4 dni temu · To calculate the air pressure at a certain altitude, use this simple formula: P = P0 × exp(-g × M × (h - h0)/(R × T) where: P0 and h0 — The pressure and altitude of the reference point. Often, these values correspond to the ones at sea level. P — The pressure at altitude h. T — The temperature at altitude h.

The temperature at the bottom of the stratosphere is determined by subtracting 71.5 K from the temperature at sea level. Altitude is calculated from air pressure and vice versa. A detailed table and plot along with descriptions of the equations are included.

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.
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.
Flight Level specifically refers to Pressure Altitude in 100 foot increments within the Standard Pressure Region, which in North America starts at 18000 ft and above, and at various lower altitudes elsewhere.
In aviation and aviation meteorology, a flight level (FL) is an aircraft's altitude at standard air pressure, expressed in hundreds of feet. The air pressure is computed assuming an International Standard Atmosphere pressure of 1013.25 hPa (29.92 inHg ) at sea level , and therefore is not necessarily the same as the aircraft's actual altitude ...
