Peter,

have been trying hard to establish the 396 v 496 difference, for
European use where there is no airborne weather. Unfortunately none of
the vendors I spoke to seems to know anything about it (they aren't
pilots, for a start).


Didn't we speak about this extensively? You didn't give the impression
that you were still lacking any information. If so, ask away.
