                                Carburetor icing is a constant threat to piston-engine aircraft, and it can occur in temperatures as high as 70°F with high humidity. Understanding what does the carb heat do is a fundamental skill for pilots to prevent this dangerous condition and ensure the reliable operation of their engine throughout a flight.
