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).
With Standard Pressure (1013.2 mb) set, an aircraft altimeter indicates Pressure Altitude (Flight Level), and is used by all aircraft operating above the transition altitude to provide a common datum for vertical measurement.
30 gru 2012 · Say you know the aircraft altitude and the cabin altitude and you want to figure out the delta p: Read from the aircraft altitude (column 1) to the psia (column 4), and then read from the cabin altitude (column 1) to the psia (column 4) and subtract the two numbers. So if you are flying along at 40,000 the pressure (standard day) is about 2.71 psi.
the cleared flight level by 90 m (300 ft) or more, the controller should ask the pilot to check the altimeter setting and to confirm the aircraft’s present flight level.
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 and standard pressure. 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.
Above sea level, the calibrated airspeed must be re-scaled for pressure effects on compressibility. The mathematical method for determining \(V_e\) from \(V_c\) is to first solve the calibrated airspeed equation for \(q_c\) .
