I know QNH refers to the altimeter setting. However, is it an acronym? And if so...for what? If not, what is the significance of these three letters. Thanks.

I looked for about 20 minutes but couldn't find the old ICAO Q Codes. Perhaps you could start with this link from Oz.

I'm not old enough to remember it's common use in aviation, but I have seen an ICAO Convention with a couple of hundred aviation-related Q Codes, such as the QNH you've asked about. Maybe someone else has a good link.

Briefly, they date back to old radio practice, and Morse Code. Surely there are some (other) hams here to go down that road!

Best Regards,

Buff

I don't think QNH stands for anything. It's just a code to indicate altimeter settings.

BTW, here's another link on Q-codes that includes an explanation of QNH.

As far as I can remember, the Q codes as they were known, herald from the war days when it was easier to say QNH, QFE & QNE rather than the full phrase. Even in writing it would be quite a mouthful, just imagine what it would be like on the radio.

I think the Q codes were used because in the old days they used morse code so it was faster to type QNH in morse code than writing the whole phrase to ask what is the altimeter setting?
That is what I was told once but I don´t know if it is true.
Can anyone confirm this theory?
Thanks
Archie
