In regards to the spirit of the thread...... I have made a personal choice never to fly my un-equipped aircraft intentinally into visible precipitation when the temp is close to freezing or below. That obviously limits my winter GA flying. However, I was trying to gain a technical/legal understanding of what is or is not legal in the eyes of the FAA regarding unequipped aircaft flying in known/forecast icing conditions.


I obviously understand you can't legally fly into known icing conditions. One of my problems is I cant nail down a definition of known icing conditions. I realized just now as Im typing perhaps my hangup rests in bowersbum's post. The NTSB has in some cases to the best of my knowledge used, the AIM 7-1-21 (b) (im using an 08 version so that might be the difference between browersbum's AIM (7-1-22 b) to define known icing conditions. If that is true I would have to be prudent and just use the more restrictive definition. Which would compliment my decision to not fly in cold clouds/visible precip.
