Perfectly

Under what condition is the pressure altitude and density altitude the same value

at standard temperature

Under which condition will pressure altitude be equal to true altitude

when standard atmospheric conditions exist

If it is necessary to set the altimeter from 29.15 to 29.85, what change occurs

700-foot increase in indicated altitude

If a pilot changes the altimeter setting from 30.11 to 29.96, what is the approximate change in indication

altimeter will indicate 150 feet lower

If a flight is made from an area of low pressure into an area of high pressure without the altimeter setting being adjusted, the altimeter will indicate

lower than the actual altitude above sea level

If a flight is made from an area of high pressure into an area of lower pressure without the altimeter setting being adjusted, the altimeter will indicate

higher than the actual altitude above sea level

Which condition would cause the altimeter to indicate a lower altitude than true altitude

air temperature warmer than standard

Under which condition will true altitude be lower than indicated altitude

in colder than standard air temperature

How do variations in temperature affect the altimeter

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

A turn coordinator provides an indication of the

movement of the aircraft about the yaw and roll axes

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

periodically realigned with the magnetic compass as the gyro precesses

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

miniature airplane to the horizon bar

How should a pilot determine the direction of bank from an attitude indicator

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

What is the benefit of flying with a glass cockpit

situational awareness is increased

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

An aircraft which is equipped with an Electronic Flight Display can

offer new capabilities and simplify the basic flying task

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

airspeed indicator

An abnormally high engine oil temperature indication may be caused by

the oil level being too low

Excessively high engine temperatures will

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

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

For internal cooling, air cooled engines are specially dependent on

the circulation of lubricating oil

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

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

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

enrich the fuel mixture

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 gauges and the propeller control regulates engine RPM

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

avoid high manifold pressure settings with low RPM

What is an advantage of a constant-speed propeller

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

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

improved engine performance

If the ignition switch ground wire becomes disconnected, the magneto

may continue to fire

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

broken magneto ground wire

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

more susceptible to icing

Which condition is most favorable to the development of carburetor icing

temperature between 20F and 70F and high humidity

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

as high as 70F and the relative humidity is high

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

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

loss of RPM

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

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

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

Generally speaking, the use of carburetor heat tends to

decrease engine performance

Applying carburetor heat will

enrich the fuel/air mixture

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

the fuel/air mixture becomes richer

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

the next higher octane aviation gas

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

prevent moisture condensation by eliminating airspace in the tanks

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

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

in the event engine-driven fuel pump fails

Which would most likely cause the cylinder head temperature and engine oil temperature gauges to exceed their normal operating ranges

using fuel that has a lower-than-specified fuel rating

What should be the first action after starting an aircraft engine

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

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

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 condense and subsequently frozen

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

experience avionics equipment failure

A positive indication on an ammeter

shows the rate of charge on the battery

To keep a battery charged, the alternator voltages 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
