Carburetor icing is most severe at - ANSWERS✔✔ air temperatures between 30 and 40*F.
Into what part of a reciprocating engine induction system is deicing alcohol normally
injected? - ANSWERS✔✔ The airstream ahead if the carburetor.
Carburetor icing on an engine equipped with a constant-speed propeller can be detected by
- ANSWERS✔✔ a decrease in manifold pressure with a constant RPM.
What part of an aircraft in flight will begin to accumulate ice before any other? -
ANSWERS✔✔ Carburetor.
Carburetor icing may be eliminated by which of the following methods? - ANSWERS✔✔
Alcohol spray and heated induction air.
Where would a carburetor air heater be located in a fuel injection system? - ANSWERS✔✔
None is required.
An increase in manifold pressure when carburetor heat is applied indicates - ANSWERS✔✔
ice was forming in the carburetor.
During full power output of an unsupercharged engine equipped with a float-type
carburetor, in which of the following areas will the highest pressure exist? - ANSWERS✔✔
Carburetor air scoop.
, The use of the carburetor are heater when it is not needed causes - ANSWERS✔✔ a
