Question

Is carburetor throttle ice more likely to occur at a higher or lower power setting? Why?

Answer 1

Carburetor throttle ice is more likely to occur at a lower power setting due to reduced airflow and lower temperatures.

Step-by-step explanation:

Carburetor throttle ice is more likely to occur at a lower power setting.

When the throttle is set to a lower position, the airflow through the carburetor is reduced. This reduction in airflow can result in the temperature of the fuel-air mixture dropping below the freezing point, causing the formation of ice.

At higher power settings, the increased airflow provides more heat and prevents the formation of ice.
