Title: Explain the effects of carburetor heat.
Course: Aircraft Pilot Training I (20053-I) > Section: Understanding Aircraft Systems: Engines

Explanation should include the following concepts:

- Carburetor heat can be used to melt ice that has already formed in the carburetor if the accumulation is not too great, but using carburetor heat as a preventative measure is the better option.
- Carburetor heat may also be used as an alternate air source if the intake filter clogs, such as in sudden or unexpected airframe icing conditions. The carburetor heat should be checked during the engine run-up.
