6 maj 2017 · An aircraft flying in the flight levels will be flying reference pressure altitude; and aircraft below the transition level should be flying reference indicated altitude using a QNH or local altimeter setting.
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.
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.

14 wrz 2023 · Pressure altitude is indicated when an altimeter is set to a standard atmospheric pressure of 29.92 inches of mercury (inHg) or 1013.25 millibars (MB). It determines an aircraft’s height above a standard datum plane rather than above mean sea level.
