QUESTIONS & ANSWERS(RATED A+)
What are characteristics of unstable air?
A. Turbulence and good surface visibility.
B. Turbulence and poor surface visibility.
C. Nimbostratus clouds and good surface visibility.
Unstable air has vertical air currents that produce turbulence and good surface
visibilities. Answer B is incorrect because unstable air will have good visibility due to
the vertical air currents. Answer C is incorrect because if clouds form they would be
cumulus clouds, not stratus clouds. - ANSWERA. Turbulence and good surface
visibility
What effect does haze have on the ability to see traffic or terrain features during
flight?
A. Haze causes the eyes to focus at infinity.
B. The eyes tend to overwork in haze and do not detect relative movement easily.
C. All traffic or terrain features appear to be farther away than their actual distance. -
ANSWERC. All traffic or terrain features appear to be farther away than their actual
distance
(Refer to Figure 48.) That portion of the runway identified by the letter A may be
used for
A. landing.
B. taxiing and takeoff.
C. taxiing and landing. - ANSWERB. taxiing and takeoff
While operating around buildings, the Remote Pilot in Command should be aware of
the creation of wind gusts that:
A. Change rapidly in direction and speed causing turbulence.
B. Increase performance of the aircraft.
C. Enhance stability and imagery. - ANSWERA. Change rapidly in direction and
speed causing turbulence
Exhaust plumes are most dangerous when
A. the surrounding air is calm and cold.
B. they are visible.
C. they come from larger towers. - ANSWERA. the surrounding air is calm and cold
What cloud types would indicate convective turbulence?
A. Cirrus clouds.
, B. Nimbostratus clouds.
C. Towering cumulus clouds. - ANSWERC. Towering cumulus clouds
Rapid or extra deep breathing while using oxygen can cause a condition known as
A. hyperventilation.
B. aerosinusitis.
C. aerotitis. - ANSWERA. hyperventilation
(Refer to Figure 24, area 3.) For information about the parachute operations at Tri-
County Airport, refer to - ANSWERChart Supplements U.S.
What conditions are necessary for the formation of thunderstorms?
A. High humidity, lifting force, and unstable conditions.
B. High humidity, high temperature, and cumulus clouds.
C. Lifting force, moist air, and extensive cloud cover. - ANSWERA. High humidity,
lifting force, and unstable conditions
When an air traffic controller issues radar traffic information in relation to the 12-hour
clock, the reference the controller uses is the aircraft's
A. true course.
B. ground track.
C. magnetic heading. - ANSWERB. ground track
One in-flight condition necessary for structural icing to form is
A. small temperature/dewpoint spread.
B. stratiform clouds.
C. visible moisture. - ANSWERC. visible moisture
The most frequent type of ground or surface-based temperature inversion is that
which is produced by
A. terrestrial radiation on a clear, relatively still night.
B. warm air being lifted rapidly aloft in the vicinity of mountainous terrain.
C. the movement of colder air under warm air, or the movement of warm air over
cold air. - ANSWERA. terrestrial radiation on a clear, relatively still night
What causes variations in altimeter settings between weather reporting points?
A. Unequal heating of the Earth's surface.
B. Variation of terrain elevation.
C. Coriolis force. - ANSWERA. Unequal heating of the Earth's surface
What effect does oxygen have on night vision?
A. As altitude increases, the available oxygen decreases, degrading night vision.
