Does a dual check of the VORs for use in instrument flight only count if it

We had a fairly heated hanger discussion about this and I would like to hear
some more opinions.

How do the airborne advocates read "while airborne" into the regulation?
The implicit requirement is that the station be received with a good
ident and no waving off flag. Granted, that would usually require you
be airborne, but certainly not always.
