Does anybody have a good handle on when ATC wants you to read back
altimeter settings? On a single IFR flight on Tuesday, I encountered
several controllers who I'd check in with, and they'd give me an altimeter
setting, and that would be it, and 2 (both in Canada, BTW) whom when I
didn't read back the altimeter setting gave it to me again.


In the US I've never read back an altimeter, I've rarely heard anyone
else do it, and I've never heard anyone questioned for it.

In the UK it is mandatory and they will prompt you if you don't read
it back. I guess Canada operates to the same procedures as the UK.

US radio practice is actually quite a bit different from the
international norm, as you quickly discover when you try to fly
somewhere else!
