Which system is most associated with carburetor or induction icing?

• A. Fuel/air induction system.
• B. Electrical system.
• C. Hydraulic system.
• D. Propeller system.

Answer: (A)

Carburetor and induction icing happens in the fuel/air induction system. When moist air passes through the carburetor or intake, the rapid pressure drop and fuel vaporization cool the air-fuel mixture. If the air is humid, this cooling can cause ice to form in the carburetor throat or intake passages, restricting airflow and causing a drop in engine power. The way to deal with it is carburetor heat, which brings in warmer air from around the exhaust to melt the ice and restore proper airflow. The electrical, hydraulic, and propeller systems aren’t where this icing originates or is primarily addressed, so the association is clearly with the fuel/air induction path.
