2008-09　Private Pilot Knowｌedge (Private Written) Exam 米国自家用操縦士筆記試験

61. PLT478
The uncontrolled firing of the fuel/air charge in advance of normal spark ignition is known as
A) combustion.
B) pre-ignition.
C) detonation.

62. PLT343
What should be the first action after starting an aircraft engine?
A) Adjust for proper RPM and check for desired indications on the engine gauges.
B) Place the magneto or ignition switch momentarily in the OFF position to check for proper grounding.
C) Test each brake and the parking brake.

63. PLT343
If the engine oil temperature and cylinder head temperature gauges have exceeded their normal operating range, the pilot may have been operating with
A) the mixture set too rich.
B) higher-than-normal oil pressure.
C) too much power and with the mixture set too lean.

64. PLT253
During the run-up at a high-elevation airport, a pilot notes a slight engine roughness that is not affected by the magneto check but grows worse during the carburetor heat check. Under these circumstances, what would be the most logical initial action?
A) Check the results obtained with a leaner setting of the mixture.
B) Taxi back to the flight line for a maintenance check.
C) Reduce manifold pressure to control detonation.

65. PLT249
The basic purpose of adjusting the fuel/air mixture at altitude is to
A) decrease the amount of fuel in the mixture in order to compensate for increased air density.
B) decrease the fuel flow in order to compensate for decreased air density.
C) increase the amount of fuel in the mixture to compensate for the decrease in pressure and density of the air.

66. PLT324
An abnormally high engine oil temperature indication may be caused by
A) the oil level being too low.
B) operating with a too high viscosity oil.
C) operating with an excessively rich mixture.

67. PLT351
A precaution for the operation of an engine equipped with a constant-speed propeller is to
A) avoid high RPM settings with high manifold pressure.
B) avoid high manifold pressure settings with low RPM.
C) always use a rich mixture with high RPM settings.

68. PLT351
What effect does high density altitude, as compared to low density altitude, have on propeller efficiency and why?
A) Efficiency is increased due to less friction on the propeller blades.
B) Efficiency is reduced because the propeller exerts less force at high density altitudes than at low density altitudes.
C) Efficiency is reduced due to the increased force of the propeller in the thinner air.

69. PLT196
Automatic Terminal Information Service (ATIS) is the continuous broadcast of recorded information concerning
A) pilots of radar-identified aircraft whose aircraft is in dangerous proximity to terrain or to an obstruction.
B) nonessential information to reduce frequency congestion.
C) noncontrol information in selected high-activity terminal areas.

70. PLT140
When should pilots decline a land and hold short (LAHSO) clearance?
A) Pilots can not decline clearance.
B) Only when the tower operator concurs.
C) When it will compromise safety.
