Title: Describe factors that cause carburetor ice.
Course: Aircraft Pilot Training I (20053-I) > Section: Examining Aircraft Instruments, Components, Systems, and Performance

Description should include the following:

- If water vapor in the air condenses when the carburetor temperature is at or below freezing, ice may form on internal surfaces of the carburetor, including the throttle valve. This restricts the flow of the fuel-air mixture and reduces power.
- If enough ice builds up, the engine may cease to operate.
