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
If the grade of fuel used in an aircraft engine is lower than specified for the engine, it will most likely to cause
Detonation
26
Detonation may occur at high-power settings when
The fuel mixture ignites instantaneously instead of burning progressively and evenly
27
Detonation occurs in a reciprocating aircraft engine when
The unburned charge in the cylinders explodes instead of burning properly
28
The uncontrolled firing of the fuel/air charge in advance of normal spark ignition is known as
Pre-ignition
29
What type fuel can be substituted for an aircraft if the recommended octane is not available?
The next higher octane aviation gas
30
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 tank
31
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
32
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
33
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....
Lower the nose slightly to increase airspeed
34
Excessively high engine temperatures will
Cause loss of power, excessive oil consumption, and possible permanent internal engine damage.
35
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.
36
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
37
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 furl rating
38
For internal cooling, reciprocating aircraft engines are especially dependent on
The circulation of lubricating oil.
39
Which is true regarding preheating an aircraft during cold weather operations?
The cabin area as well as the engine should be preheated
40
An abnormally high engine oil temperature indication may be caused by
The oil being too low
41
What action can a pilot take to aid in cooling an engine that is overheat d during a climb?
Reduce rate of climb and increase airspeed
42
What is one procedure to aid in cooling an engine that is overheating?
Enrichen the fuel mixture
43
The most important rule to remember in the event of a power failure after becoming airborne is to
Immediately establish the proper gliding attitude and airspeed
44
How is engine operation controlled on an engine equipped with a constant-speed propeller?
The throttle controls power output as register on the manifold pressure gauge and the propeller control regulates engine RPM
45
What is an advantage of a constant-speed propeller?
Permits the pilot to select the blade angle for the most efficient performance
46
A precaution for the operation of an engine equipped with a constant-speed propeller is to
Avoid high manifold pressure settings with low RPM
47
In What flight condition is torque effect the greatest in a single-engine airplane?
Low airspeed, high power, high angle of attack
48
The left tendency of an airplane caused by P-factor is the result of the
Propeller blade descending on the right, producing more thrust than the ascending blade on the left
49
When does P-factor cause the airplane to yaw to the left?
When at high angle of attack
50
During the preflight inspection who is responsible for determining the aircraft is safe for flight?
The pilot in command
51
How should an aircraft preflight inspection be accomplished for the first flight of the day?
Thorough and systematic means recommended by the manufacturer
52
Who is primarily responsible for maintaining an aircraft in airworthy condition?
Owner or operator
