Gleim: Airplane Instruments, Engines, and Systems

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

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.

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

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

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

The next higher octane aviation gas.

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

The fuel/air mixture becomes richer.

A turn coordinator provides an indication of the

movement of the aircraft about the yaw and roll axes.

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

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

In the Northern Hemisphere, if an aircraft is accelerated or decelerated, the magnetic compass will normally indicate

correctly when on a north or south heading.

In the Northern Hemisphere, a magnetic compass will normally indicate a turn toward the north if

an aircraft is accelerated while on an east or west heading.

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.

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

Reduce rate of speed and increase airspeed

For internal cooling, air cooled engines are especially dependent on

the circulation of lubricating oil.

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 the circumstances, what would be the most logical initial action?

Check the results obtained with a leaner setting of the mixture

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

high as 70°F and the relative humidity is high.

What should be the indication on the magneto compass as you roll into a standard right turn to the right from a south heading and the northern hemisphere

The compass will indicate a turn to the right, but at a faster rate than is actually occurring

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

Higher than the battery voltage

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

Fuel/air ratio is the ratio between the

weight of fuel and weight of air entering the cylinder.

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.

During flight, when are the indications of a magnetic compass accurate?

Only in straight-and-level unaccelerated flight.

What is pressure altitude?

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

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

Offer new capabilities and simplify the basic flying task

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

The next higher octane aviation gas

What is an advantage of a constant speed propeller?

Permits the pilot to select the blade angle for the most effective performance

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

Situational awareness is increased

Excessively high engine temperatures will

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

What is an advantage of a constant-speed propeller?

Permits the pilot to select the blade angle for the most efficient performance.

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

A. The master creates current that is supplied to the electrical system.

B. Lights and radios use the electrical system for power.

C. The airspeed indicator is driven by the electrical system.

Lights and radios use the electrical systems for power

Under what condition is indicated altitude the same as true altitude?

When at sea level under standard conditions.

Which instrument(s) will become inoperative if the static vents become clogged?

Airspeed indicator, altimeter, and vertical speed indicator.

Under which condition will pressure altitude be equal to true altitude?

When standard atmospheric conditions exist

Applying carburetor heat will

enrich the fuel/air mixture

In the northern hemisphere, the magnetic compass will normally indicate a turn toward the south when

The aircraft is decelerated while on a west heading

Which instrument will become inoperative if the pitot tube becomes clogged?

Airspeed indicator

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.

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.

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

Enrich the fuel 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.

How do variations in temperature affect the altimeter?

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

Under what condition is indicated altitude the same as true altitude?

When at sea level under standard conditions.

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.

An abnormally high engine oil temperature indication may be caused by

the oil level being too low.

What should be the indication on the magnetic compass as you roll into a standard rate turn to the right from a south heading in the Northern Hemisphere?

The compass will indicate a turn to the right, but at a faster rate than is actually occurring

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

Situational awareness is increased.

Deviation error of the magnetic compass is caused by

certain metals and electrical systems within the aircraft.

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.

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
