Q

Generally speaking, the use of carburetor heat tends to

A

Decrease engine performance

22
Q

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

A

More susceptible to icing

23
Q

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

A

Temperature between 20 and 70F and high humidity

24
Q

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

A

In the event engine-driven fuel pump fails

25
Q

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

A

Detonation

26
Q

Detonation may occur at high-power settings when

A

The fuel mixture ignites instantaneously instead of burning progressively and evenly

27
Q

Detonation occurs in a reciprocating aircraft engine when

A

The unburned charge in the cylinders explodes instead of burning properly

28
Q

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

A

Pre-ignition

29
Q

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

A

The next higher octane aviation gas

30
Q

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

A

Prevent moisture condensation by eliminating airspace in the tank

31
Q

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

A

Fuel strainer drain and the fuel tank sumps

32
Q

During preflight in cold weather, crankcase breather lines should receive special attention because they are susceptible to being clogged by…

A

Ice from crankcase vapors that have condensed and subsequently frozen

33
Q

If a pilot suspects that the engine(with a fixed-pitch ch propeller) is detonating during climbout after takeoff, the initial corrective action to take would be to….

A

Lower the nose slightly to increase airspeed

34
Q

Excessively high engine temperatures will

A

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

35
Q

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

A

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

36
Q

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

A

Too much power and with the mixture set too lean

37
Q

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

A

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

38
Q

For internal cooling, reciprocating aircraft engines are especially dependent on

A

The circulation of lubricating oil.

39
Q

Which is true regarding preheating an aircraft during cold weather operations?

A

The cabin area as well as the engine should be preheated

40
Q

An abnormally high engine oil temperature indication may be caused by

A

The oil being too low

41
Q

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

A

Reduce rate of climb and increase airspeed

42
Q

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

A

Enrichen the fuel mixture

43
Q

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

A

Immediately establish the proper gliding attitude and airspeed

44
Q

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

A

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

45
Q

What is an advantage of a constant-speed propeller?

A

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

46
Q

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

A

Avoid high manifold pressure settings with low RPM

47
Q

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

A

Low airspeed, high power, high angle of attack

48
Q

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

A

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

49
Q

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

A

When at high angle of attack

50
Q

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

A

The pilot in command

51
Q

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

A

Thorough and systematic means recommended by the manufacturer

52
Q

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