An ongoing discussion about carb heat and proper usage brought up a question. One poster mentioned a 20-year-old copy of an AOPA Air Safety Foundation Safety Report that showed but one accident attributed to carb ice in the thirty year period reviewed.
Is more recent data available, without having to dig through the Nall Report looking for it? Any analysis available on carb ice accidents? I know of one, the plane I trained in about three years after I finished up. Wondered how many others there are, frequency, severity, etc.
Associated question: what's a good number on the Carb Heat Gage when using partial carb heat? Actually, what number to activate at, and what number to raise to. Mine has an orange stripe from -10 to +10°C. Others have Carb Heat on engine monitors, but no such stripe there. I pull enough in IMC to stay above the stripe; don't recall ever seeing it below the stripe, but flying VFR in WV, I didn't pay it much attention. Often had OATs around -10°C.
Thanks, ya'll!
