  2. Altimeter setting - Wikipedia

    en.wikipedia.org/wiki/Altimeter_setting

    QNH - is the barometric altimeter setting that causes an altimeter to read aircraft elevation above mean sea level - altitude (AMSL - above mean sea level) in ISA temperature conditions in the vicinity of the airfield that reported the QNH value. QFE - is the barometric altimeter setting that causes an altimeter to read zero when at the ...

    Altimeter reading when subscale set 1013.25 hPa (atmospheric pressure at sea level in the International Standard Atmosphere) [2] QNH: The pressure set on the subscale of the altimeter so that the instrument indicates its height above sea level (the altimeter will read runway elevation when the aircraft is on the runway). [1] Request Leeds QNH

  4. Pressure altitude - Wikipedia

    en.wikipedia.org/wiki/Pressure_altitude

    It indicates altitude obtained when an altimeter is set to an agreed baseline pressure under certain circumstances in which the aircraft’s altimeter would be unable to give a useful altitude readout. Examples would be landing at a high altitude or near sea level under conditions of exceptionally high air pressure.

  5. Flight level - Wikipedia

    en.wikipedia.org/wiki/Flight_level

    In aviation, a flight level (FL) is an aircraft's altitude as determined by a pressure altimeter using the International Standard Atmosphere. It is expressed in hundreds of feet or metres. The altimeter setting used is the ISA sea level pressure of 1013 hPa or (29.92 inHg). The actual surface pressure will vary from this at different locations ...

    The following AWOS configurations are defined below in terms of what parameters they measure: [6] AWOS A: barometric pressure and altimeter setting (in inches of Mercury ). AWOS I: wind speed and wind gusts (in knots ), wind direction (from which the wind is blowing) and variable wind direction (in degrees of the compass ), temperature and dew ...

  9. Pressure altimeter - Wikipedia

    en.wikipedia.org/wiki/Pressure_altimeter

    The greater the altitude, the lower the pressure. When a barometer is supplied with a nonlinear calibration so as to indicate altitude, the instrument is a type of altimeter called a pressure altimeter or barometric altimeter. A pressure altimeter is the altimeter found in most aircraft, and skydivers use wrist-mounted versions for similar ...
