The pressure altitude corrected for nonstandard temperature

36
New cards

What is pressure altitude?

The altitude indicated when the barometric pressure scale is set to 29.92

37
New cards

Altimeter setting is the value to which the barometric pressure scale of the altimeter is set so the altimeter indicates

47
New cards

How do variations in temperature affect the altimeter?

Pressure levels are raised on warm days and the indicated altitude is lower than true altitude

48
New cards

A turn coordinator provides an indication of the

movement of the aircraft about the yaw and roll axes

49
New cards

To receive accurate indications during flight from a heading indicator, the instrument must be

periodically realigned with the magnetic compass as the gyro precesses

50
New cards

The proper adjustment to make on the attitude indicator during level flight is to align the

miniature airplane to the horizon bar

51
New cards

How should a pilot determine the direction of bank from an attitude indicator such as the one illustrated?

by the relationship of the miniature airplane to the deflected horizon bar

52
New cards

What is a benefit of flying with a glass cockpit?

Situational awareness is increased.

53
New cards

What steps must be taken when flying with glass cockpits to ensure safe flight?

Regularly scan both inside and outside, use all appropriate checklists, and cross-check with other forms of information

54
New cards

An aircraft which is equipped with an Electronic Flight Display (EFD) can

offer new capabilities and simplify the basic flying task

55
New cards

You are flying an aircraft equipped with an EFD and the air data computer fails. What instrument is affected?

Airspeed indicator

56
New cards

An abnormally high engine oil temperature indication may be caused by

the oil level being too low

57
New cards

Excessively high engine temperatures will

cause loss of power, excessive oil consumption, and possible permanent internal engine damage.

58
New cards

Excessively high engine temperatures, either in the air or on the ground, will

cause loss of power, excessive oil consumption, and possible permanent internal engine damage.

59
New cards

For internal cooling, air-cooled engines are especially dependent on

the circulation of lubricating oil

60
New cards

If the engine oil temperature and cylinder head temperature gauges have exceeded their normal operating range, the pilot may have been operating with

too much power and with the mixture set too lean

61
New cards

What action can a pilot take to aid in cooling an engine that is overheating during a climb?

Reduce rate of climb and increase airspeed

62
New cards

What is one procedure to aid in cooling an engine that is overheating?

enrich the fuel mixture

63
New cards

How is engine operation controlled on an engine equipped with a constant-speed propeller?

the throttle controls power output as registered on the manifold pressure gauge and the propeller control regulates engine RPM

64
New cards

A precaution for the operation of an engine equipped with a constant-speed propeller is to

avoid high manifold pressure settings with low RPM

65
New cards

What is an advantage of a constant-speed propeller?

permits the pilot to select the blade angle for the most efficient performance

66
New cards

One purpose of the dual ignition system on an aircraft engine is to provide for

improved engine performance

67
New cards

If the ignition switch ground wire becomes disconnected, the magneto

may continue to fire

68
New cards

With regard to carburetor ice, float-type carburetor systems in comparison to fuel injection systems are generally considered to be

more susceptible to icing

69
New cards

What condition is most favorable to the development of carburetor icing?

Temperature between 20°F and 70°F and high humidity

70
New cards

The possibility of carburetor icing exists even when the ambient air temperature is as

high as 70°F and the relative humidity is high

71
New cards

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

decrease of RPM

72
New cards

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 (#2)

loss of RPM

73
New cards

The operating principle of float-type carburetors is based on the

difference in air pressure at the venturi throat and the air inlet

74
New cards

The presence of carburetor ice in an aircraft equipped with a fixed-pitch propeller can be verified by applying carburetor heat and noting

a decrease in RPM and then a gradual increase in RPM

75
New cards

Generally speaking, the use of carburetor heat tends to

decrease engine performance

76
New cards

Applying carburetor heat will

enrich the fuel/air mixture

77
New cards

What change occurs in the fuel/air mixture when carburetor heat is applied?

The fuel/air mixture becomes richer

78
New cards

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?

check the results obtained with a leaner setting of the mixture

79
New cards

The basic purpose of adjusting the fuel/air mixture at altitude is to

decrease the fuel flow in order to compensate for decrease air density

80
New cards

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?

The fuel/air mixture may become excessively lean

81
New cards

Fuel/air ratio is the ratio between the

weight of fuel and weight of air entering the cylinder

82
New cards

Detonation occurs in a reciprocating aircraft engine when

the unburned charge in the cylinders explodes instead of burning evenly

83
New cards

Detonation may occur at high-power settings when

the fuel mixture ignites instantaneously instead of burning progressively and evenly

84
New cards

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

lower the nose slightly to increase airspeed

85
New cards

If the grade of fuel used in an aircraft engine is lower than specified for the engine, it will most likely cause

detonation

86
New cards

The uncontrolled firing of the fuel/air charge in advance of normal spark ignition is known as

pre-ignition

87
New cards

What type fuel can be substituted

the next higher octane aviation gas

88
New cards

Filling the fuel tanks after the last flight of the day is considered a good operating procedure because this will

prevent moisture condensation by eliminating airspace in the tanks

89
New cards

To properly purge water from the fuel system of an aircraft equipped with fuel tank sumps and a fuel strainer quick drain, it is necessary to drain fuel from the

fuel strainer drain and the fuel tank sumps

90
New cards

On aircraft equipped with fuel pumps, when is the auxiliary electric driven pump used?

In the event engine-driven fuel pump fails

91
New cards

92
New cards

What should be the first action after starting an aircraft engine?

Adjust for proper RPM and check desired indications on the engine gauges

93
New cards

Should it become necessary to handprop an airplane engine, it is extremely important that a competent pilot

be at the controls on the flight deck

94
New cards

During preflight in cold weather, crankcase breather lines should receive special attention because they are susceptible to being clogged by

ice from crankcase vapors that have condensed and subsequently frozen

95
New cards

An electrical system failure (battery and alternator) occurs during flight. In this situation, you would

experience avionics equipment failure

96
New cards

shows the rate of charge on the battery

97
New cards

higher than the battery voltage

98
