A new interpretation of what "known icing conditions" really means could ground general aviation aircraft for the winter. But AOPA is not going to let that happen.
The new interpretation, handed down from the FAA's Eastern Region counsel, says that "high relative humidity" constitutes known icing conditions. This means that in high relative humidity conditions when the temperature is near or below freezing, pilots must fly an aircraft with deicing equipment. Many light GA aircraft aren't equipped for flight into known icing conditions.
"This overly restrictive interpretation of 'known icing conditions,' if literally applied, would unnecessarily ground many safe general aviation flights and may negatively affect safety because many pilots would not be able to train nor maintain flying proficiency during the winter season," wrote Luis Gutierrez, AOPA director of regulatory and certification policy, in a letter to the FAA. He requested that the FAA Eastern Region's letter of interpretation be rescinded.
AOPA pointed out that this restrictive interpretation is not consistent with other FAA publications, including the Aeronautical Information Manual, which state that visible moisture, along with freezing temperatures, is necessary for structural icing in flight. High relative humidity is not visible.
The association further explained that relative humidity is not included in FAA or National Weather Service aviation weather reports or forecasts.
"So how are pilots to know when high relative humidity would be a factor to their flight," Gutierrez challenged the FAA, "and how are pilots expected to know what constitutes high relative humidity since this is not defined anywhere?"
The FAA's previous definition of known icing conditions was objective, quantified, and based on meteorology, Gutierrez explained. AOPA believes this new definition - which could shut down an entire segment of the GA industry - is subjective, is not scientifically proven, and should not be accepted.

As the cold weather chills AOPA’s Headquarters in Frederick, many of us are inside generating new resources for flying clubs.
In my house, every Friday night is “Movie Night.” While the movies are rarely educational (I don’t think I learned anything from the Lego Movie), we look forward to the weekly opportunity to spend time together. Why not use the same concept for your Flying Club (with the addition of education, of course)?
AOPA Flying Club Manager Kelby Ferwerda posted the following on the AOPA Flying Club Facebook Page: “Recently I’ve talked with quite a few Flying Clubs about maintaining social activity through the cold winter months. Some clubs host Holliday Parties, others have Potluck Movie Nights. What does your club do to keep members involved during the chilly months?”
