Understanding Altitude references - FlyByWire Simulations
QNH is the most used reference in airline operations, and several airlines prohibit flying using a QFE reference. QFE is the setting of the altimeter so that it will read the height above the airport that you are landing or departing from.

Altimeter Setting - AviationHunt
Oct 9, 2024 · QNH: This setting adjusts the altimeter to read the altitude above mean sea level (MSL). It is the most commonly used setting and is essential for ensuring that all aircraft in a given area are using the same reference point for altitude.
QNH is given in hectopascals in a four figure group, e.g.1008, or 0998. QNH values are preceded by the letter Q. QNH values in METAR/SPECI are rounded down to the whole hectopascal. TAF3 -the inclusion of TAF3, following the forecast QNH readings in the RMK section of the TAF, indicates the presence of a TAF3 service. It may

Mar 8, 2023 · QNH refers to the altimeter setting so that an aircraft's altitude above MSL (Mean Sea Level) is indicated. This setting is used during departure and approach and requires the pilot to set the local pressure at MSL. It is provided in the ATIS information and by ATC.
QNH - FlightGear wiki
QNH is a brevity code for "atmospheric pressure at sea-level". It is needed when starting or landing an aircraft, when it is important to have the indicated altitude as accurate as possible. Uses

Dec 26, 2020 · QNH (“Height Above Sea Level”) - QNH is a pressure setting you dial into your altimeter to produce the height above sea level. It reads runway elevation when you are on the runway and is based on an altimeter setting adjusted until the station's correct elevation above sea level is read.
QNH, QNE, and QFE: Altimeter Settings and Their Critical Role in …
Apr 15, 2020 · QNH: Your altitude above mean sea level. QNE: Your altitude standardized to 1013.25 hPa. QFE: Your altitude relative to the local airfield pressure. Let’s summarize all; QNH is a pressure value and when an aircraft sets it on the altimeter while on the runway. It will show the ELEVATION of the threshold above mean sea level.
Altimeter setting - Wikipedia
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.
