QSY?

[RMurphy195]

So there I was, airband radio in hand, sitting up on the Lickeys listening to B'ham approach etc. to try and develop my R/T "Listening Ear".

Then I heard an unfamiliar term "QSY", associated with requests to/instructions to switch frequencies. But I can't find it in CAP413 , for my sins.

Am I missing something?

That's because it's no longer approved terminology

Most of the others on this list are seldom heard > http://www.pilotfriend.com/training/fli ... q_code.htm

QSY means changing frequency to another station (And is paradoxically often heard)

Aha - now I understand - so I guess despite it's common use, I should avoid it (don't want to get into bad habits!)

I hated it when it was approved terminology.

The phrase "change to your en-route frequency" is only slightly longer, much clearer, and utterly unambigious.

QSY is an awful lot easy to send as a five figure morse group though than its long hand counterpart

[KNT754G]

and it is a palindrome in morse

Not used anywhere else outside the UK as far as I know.
The FIS/approach controllers abroad seem to hand you off to the next sector where possible, so you don't need to worry about when or who to call next, or who's airspace you're about to bust.

It was used everywhere where morse was used for communications. It still is used worldwide by radio amateurs in morse (and very often in speech, too, by old lags like me). I can't offhand remember hearing it in aviation elsewhere than the UK, but I probably wouldn't have noticed it if I had.

I heard it for the first time last week on East Midlands Approach. An aircraft requested a frequency change and the controller responded with "QSY approved". It was only because of this thread that I understood what the controller meant.

QSY, sayonara.

[A le Ron]

It's very commonly used in the areas I fly (Yorkshire, Doncaster, Humberside, East Mids)

I like using QSY - as an old "ham" I miss Morse code and all the Q-code abbreviations

But I accept its unhelpful from a safety perspective and confusing for newcomers. But it all adds to the mystique..!
