These five multiple choice questions will test how well you understand the phenomenon of carburetor icing. Once you've taken the quiz be sure to check out our Carburetor Icing Probability Calculator, or for a more deep dive into the mechanics of aircraft carburetors take a look at our article on a Technical Overview of the Aircraft Carburetor.

1. In what atmospheric conditions is the risk of carburetor icing greatest?

2. What is the primary mechanism by which ice forms in the carburetor venturi?

3. Air moving through a venturi behaves in a way described by Bernoulli’s equation. Which statement is true?

4. How does the application of the carburetor heat lever mitigate icing?

5. Why does the application of carb heating result in a slight drop in engine power?
