Air temperature lower than standard

Atmospheric pressure lower than standard

Under what condition will true altitude be lower than indicated altitude?

In colder than standard air temperature

In warmer than standard air temperature

When density altitude is higher than indicated altitude

How do variations in temperature affect the altimeter?

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

Hhighertemperatures expand the pressure levels and the indicated altitude is higher than true altitude

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

Excessively high engine temperatures will

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

Cause damage to heat-conducting hoses and warping of the cylinder cooling fins

Not appreciably affect an aircraft engine

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

Increase fuel consumption and may increase power due to the increased heat

Result in damage to heat-conducting hoses and warping of cylinder cooling fans

For internal cooling, air cooled engines are especially dependent on

The circulation of lubricating oil

A properly functioning thermosat

Air flowing over the exhaust manifold

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

Reduce climb speed and increase RPM

Increase climb speed and increase RPM

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 gage and the propeller control regulates engine RPM

The throttle controls power output as registered on the manifold pressure gage 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

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

Avoid high manifold pressure settings with low RPM

Avoid high RPM settings with high manifold pressure

Always use a rich mixture with high RPM settings

What is an advantage of a constant-speed propeller?

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

Permits the pilot to select and maintain a desired cruising speed

Provides a smoother operation with stable rpm and climates vibrations

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

Balanced cylinder head pressure

If the ignition switch ground wire becomes disconnected, the magneto

Will not operate because the battery is disconnected from the circuit

The reason a 4-cylinder reciprocating engine continues to run after the ignition switch is positioned to OFF may be a

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

An abnormally high engine oil temperature indication may be caused by

Operating with a too viscosity oil

Operating with a excessively rich mixture

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

Higher-than-normal oil pressure

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

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

Decrease the amount of fuel in the mixture in order to compensate for increased air density

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

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

There will be more fuel in the cylinders than is needed for normal combustion

he excessively rich mixture will create higher cylinder head temperatures and may cause detonation

Fuel/air is the ratio between the

Weight of fuel and weight of air entering the cylinder

Volume of fuel and volume of air entering the cylinder

Weight of fuel and weight of air entering the carburetor

What type fuel can be substituted for an aircraft if the recommended octane is not available?

The next higher octane aviation gas

The next lower octane aviation gas

Unleaded automotive gas of the same octane rating

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

Prevent moisture condensation by eliminating airspace in the tanks

Force any existing water to the top of the tank away from the fuel lines to the engine

Prevent expansion of the fuel by eliminating airspace in the tanks

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

Fuel strainer drain and the fuel tank sumps

Lowest point in the fuel system

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

In the event engine-driven fuel pump fails

All the time to aid the engine driven fuel pump

Constantly except in starting the engine

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

experience avionics equipment failure

Probably experience failure of the engine ignition system, fuel gauges, aircraft lighting system, and avionics equipment

Probably experience engine failure due to the loss of the engine-driven fuel pump and also experience failure of the ratio equipment, lights, and all instruments that require alternating current

A positive indication on an ammeter

Shows the rate of charge on the battery

Indicates the aircraft's battery will soon lose its charge

Means more current is being drawn from the battery than is being replaced

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

higher than the battery voltage

Which of the following is a true statement concerning electrical systems?

lights and radios use the electrical system for power

The master switch creates current that is supplied to the electrical system

The airspeed indicator is driven by the electrical system

What is a benefit of flying with a glass flight deck?

Situational awareness is increased

There is no longer a need to carry paper charts in flight

Terrain avoidance is guaranteed

What steps must be taken when flying in glass flight decks to ensure safe flight?

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

Use the moving map for primary means of navigation, use the MFD to check engine systems and weather, back up with supplementary forms of information

Regulary scan each item on the PFD, confirm on the MFD

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

Ooffer new capabilities and simplify the basic flying task

Compensate for an airman's lack of skill or knowledge

improve flight awareness by allowing the pilot to simply watch for alerts
