The QNH altimeter setting is one of the data included in METAR messages. An alternative setting is QFE or SPS/STD: An alternative setting is QFE or SPS/STD: 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 ...
QNE is an aeronautical code Q code.The term refers to the indicated altitude at the landing runway threshold when or is set in the altimeter's Kollsman window. It is the pressure altitude at the landing runway threshold.
In aviation terminology, the regional or local air pressure at mean sea level (MSL) is called the QNH or "altimeter setting", and the pressure that will calibrate the altimeter to show the height above ground at a given airfield is called the QFE of the field. An altimeter cannot, however, be adjusted for variations in air temperature.
QFE: The pressure set on the subscale of the altimeter so that the instrument indicates its height above the reference elevation being used [e.g. aerodrome elevation] [1] Runway in use 22 Left, QFE 990 hectopascals QFF: Atmospheric pressure at a place, reduced to MSL using the actual temperature at the time of observation as the mean ...

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?
