QNH?
What does QNH stand for... i know it means the sea level pressure but is it an acronym for something? http://www.pprune.org/ubb/NonCGI/cool.gif
ANyone know? ------------------ "..there's really nothing like a shorn scrotum. It's breathtaking, I suggest you try it" |
All part of the old morse Q code

I did hear someone say the 'Q' was for Question
QFE would then be: 'Question Field Elevation' However, the one who told me this didn't know what QNH could be.... |
Not forgetting our old friend 'QRB'. Any takers?

Q Code:
It was all to keep the beastly Germans from knowing wot we wuz on about. ;) Among other discussions hereabouts, try: www.pprune.org/ubb/NonCGI/Forum3/HTML/000300.html ------------------ -.-- --.- -..- [email protected] |
It is an old misconception that the "Q" stood for "Question". Ever since people have tried, with some success in some cases and less in others, to complete the "acronyms" in the Q-code. Some operators may well have tried to make acronyms of them to make them easier to remember, but this was not the way they were designed.
It is also a nonsense that it was wartime code. Even in the realms of the most jingoistic war film, the Germans' codebreaking was just a tad better than that. It was simply a method of abbreviating frequently-used messages to make it simpler and faster to send by morse. Anything more than that is pure fantasising. |
Question - Nil Height

The 'Q' was definitely not for question. The interrogative function was 'IMI' , transmitted as one symbol. The 'code' was simply a form of abbreviation since much communication was in Morse code and it helped to speed things up. Perhaps the classic illustration was one of the 'Qs' (long since forgotten) which meant something like -"Will you shine your searchlight on the clouds, occulting if possible, in order to ascertain the cloudbase and pointing in the direction of the prevailing wind or main swell direction" !!! QZR (or whatever it was) was a lot easier on the fingers :)

Someone told me once that it stood for the Queen. But i guess there was a king when these came about so go figure...?

QRB is, does I understand, stand for Quick Release Box. This is a device used to connect a helicopter winchman's bosun's chair to the winch wire. If he becomes snagged in rigging, for example he can punch it to release himself from the cable rapidly. Anyway, it seems to me there are too many TLA's in this business as it is......... Dinky doo!.............. |
I am being interfered with??????
Oo-Er...don't know if that was QRB, but there was certainly a q-code for it. Anyone remember what it was? |
QRM = "Are you being interfered with/I am being interfered with".
QRB as "Quick release box" is not a Q-code. The meaning within the Q-code is "How far are you from my station?/The distance between our stations is .... nm". |
If i m not wrong, Q stands for pressure in Latin and so QNH = pressure at nil height.
"Shut your mouth. Know your role." |
I was told the NH stood for Nautical Height, & FE for Field Elevation. Seems reasonable to me.
|
According to the 'Combined Operating Signals' manual, 1946, QRB as a question means 'at what approximate distance are you from my station?' There's a useless bit of information. Oops, sorry Huggy.
