Confirm vs Verify

[Dazzler]

Is there any difference between "Confirm" and "Verify" or are they interchangable?

It has been my experience that controllers tend to us "Verify"
e.g. "Verify you have ATIS information Charlie"

and pilots tend to use "Confirm"
e.g. "Confirm Cessna 12345 is cleared to land on runway 28L"

Are these words synonymous?

"confirm" is not in the pilot/controller glossary.

That isn't the answer, unless you're flying in the UK. "Confirm" is non-standard phraseology in the US and so should be avoided.

Yup, I realize that now. I've heard "Confirm" being used in the US though, but now I know that it is non-standard.

I'm not sure what is "official" but I will tell you how I use them.

Say I issue you a clearance to cross a fix @ 10'000. Your 10 miles from the fix and have yet to descend... I state Verify you are crossing XXX @ 10K

Confirm I use for something I am trying to figure out, say I want to make sure you have the proper arrival route. I will say confirm routing to destination or something to that affect. I guess they are interchangeable, I have never really thought about it.

I know that is probably not the answer you are looking for ...
