Hi,

They don't use any of the Q codes in the US. QNH is one of the few
still in use around the rest of the world, the rest are pretty
much archaich. You stil occasionally hear QFE in the UK, but no
airlines I know of are using it anymore since modern airplanes
aren't designed around their use (QFE settings on the altimeter
**** up the computers since the computer is anticipating a QHN
setting to run a bunch of other devices in the airplane, of which
pressurisation is the most relevant) Very occasionally you hear
QSY which is "see you, I'm going to talk to someone else" and QDM
almost never nowadays, but it used to be relatively common and
it's Mag direction to a station. And even less used QDR which is
the Mag radial from a station. I think the Maritime world might
use a lot more of them still, though.

The UK PPL syllabus still teaches QNH, QFE (the military use it
here, and some civil airfields will give it in the initial
response). QDM, QDR and QTE (true bearing) are also taught. QDM is
on the R/T 'practical' test generally.

But, like sticking to imperial measurements, I think you stand alone.
Britain is still clinging to a number of archaic aviation terms (you
still gotta know which direction to go whatever you choose to call
it!) One of my favorites is the "Pan" call. Nobody uses that anymore
except you guys. I had an entertaining few minutes in Germany
listening to some Nigel making one of these a few years back. It went
something like this. The Nigel Skipper is played Terry Thomas and the
German controller by Hardy Kruger in this re-creation.

Boffo Air 2234 "Rhine, Boffo 2234, PAN PAN PAN"
ATC "Station calling?"
BA 2234 "Rhine this is Boffo 2234, PAN PAN PAN"
ATC. "Boffo 2234, pass your message"
BA 2234 "Rhine, this is Boffo 2234, PAN PAN PAN"
ATC, "Boffo 2234, say again?"
BA2234 "Rhine, this is a PAN call from Boffo 2234"
(at this point you can almost hear the Boffo skiper thinking "bloody
foreigners"
ATC, "Boffo 2234, are you declaring an emergency?"
BA2234 "Negative Rhine, Boffo 2234 is making a PAN call"
ATC, -silence-
BA 2234, Rhine, we have a pasenger having a heart attack, we're
mkaing a PAN call"
ATC, "Boffo 2234, do you wish to declare an emergency?"
BA 2234 "Nega- Oh, yes, yes, we're declaring an emergency, we'd like
to divert to Frankfurt immediatly. "
ATC, roger 2234, fly heading 330 and descend now to FL 150"

No ****, this really happened. I think it actually took longer than
this. The Brit captain just wouldn't let go....

I'm not sure but I think it was Thomas Cook.

Nice. It reminds me of this funny commercial:

Co-incidentaqlly, they showed that very commercial at my CRM refresher
last week!

ICAO Annex 10, Volume 2, part 5.2, Distress Communications.
The rules come from ITU Radio Regulations.

It's part 5.3. And the phrase "mayday relay" is *not* defined there.
It's always dangerous to cite a source without having actually read it.

There are several differences between maritime and aviation radio
procedures. One is that the expression "mayday ralay" is not used in
aviation. Another example is that in aviation you say "stop
transmitting" rather than the maritime "silence". Let alone the maritime
procedure to get a clearance for climbing to FL200...
