2.13: Carburetor Icing

Question 1

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

Answer 1

more susceptible to icing.

Question 2

Which condition is most favorable to the development of carburetor icing?

Answer 2

Temperature between 20 degree F and 70 degree F and high humity.

Question 3

The possibility of carburetor icing exists even when the ambient temperature is as

Answer 3

high as 70 degree F and the relative humidity is high.

Question 4

If an aircraft is equipped with a fixed-pitch propeller and a float-type carburetor, the first indication of carburetor ice would most likely be

Answer 4

decrease of RPM.

Question 5

If an aircraft is equipped with a fixed-pitch propeller and a float-type carburetor, the first indication of carburetor ice would most likely be

Answer 5

loss of RPM.

Question 6

The operating principle of float-type carburetors is based on the

Answer 6

difference in air pressure at the venturi throat and the air inlet.

Question 7

The presence of carburetor ice in an aircraft equipped with a fixed-pitch propeller can be verified by applying carburetor heat and noting

Answer 7

a decrease in RPM and then a gradual increase in RPM.
