can occur at any pitch attitude or airspeed. | | source: FAA Weight Shift Control Handbook (FAA-H-8083-5) |
| | | a sudden breakdown of fluid flow around the aerofoil (wing) or in an engine: stall can result in the aircraft losing stability and lift and in engine failure | | source: ICAO English Pro Aviation Glossary |
