the meaning of the initials qnh

[BrendAn]

does anyone really know what qnh stands for.   we all know qnh is the pressure setting on an altimeter but it seems impossible to find the actual meaning of the letters.  i found one explanation that is question nil height,  another that says q is the morse code for question but doesn't give a clue to what the n and h are.

[Roundsounds]

QNH is part of an aeronautical code covering QAA - QNZ. Similar Q codes are used in military and nautical functions. 
 

Here’s a link for your reference. 

[Ironpot]

UK Military always taught that QNH is Q “Newlyn Harbour”.
( Newlyn Harbour is where zero sea level is calculated from for the UK based on the observations taken there for many years)

QFE is Q Field Elevation

That might be a "LOCAL" use thing.  Nev

Not quite.  It’s Nauntical Height

 

in practice it’s the current pressure at MSL which allows your instruments to do exactly what you expect - tell you a height relative to sea level you can compare to maps etc which are given with elevation relative to MSL

I have a question at Nil Height 

[Jabiru7252]

It goes back to the days when reports were sent via morse code and teletype. The 'Q' code made things easier to send...

[old man emu]

I remember an article in the, then, Dept of Civil Aviation Safety Digest entitled "QNH Queer Notion of Height?". The theme was the danger of buzzing people, especially on arrival or departure from private farm strips. 

[Old Koreelah]

A similar, but unrelated acronym VKG was traditionally used to signify Police HQ radio. 
We were told it originally meant Voice of King George.

[turboplanner]

What is the meaning of QNH?

It is one of the Q Codes developed for Morse Code acronyms in the early 20^th century, that all start with “Q” denoting a question.

 

QNH stands for Question Nil Height (Sea Level)

 

It’s a measurement of atmospheric pressure, so it falls into MET (Meteorology) training, which usually starts before Navigation Exercises start.

 

QNH is the Atmospheric Pressure at sea level.

QNH is normally obtains from ATIC at major airfields.

When the QNH is set on the altimeter sub scale it will show the height above sea level.

If you’re at a small country strip and you know the altitude of the strip, you can adjust the sub scale until the altitude is correct and read the QNH in the Kollsman window.

 

Area QNH is used on cross country flying and in Australia is defined as airspace for which area QNH forecasts are prepared. Zones, boundaries are found on Airservices Australia’s Planning Chart (PCA).

 

That usually equates to a new Met station every 100 Nm, so on a four hour cross country flight you’ll usually be re-setting your QNH about four times during the flight, hence the benefit of doing a Flight Plan using the correct charts before you leave.

 

 

QAA to QNZ were allocated for aeronautical use.

QOA to QNZ were allocated for maritime use.

QRA to QUZ were allocated for all services.

A similar, but unrelated acronym VKG was traditionally used to signify Police HQ radio. 

VKG was the radio callsign for New South Wales Police. It wa issued by the Postmaster General Department. 

 

The VK part is the international code for Australia from 1 January 1929. I think Victoria Police was VKC. Ham operators were VK and a number which indicated their State.

The "Q" code is related to the use of morse code. I think telegrams were sent that way, but that was by wire.. I've not heard of it being used in Civil Aviation outside of QNH, QFE, QNE all related to Altimetry in Aviation. Demonstrated ability in transmitting and receiving in Morse Code was required in Commercial Aviation as late as the 60's.  Nev

On this Morse code thing, one of the things that always scared me about even starting to learn how to fly when I was young was that apparently you had to learn it, and I thought that seemed impossible. I was pleasantly surprised when I did decide to learn to fly that you didn't have to know anything about Morse code anymore 😄

How did you identify the Nav Aids?    Nev

The morse sent from the navaids was so slow you didn't need to know the code. A good pilot would simply have a cheat sheet, listen to the code (da da     da di di dit     dah di dah dah -  that's MBY). I learnt morse to get my Ham Radio Licence and never used morse since. Note how morse is 'spoken' Dits and Dahs not dots and dashes.
