WebStrictly 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 ... WebRelationship Between Altitude and Pressure The following table and graph illustrate the relationship between altitude and pressure using the default values for pressure and …

WebThe altitude is the vertical distance of an object from mean sea level measured by means of a distance measuring instrument (for example a laser distance finder or a radar altimeter). The flight level is a vertical standard “pressure altitude” also called nominal altitude expressed in hecto-feet (hundreds of feet). For example, a pressure ... WebJan 19, 2024 · P 0 P_0 P 0 is the pressure at the reference level h 0 h_0 h 0 . In our pressure calculator, it is assumed that the reference level is located as sea level, so h 0 = 0 h_0 = 0 h 0 = 0. T T T is the temperature at altitude h h h, expressed in Kelvins. The temperature at altitude calculator may help you find it. g g g is the acceleration due to ... WebThe average pressure at mean sea level (MSL) in the International Standard Atmosphere (ISA) is 1013.25 hPa, or 1 atmosphere (atm), or 29.92 inches of mercury.
