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.).

Altimeter Setting
| Altimeter Setting | | | The barometric pressure at a given location corrected to mean (average) sea level. | | source: FAA Aviation Maintenance Technician Airframe Handbook (FAA-H-8083-31) |
| | | The value to which the scale of a pressure altimeter is set so as to read true altitude at field elevation. | | source: FAA Aviation Weather for Pilots (AC 00-6A) |
| | | The station pressure (barometric pressure at the location the reading is taken) which has been corrected for the height of the station above sea level. | | source: FAA Balloon Flying Handbook (FAA-H-8083-11) |
| | | The pressure datum in millibars or inches of mercury set on the altimeter subscale. | | source: FAA Flight Navigator's Handbook (FAA-H-8083-18) |
| | | The barometric pressure reading used to adjust a pressure altimeter for variations in existing atmospheric pressure or to the standard altimeter setting (29.92). | | source: FAA Pilot/Controller Glossary |
| | | Station pressure (the barometric pressure at the location the reading is taken) which has been corrected for the height of the station above sea level. | | source: FAA Pilot's Handbook of Aeronautical Knowledge (FAA-H-8083-25A) |
| | | The barometric pressure reading used to adjust a pressure altimeter for variations in existing atmospheric pressure or to the standard altimeter setting (29.92 inches of mercury, 1013.2 hectopascals or 1013.2 millibars). | | source: ICAO Aviation Chart Glossary |
| | | standard pressure altitude with reference to sea level (QNH) or local pressure altitude at the airport elevation (QFE) set by the crew on their altimeter and critical, especially during descent and approach: The altimeter setting is 1023. Confirm. | | source: ICAO English Pro Aviation Glossary |
| | | A correction of the station pressure to sea level used by aviation. This correction takes into account the standard variation of pressure with height and the influence of temperature variation with height on the pressure. The temperatures used correspond to the standard atmosphere temperatures between the surface and sea level. | | source: NOAA National Weather Service Glossary |
