Induction icing
As has been the case on previous occasions, SNS3Guppy has made an erroneous statement and then denied having done so. In his post (#4) Guppy says: Quote "Piston engines utilize an alternate air door for the engine in lieu of carburetor heat, as there's no carburetor to heat" Unquote. I am sure Guppy simply forgot to type the word "Injected" at the start of the statement. However, as is his want, Guppy denies having made the statement and instead tells Dick Whittingham who questioned him, and later 411A, that they each have a comprehension problem.
Back to the original question. Yes, induction icing can take place in either a fuel injected engine or a conventional carburetor equipped engine. Induction icing can occur whenever the the metal inlet duct surface is at or below freezing point and super cooled moisture droplets impact the duct. Ice forms immediately in this case. It can also occur when the OAT is near or below freezing and the aircraft enters visible moisture (cloud, sleet, rain) such as when on descent from above the freezing level.
