In aviation and aviation meteorology, a flight level ( FL) is an aircraft's altitude at standard air pressure, expressed in hundreds of feet.
Flight levels use QNE or pressure altitude, while altitude references QNH or local pressure adjusted to sea level pressure. Altitudes are used at low levels and flight levels at higher levels. The transition between altitudes and flight levels differs by country and is generally just above the highest obstacle in that country.
25 sty 2024 · A flight level (FL) is a standard pressure altitude, expressed as three numbers. Aircraft flying on flight levels all measure their altitude from the same pressure setting, 1013.2 Hpa (or 29.92 InHg).
14 wrz 2023 · What is Flight Level in Aviation? Flight level is a type of altitude used in aviation that is defined as the altitude above the standard datum plane in 100-foot increments. It is typically used above a certain altitude, such as 18,000 feet above mean sea level.
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.
Flight Levels (FL) are "officially designated" pressure altitudes at or above the official transition altitude (TA). These TA and FL designations are different by country, or even within different terminal areas of the same country.
To avoid mid-air collisions, aircraft fly at predefined altitudes known as flight levels. These flight levels are dependent on the atmospheric pressure and vary according to the weather conditions. Aircraft must always be separated by a certain distance to avoid mid-air collisions as they fly.
