                                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.
