Aircraft Systems🧩

Front 1

The left turning tendency of an airplane caused by P-factor is the result of the

Back 1

propeller blade descending on the right, producing more thrust than the ascending blade on the left

Front 2

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

Back 2

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

Front 3

If the ground wire between the magneto and the ignition switch becomes disconnected, the most noticeable result will be that the engine

Back 3

cannot be shut down by turning the switch to the OFF position

Front 4

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

Back 4

Pre ignition

Front 5

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

Back 5

Temperature between 20 and 70°F and high humidity.

Front 6

When does P-factor cause the airplane to yaw to the left?

Back 6

When at high angles of attack.

Front 7

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

Back 7

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

Front 8

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?

Back 8

The fuel/air mixture may become excessively lean.

Front 9

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

Back 9

too much power and with the mixture set too lean.

Front 10

What is one purpose for using reciprocating engines?

Back 10

They are relatively simple and inexpensive to operate.

Front 11

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

Back 11

The next higher octane aviation gas.

Front 12

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?

Back 12

Check the results obtained with a leaner setting of the mixture.

Front 13

An abnormally high engine oil temperature indication may be caused by

Back 13

The oil level being too low

Front 14

In what flight condition is torque effect the greatest in a single-engine airplane?

Back 14

Low airspeed, high power, high angle of attack.

Front 15

Generally speaking, the use of carburetor heat tends to

Back 15

Decrease engine preformance

Front 16

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

Back 16

Improved engine performance

Front 17

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

Back 17

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

Front 18

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

Back 18

experience avionics equipment failure.

Front 19

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

Back 19

a decrease in RPM and then a gradual increase in RPM.

Front 20

Excessively high engine temperatures will

Back 20

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

Front 21

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

Back 21

prevent moisture condensation by eliminating airspace in the tanks.

Front 22

Who is primarily responsible for maintaining an aircraft in airworthy condition?

Back 22

Owner and operator

Front 23

For internal cooling, reciprocating aircraft engines are especially dependent on

Back 23

the circulation of lubricating oil.

Front 24

The most important rule to remember in the event of a power failure after becoming airborne is to

Back 24

immediately establish the proper gliding attitude and airspeed.

Front 25

Carburetor icing can occur with an OAT as high as

Back 25

20° C and high relative humidity.

Front 26

Detonation may occur at high-power settings when

Back 26

the fuel mixture ignites instantaneously instead of burning progressively and evenly.

Front 27

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

Back 27

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

Front 28

During the preflight inspection who is responsible for determining the aircraft is safe for flight?

Back 28

Pilot in command

Front 29

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

Back 29

Enrich fuel mixture

Front 30

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

Back 30

Reduce rate of climb and increase airspeed.

Front 31

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

Back 31

Detonation

Front 32

How should an aircraft preflight inspection be accomplished for the first flight of the day?

Back 32

Thorough and systematic means recommended by the manufacturer.

Front 33

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

Back 33

Lower the nose slightly to gain airspeed

Front 34

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

Back 34

The fuel/air mixture becomes richer.

Front 35

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

Back 35

Loss of RPM

Front 36

What is an advantage of a constant-speed propeller?

Back 36

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

Front 37

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

Back 37

fuel strainer drain and the fuel tank sumps.

Front 38

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

Back 38

In the event engine-driven fuel pump fails.

Front 39

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

Back 39

avoid high manifold pressure settings with low RPM.

Front 40

Applying carburetor heat will

Back 40

Enrich fuel/air mixture

Front 41

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

Back 41

Using fuel that has a lower-than-specified fuel rating.

Front 42

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

Back 42

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

Front 43

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

Back 43

be at the controls in the cockpit.

Front 44

Detonation occurs in a reciprocating aircraft engine when

Back 44

the unburned charge in the cylinders explodes instead of burning normally.

Front 45

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

Back 45

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

Front 46

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

Back 46

more susceptible to icing.
