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 He requested that the FAA Eastern Region's letter of interpretation be rescinded.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.

Continuing significant orders to the training market shows that Piper Aircraft is making progress in its three-year plan to gain market share in that competitive arena.
L-3 Aviation Products plans to join the general aviation ADS-B world with its Lynx MultiLink Surveillance System. The new products will be “specifically tailored to fit the panel and budget of today’s general aviation aircraft and pilots,” said Larry Riddle, vice president of sales and marketing.
It was a big day for the newly resurrected Mooney International Corp. Mooney president Jerry Chen handed over the keys to the first airplane to roll out of the Kerrville, Texas, manufacturer’s newly reactivated factory site.
