The latest on known icing is a 2004 case...

In all my years of lecturing on icing and attending FAA icing conferences I
have never heard anyone, FAA or NWS, put forward the argument that you
espouse. It is bogus. Even before the 2004 case it was well established by
the NTSB (Administrator vs Bowen) that forecast conditions of moisture plus
below-freezing temps constitut known icing. You are late to the party, Gary.

I apologise in advance as this is a topic done to death in the past,
but I have heard various bits of info on this recently, some quoting
FAA or NTSB rulings etc, and others disputing that they are relevant
because there have been more recent events including a clarification
in the AIM.

I am in Europe but this is potentially relevant to me because I fly an
N-reg aircraft (not certified for any icing conditions).

What is the latest situation on this from the USA?

The current AIM (7-1-23) explicitly states that "forecast icing
conditions" are *not* "known icing conditions":

"Forecast Icing Conditions: Environmental conditions expected by a
National Weather Service or an FAA-approved weather provider to be
conducive to the formation of inflight icing on aircraft. "

"Known Icing Conditions: Atmospheric conditions in which the formation of
ice is observed or detected in flight."
