Aircraft Systems Flashcards
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.
What change occurs in the air-fuel mixture when carburetor heat is applied?
The air-fuel mixture becomes richer.
During a night flight, you observe a steady white light and a flashing red light ahead and at the same altitude.
What is the general direction of movement of the other aircraft?
The other aircraft is flying away
from you.
Applying carburetor heat will
enrich the air-fuel mixture.
While cruising at 9,500 feet MSL, the air-fuel mixture is properly adjusted.
What will occur if a descent to 4,500 feet MSL is made without readjusting the mixture?
The air-fuel mixture may become excessively lean.
What type fuel can be substituted for an aircraft if the recommended octane is not available?
The next higher octane aviation gas.
An abnormally high engine oil temperature indication may be caused by
the oil level being too low.
What is one procedure to aid in cooling an engine that is overheating?
Enrichen the fuel mixture.
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?
Check the results obtained with a leaner setting of the mixture.
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 possibility of carburetor icing exists even when the ambient air
temperature is as
high as 70°F and the relative humidity is high.
During a night flight, you observe a steady red light and a flashing red light ahead and at the same altitude. What is the general direction of movement of the other aircraft?
The other aircraft is crossing to
the left.
It the grade of tuel used in an aircraft engine is lower than specified for the
engine, it will most likely cause
detonation.
Excessively high engine temperatures will
cause loss of power, excessive oil consumption, and possible permanent internal engine damage.
How should an aircraft preflight inspection be accomplished for the first flight of the day?
Thorough and systematic means recommended by the manufacturer.
Should it become necessary to handprop an airplane engine, it is extremely important that a competent pilot
be at the controls in the flight deck.
During a night flight, you observe steady red and green lights ahead and at the
same altitude. What is the general direction of movement of the other aircraft?
The other aircraft is approaching head on
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
For internal cooling, reciprocating aircraft engines are especially dependent
on
the circulation of lubricating oil.
Generally speaking, the use of carburetor heat tends to
decrease engine performance.
In what flight condition are torque effects more pronounced in a single-engine airplane?
Low airspeed, high power, high angle
of attack.
Pilots are encouraged to turn on their landing lights when operating below 10,000 feet, day or night, and when operating within
10 miles of any airport.
When does P-factor cause the airplane to yaw to the left?
When at high angles of attack.
If the ground wire between the magneto and the ignition switch becomes disconnected, the most noticeable result will be that the engine
cannot be shut down by turning the switch to the OFF position.
