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.
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).
Strictly speaking a flight level is an indication of pressure, not of altitude. Only above the transition level (which depends on the local QNH but is typically 4000 feet above sea level) are flight levels used to indicate altitude; below the transition level feet are used. e.g. FL250 = 25,000 feet above mean sea level when the pressure at sea ...
The flight levels correspond to the altitude in 100-ft increments (hectofeet) above the pressure surface of 1,013.25 hPa calculated according to the standard atmosphere. For example, FL050 is the pressure surface 5,000 ft above the pressure surface 1,013.25 hPa.
6 paź 2023 · Considering the severe consequences of getting it wrong, understanding pressure altitude is critical to your flight’s safety. In this article, we’ll explain what pressure altitude is, how to calculate and use it, and how it fits in with the other types of altitude, like density altitude.
26 cze 2024 · Standard ISA temperatures within the troposphere are 23.3°F (-4.8°C) at Flight Level (FL) 100, -12.3°F (-24.6°C) at FL200, and -49.9°F (-44.4°C) at FL300. At altitudes above FL360, temperature remains constant. Pressure on average will decrease by nearly half for each 18,000 feet of altitude.
