Aero-Terms!
Aero-Terms are designed to be a daily reminder of the terms,
names, acronyms and explanations of the unique language that
populates the aviation world. Aerospace, sport aviation, fixed
wing, helo, you name it... it's all fair game.
Aero-Terms should serve as a quick but intriguing reminder of
the terms you may use every day, or an introduction to an aspects
of the Aero-World you may not yet be familiar with. ANN also
encourages readers to go beyond the FMI link, and further research
any intriguing terms.
Suggestions for future Aero-Terms are ALWAYS
welcome, as are additions or discussion of the
explanations given for each Aero-Term.
QNH
QNH is a Q code. It is a pressure setting used by pilots, air
traffic control (ATC) and low frequency weather beacons to refer to
the barometric altimeter setting which will cause the altimeter to
read altitude above mean sea level within a certain defined region.
This region may be fairly widespread, or apply only to the airfield
for which the QNH was given. An airfield QNH will cause the
altimeter to read field elevation on landing irrespective of the
temperature. In the UK the lowest forecast value of QNH for an
altimeter setting region is called the "Regional Pressure Setting"
and may be used to ensure safe terrain separation when cruising at
lower altitudes. In some parts of the world a similar procedure is
adopted and this is known as "Regional QNH" however this name has
been modified to the above in the UK for reasons of ambiguity.
