"Known Icing Conditions" The subject of flight into "known icing" or "known icing conditions" has fueled hangar flying sessions for decades. At long last we have a definition from the Office of the General Counsel. It is no longer an objective rule, giving pilots strict boundaries to adhere to, but is now more subjective...relying on what a "reasonable and prudent" pilot would do. Two things to remember: controllers are not ice police and don't care whether your plane is certificated for flight in the ice or not, and just saying the word "ice" will get you all kinds of help from the ATC system. Unless you have an accident, that's the last that you will hear about it. http://www.faa.gov/about/office_org/headquarters_offices/agc/pol_adjudication/agc200/interpretations/data/interps/2009/Bell.pdf
