If carburetor heat is applied and no icing is present, what happens? :: The mixture becomes richer. What happens in some aircraft if the induction air filter becomes blocked? :: The system automatically allows warm, unfiltered air into the engine. What should an operator do if an induction fire starts during engine starting? :: Continue cranking the engine. What effect does carburetor heat have on the mixture? :: The mixture becomes richer. What does an increase in RPM or manifold pressure after applying carburetor heat indicate? :: Ice was forming in the carburetor. In what position should the carburetor heat control be during engine starting? :: Cold or Off. Is carburetor heated air filtered? :: No. What can result from using carburetor heat when it is not needed? :: Decrease in power and possible detonation. What part of an aircraft will usually accumulate ice first in flight? :: Carburetor. How may carburetor icing be eliminated? :: Alcohol spray and heated induction air.
