Well, I KNEW this was a can of worms. The thread has been very
enlightening. Thanks.

I did check with FSS one time, when I was getting a weather briefing, to
clarify the legality of operations in forecast icing. He would not
touch my question with a ten-foot pole. He essentially refused to
answer. Now I see why. The article's at avweb, cited in this thread,
make it clear that FAA and NTSB are at odds over icing rules.

At the risk of re-starting a fire...does the generic line in weather
reports saying that there is "generally the possibility of icing above
the freezing level in clouds and perecipitation" mean that icing is
ALWAYS forecast above the freezing level (assuming there are some clouds
above the freezing level)? Or does that generic line not really count
as a forecast?

I KNOW this is a big can of worms, but I have a specific question
relating to sub-paragraphs b.1 and b.2 of this regulation regarinding
operating in icing conditions.

It says "...no pilot may fly--
(1) Under IFR into konwn or forecast moderate icing conditions; or
(2) Under VFR into known light or moderate icing conditions..."

This seems odd. Why do you suppose the standards are different for IFR
and VFR ("moderate" vs "light or moderate)? Icing affects a pilots
ability to control the aircraft, so I do not see how instrument training
allows one to venture into worse conditions.

So, if there is an airmet for "light icing", then it is legal for an IFR
pilot to enter the clouds (of course, on a valid IFR flight plan)?

What perectnage of the time, during winter, do icing forecasts get
issued whenever there are IFR conditions? In other words, in y'alls
experience, if you get 100 briefings during the winter time that include
IFR conditions, what perecntage of those will also have icing forecast.
My intuition says that it will be upwards of 90-100% (I am a relatively
new IFR pilot, so I do not have the experience base to say...looking for
other opinions here). If it is close to 100%, should I just hang up my
IFR certificate from Sept to May (I live in Wisconsin, so we only have
about 30 minutes of summer here per year ).
