Check this out...especially the last paragraph. It is the Introduction to
the AIM:

"...The Aeronautical Information Manual will not contain informative items
concerning everyday circumstances that pilots should, either by good
practices or regulation, expect to encounter or avoid."

Sure--as I explicitly pointed out earlier in the thread, it would often (but
not always) be careless and reckless to fly a non-icing-certified plane in
foreceast icing conditions, even if they're not *known* icing conditions
(under the AIM's current definition). So yes, there are many times when a
pilot should avoid forecast icing conditions, even if no specific regulation
requires that avoidance, and even if the AIM doesn't explicitly say so. But
that doesn't bear on what we've been discussing, does it?

I subscribe to the Summit Aviation CD-ROM that contains just about every
piece of paper issued by the FAA, regularly updated, and as I look at the
list of changes to the AIM I do not find 7-1-22 (used to be 7-1-23) listed
anywhere. Admittedly, there is a lag between when the FAA does something
and when Summit publishes it.

Bob, the current definitions (in 7-1-23) are on the FAA's web site:
http://www.faa.gov/atpubs/aim/Chap7/aim0701.html#7-1-23.
To verify that the definitions are new, just look in any pre-2005 copy of
the AIM, or else just Google "FAA AIM changes 7-1-23" and look at the cached
(no longer online) copy of "AIM Change 2" (2nd search result).
