Exam 4
True airspeed is best described as calibrated airspeed corrected for
Altitude and nonstandard temperature
Hypoxia susceptibility due to inhalation of carbon monoxide increases as
Altitude increases
Which of the following statements concerning the combination of alcohol and altitude is true?
Altitude multiplies the effects of alcohol
A propeller's angle of incidence is the greatest
At the hub, which permits the same amount of lift to be created along the blade's length
The reason a 4-cylinder reciprocating engine continues to run after the ignition switch is positioned to OFF may be a
Broken magneto ground wire
The basic purpose of adjusting the fuel/air mixture control at altitude is to
Decrease the fuel flow to compensate for decreased air density
Why should flight speeds above never exceed speed be avoided?
Design limit load factors may be exceeded, if gusts are encountered
Which of the following could increase susceptibility to hypoxia?
Flying after donating blood
At high altitudes, an excessively rich mixture will cause the
Fouling of spark plugs
The angle of attack of a cruise propeller is
Higher than that of a climb propeller and creates more drag
In aircraft equipped with constant-speed propellers and normally-aspirated engines, which procedure should be used to avoid placing undue stress on the engine components? When power is being
Increased, increase the RPM before increasing the manifold pressure
What is an operational difference between the turn coordinator and the turn-and-slip indicator? The turn coordinator
Indicates roll rate, rate of turn, and coordination; the turn-and-slip indicator indicates rate of turn and coordination
Altitude-induced hypoxia is caused by what atmospheric condition?
Insufficient partial pressure of the inhaled oxygen
Which statement is true concerning the effect of the application of carburetor heat?
It enriches the fuel/air mixture
A propeller rotating clockwise as seen from the rear, creates a spiraling slipstream. The spiraling slipstream, along with torque effect, tends to rotate the airplane to the
Left around the vertical axis, and to the right around the longitudinal axis
The illusion associated with landing on a narrower than usual runway may result in the pilot flying a
Lower approach with the risk of striking objects along the approach path or landing short
If a pilot has not consumed a drink in 12 hours, and has a blood alcohol level of .04 percent, can they fly?
No, the pilot has a blood alcohol level of .04
A pilot who needs to overcome the effects of spatial disorientation should
Place a greater emphasis on the flight instruments
The horizontal dashed line from point C to point E represents the ( FIGURE 73)
Positive limit load factor
The uncontrolled firing of the fuel/air charge in advance of normal spark ignition is known as
Preignition
A detuning of engine crankshaft counterweights is a source of overstress that may be caused by
Rapid opening and closing of the throttle
Propeller efficiency is the
Ratio of thrust horsepower to brake horsepower
What is a benefit of flying with a glass flight deck?
Situational awareness is increased
To overcome the symptoms of hyperventilation, a pilot should
Slow the breathing rate
As hyperventilation progresses a pilot can experience
Symptoms of suffocation and drowsiness
Which technique should a pilot use to scan for traffic to the right and left during straight-and-level flight?
Systematically focus on different segments of the sky for short intervals
The best power mixture is that fuel/air ratio at which
The most power can be obtained for any given throttle setting
An abnormally high engine oil temperature indication may be caused by
The oil level being too low
Which statement best describes the operating principle of a constant-speed propeller?
The propeller control regulates the engine RPM and in turn the propeller RPM
Fuel air ratio is the ratio between the
Weight of fuel and weight of air entering the cylinder
