Unit 2 FAA prep questions I missed

Which condition would cause the altimeter to indicate lower altitude than true altitude? (61)

Air temperature lower than standard

Atmospheric pressure lower than standard

Air temperature warmer than stander

Air temperature warmer than standard

Under which conditions will true altitude be lower than indicated altitude? (61)

In colder than standard air temperatures

In warmer than standard air temperatures

When density altitude is higher than indicated altitude

In colder than standard air temperatures

How do variations in temperature affect the altimeter? (61)

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

Higher temperatures expand the pressure levels, and the indicated altitude is higher than true altitudes

Lower temperatures lower the pressure levels, and the indicated altitude is lower than the true altitude

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

What is absolute altitude? (60)

Altitude read from the altimeter

The vertical distance above the surface

The height above the standard datum plane

The vertical distance above the surface

Altimeter setting is the value to which the barometric pressure scale of the altimeter is set so the altimeter indicates (60)

calibrated altitude at field elevation

absolute altitude at field elevation

true altitude at field elevation

true altitude at the field elevation

A turn coordinator provides an indication of the (62)

movement of the aircraft about the yaw and roll axes

angle of bank up to but not exceeding 30degrees

attitude of the aircraft with reference to the longitudinal axis

movement of the aircraft about the yaw and roll axes

You are flying an aircraft equipped with an electronic flight display and the air data computer fails. What instrument is affected? (64)

ADS-B in capabilities

Airspeed indicator

Attitude indicator

airspeed indicator

EFD utilizes air data computer (ADC), relieving pitot and static inputs

An abnormally high engine oil temperature indication may be caused by (65)

the oil level being too low

operating with a too high viscosity oil

operating with an excessively rich mixture

the oil levels being too low

not enough oils prevents adequate cooling

rich fuel/air mixture usually decreases engine temperatures

For internal cooling, air cooled engines are especially dependent on (65)

air flowing over the exhaust manifold

the circulation of lubricating oil

the circulation of lubricating oil

air flowing over exhaust manifold has little effect on internal engine cooling

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

the mixture too lean and full power

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

enrich the fuel mixture

increase rpm

reduce airspeed

enrich fuel mixture

increasing rpm only causes more stress on the engine by producing heat

How is engine operation controlled on an engine equipped with a constant-speed propeller? (66)

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

the throttle controls power output as registered on the manifold pressure gauge and the propeller control regulates a constant blade angle

the throttle controls engine RPM as registered on the tachometer and the mixture control regulates the power output

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

The reason a 4-cylindar recuperating engine continues to run after the ignition switch is positioned in the off may be a (67)

fouled spark plug

wire between the magneto and spark plug in contact with the engine casing

broken magneto ground wire

broken magneto ground wire

The operating principle of a float-type carburetor is based on the (69)

automatic meeting of the air at the venturi as the aircraft gains altitude

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

increase in the air velocity in the throat of a venturi causing an increase in air pressure

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

Generally speaking, the use of the carburetor heat tends to (69)

decrease engine performance

increase engine performance

have no effect on engine performance

decrease engine performance

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

The fuel/air mixture becomes richer

the fuel/air mixture becomes leaner

the fuel/air mixture becomes richer

hot air enters replacing warm air therefore the air is thinner

The basic purpose of adjusting the fuel/air mixture at altitude is to (70)

decrease the amount of fuel in the mixture in order to compensate for increase air density

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

increase the amount of fuel in the mixture to compensate for the decrease in pressure density of the air

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

An electrical system failure (battery and alternator) occurs during flight. In this situation, you would (74)

experience avionic equipment failure

experience ignition engine failure

probably experience engine failure due to the loss of engine driven fuel pump

experience avionic equipment failure

ignition engine uses magnetos

engine failure due to loss of engine driven fuel pump. These pumps are mechanical and not driven on electricity

To keep a battery charged, the alternator voltage output should be (74)

less than the battery voltage

equal to the battery voltage

higher than the battery voltage

higher than the battery voltage

alternator should be higher because it’s producing electricity for the battery

also want the battery to have less volts, if the amps is pulling its volts from the battery this can indicate alternator failure
