In aviation and aviation meteorology, a flight level ( FL) is an aircraft's altitude at standard air pressure, expressed in hundreds of feet.
Flight is an American television anthology series that originally aired in syndication from 1958 to 1959. The series originally aired for one season, with 38 half-hour episodes produced.
Un niveau de vol est exprimé en centaines de pieds, et précédé du sigle FL (de l'anglais flight level, « niveau de vol »). Ainsi une altitude de 30 000 pieds (9 144 m) avec un calage de 1 013,25 hPa est notée FL 300.
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.
Poziom lotu ( ang. Flight level) – powierzchnia baryczna o określonym ciśnieniu oddzielona od innych takich powierzchni o określoną różnicę ciśnienia i odniesiona do specyficznej wartości ciśnienia zwanego ciśnieniem standardowym o wartości 1013,25 hPa (760 mm Hg).
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.
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.”.
