In aviation and aviation meteorology, a flight level ( FL) is an aircraft's altitude at standard air pressure, expressed in hundreds of feet.
The Flight Level is written using the two letters FL with the altitude (at standard QNH) in feet, without the two digits at the end: 10000 feet becomes Flight Level 100 = FL100; 6500 feet becomes Flight Level 65 = FL65; Commonly, the standard altimeter setting is used worldwide at or above the transition level (TL). ¶ ISOBARIC SURFACE CURVE
13 cze 2020 · Flight Level is measured in imperial feet. Standard Metric Level is measured in metric meters. Either, whether represented in feet or meters, is the distance at which an aircraft flies above the atmospheric level of standard pressure (Pressure Altitude).
14 wrz 2023 · Flight Level. Flight level is a type of altitude used in aviation above a certain altitude, typically 18,000 feet above mean sea level. It is the altitude above the standard datum plane in 100-foot increments. Pilots use flight level instead of true altitude to reduce the number of altitude corrections required for atmospheric pressure changes.
6 paź 2023 · Definition of Indicated Altitude: Indicated altitude is the altitude reading shown on your aircraft’s altimeter. It is an extrapolated estimation of your elevation above sea level and is corrected for atmospheric conditions.
FL180 and FL300 stand for Flight Level 180 and Fight Level 300. Flight levels are spaced 100ft apart on an altimeter that is set to the standard sea level pressure (QNE) of 1013.25 hectopascals or 29.92 inches of Mercury. So indeed, FL300 means 30,000 ft.
Flight Level (FL) A surface of constant atmosphere pressure which is related to a specific pressure datum, 1013.2hPa, and is separated from other such surfaces by specific pressure intervals. Altitude above sea-level in 100 feet units measured according to a standard atmosphere.
