  caused by induction system icing. Induction system icing is an operating hazard because it can cut off the flow of the air-fuel charge or vary the air-fuel ratio. Ice can form in the induction system while an aircraft ... system icing is generally classified in three types: • Impact ice, • Fuel evaporation ice, and • Throttle ice. Induction system ice can be prevented or eliminated by raising the temperature of the air that passes through the system, using a carburetor heat…

  exhaust systems also serve as a heat source for the cabin and carburetor. The risks of operating an aircraft with a defective exhaust heating system include carbon monoxide poisoning, a decrease in engine performance, and an increased ... potential for fire. Because of these risks, technicians should be aware of the rate of exhaust heating system deterioration and should thoroughly inspect all areas of the exhaust heating system to look for deficiencies inside and out. Combustion Heater Systems…

  also fail to show shortcomings, since the allowable rpm dropoff is only a measure of an improperly functioning ignition system and is not necessarily affected by other factors. Conversely, it is possible for the magneto check to prove satisfactory when ... below: 1. Control position check. 2. Cowl flaps (if equipped)—open. 3. Mixture—rich. 4. Propeller—high rpm. 5. Carburetor heat—cold. 6. Check propeller according to propeller manufacturer’s instruction. 7. Open throttle to the run-up rpm setting…
