With regard to carburetor ice, float-type carburetor systems in comparison to fuel injection systems are generally considered to be

A

more susceptible to icing.✓ Correct Answer

B

equally susceptible to icing.

C

less susceptible to icing.

Explanation

In a float-type carburetor, fuel vaporization and the pressure drop in the venturi can cool the air below freezing, so ice can form even at moderate outside air temperatures. A fuel injection system has no venturi and injects fuel at or near the intake ports, so PHAK Ch. 7 describes it as less susceptible to icing than a carburetor system. Therefore carburetors are more, not equally or less, susceptible to icing.
