What should a pilot do if they suspect carburetor ice has formed?

When a pilot suspects that carburetor ice has formed, the appropriate and most effective action to take is to apply carburetor heat. Carburetor ice typically forms when moisture in the air freezes within the carburetor, disrupting the proper fuel-air mixture and potentially leading to engine performance issues or even a loss of power.

Applying carburetor heat warms the air entering the carburetor by routing it through a heated duct, which helps to melt any ice that has formed. This allows the engine to function properly as it restores the correct fuel-air mixture. It is crucial to apply the carburetor heat as soon as ice formation is suspected, especially during conditions conducive to icing, such as humid air at low temperatures.

While reducing throttle might temporarily reduce the engine load and might help alleviate some symptoms, it does not address the root cause of carburetor ice and might lead to further complications. Increasing altitude would not rectify the ice problem and could potentially exacerbate the situation, especially at lower temperatures. Switching fuel type is not a practical solution to carburetor ice, as it does not eliminate the existing ice or prevent its formation in the carburetor.
