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.

Carburetor icing can occur in outside air temperatures up to 28°C (82°F) with high humidity, making it a constant threat to pilots of carbureted aircraft. Knowing how to know when to use carb heat is a critical skill for preventing engine trouble and ensuring flight safety, especially during descents and low-power operations.
