Title: Describe anti-icing and de-icing systems.
Course: Aircraft Pilot Training II (20053-II) > Section: Operating the Aircraft

Description should include the following:

- Carburetor ice occurs due to the effect of fuel vaporization and the decrease in air pressure in the venturi, which causes a sharp temperature drop in the carburetor.
- 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.
