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.).

Wind Shear
Wind Shear | | A sudden, drastic shift in windspeed, direction, or both that may occur in the horizontal or vertical plane. | source: FAA Airplane Flying Handbook (FAA-H-8083-3A) |
| | A strong and sudden shift in wind speed or direction, which may be either vertical or horizontal. Wind shear should not be confused with normal wind change, which is gentler. Wind shear is often associated with the passage of a weather front, or a strong temperature inversion. | source: FAA Balloon Flying Handbook (FAA-H-8083-11) |
| | A change in wind speed and/or wind direction in a short distance resulting in a tearing or shearing effect. It can exist in a horizontal or vertical direction and occasionally in both. | source: FAA Pilot/Controller Glossary |
| | A change in wind speed and/or wind direction in a short distance. | source: FAA Pilot's Handbook of Aeronautical Knowledge (FAA-H-8083-25A) |
| | A sudden, drastic shift in wind speed, direction, or both that may occur in the horizontal or vertical plane. | source: FAA Weight Shift Control Handbook (FAA-H-8083-5) |
| | The rate at which wind velocity changes from point to point in a given direction (as, vertically). The shear can be speed shear (where speed changes between the two points, but not direction), direction shear (where direction changes between the two points, but not speed) or a combination of the two. | source: NOAA National Weather Service Glossary |
