  2. Altimeter setting - Wikipedia

    en.wikipedia.org/wiki/Altimeter_setting

    QFE - is the barometric altimeter setting that causes an altimeter to read zero when at the reference datum of a particular airfield (in practice, the reference datum is either an airfield center or a runway threshold). In ISA temperature conditions the altimeter will read the height above the airfield/runway in the vicinity of the airfield.

  3. QFF - Wikipedia

    en.wikipedia.org/wiki/QFF

    QFF is the location value plotted on surface synoptic chart and is closer to reality than QNH, though it is only indirectly used in aviation. [citation needed] Another method [which?]: The derivation assumes that an isothermal layer at the station temperature extends to the sea level.

  5. Flight level - Wikipedia

    en.wikipedia.org/wiki/Flight_level

    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 and times. Therefore, by using a standard pressure setting, every aircraft has the same altimeter setting, and vertical clearance can be maintained during cruise flight. [1]

  6. Height above ground level - Wikipedia

    en.wikipedia.org/wiki/Height_above_ground_level

    The altimeter, which is usually a barometer calibrated in units of distance instead of atmospheric pressure, can therefore be set in such a way as to indicate the height of the aircraft above ground. This is done by communicating with the control tower of the airport (to get the current surface pressure) and setting the altimeter so as to read ...

    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).
