51. PLT190
Which condition is most favorable to the development of carburetor icing?
A) Any temperature below freezing and a relative humidity of less than 50 percent.
B) Temperature between 32 and 50 °F and low humidity.
C) Temperature between 20 and 70 °F and high humidity.

52. PLT249
While cruising at 9,500 feet MSL, the fuel/air mixture is properly adjusted. What will occur if a
descent to 4,500 feet MSL is made without readjusting the mixture?
A) The fuel/air mixture may become excessively lean.
B) There will be more fuel in the cylinders than is needed for normal combustion, and the excess
fuel will absorb heat and cool the engine.
C) The excessively rich mixture will create higher cylinder head temperatures and may cause
detonation.
和訳 : Mixtureについて
53. PLT189
Generally speaking, the use of carburetor heat tends to
A) decrease engine performance.
B) increase engine performance.
C) have no effect on engine performance.

54. PLT190
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
A) a drop in oil temperature and cylinder head temperature.
B) engine roughness.
C) loss of RPM.

55. PLT189
Applying carburetor heat will
A) result in more air going through the carburetor.
B) enrich the fuel/air mixture.
C) not affect the fuel/air mixture.

56. PLT253
On aircraft equipped with fuel pumps, when is the auxiliary electric driven pump used?
A) All the time to aid the engine-driven fuel pump.
B) In the event engine-driven fuel pump fails.
C) Constantly except in starting the engine.
和訳と解説
57. PLT250
If the grade of fuel used in an aircraft engine is lower than specified for the engine, it will most likely
cause
A) a mixture of fuel and air that is not uniform in all cylinders.
B) lower cylinder head temperatures.
C) detonation.
58. PLT478
One purpose of the dual ignition system on an aircraft engine is to provide for
A) improved engine performance.
B) uniform heat distribution.
C) balanced cylinder head pressure.
59. PLT115
Detonation occurs in a reciprocating aircraft engine when
A) the spark plugs are fouled or shorted out or the wiring is defective.
B) hot spots in the combustion chamber ignite the fuel/air mixture in advance of normal ignition.
C) the unburned charge in the cylinders explodes instead of burning normally.
60. PLT115
If a pilot suspects that the engine (with a fixed-pitch propeller) is detonating during climb-out after
takeoff, the initial corrective action to take would be to
A) lean the mixture.
B) lower the nose slightly to increase airspeed.
C) apply carburetor heat.
