In aviation and aviation meteorology, a flight level (FL) is an aircraft's altitude at standard air pressure, expressed in hundreds of feet.
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). This is based on the principle of something called the International Standard Atmosphere.
A Flight Level (FL) is the vertical distance of an aircraft above the ISOBARIC SURFACE of 1013.25hPa (hecto Pascal) or 29.92 in Hg (inches of Mercury). An ISOBARIC SURFACE is the invisible landscape that connects all points with the same atmospheric pressure.
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 Level is a standard altitude measurement system used in aviation. Unlike altitude, which is measured from the ground level, Flight Level is established based on a standard pressure reference, allowing for consistent altitude navigation regardless of atmospheric conditions.
10 mar 2024 · Flight Levels (FL): Here’s the definition of a Flight Level by the ICAO (International Civil Aviation Organization): “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.”.
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.
