Which of the following considerations is most relevant to a remote PIC when evaluating unmanned
aircraft performance?
A - Current weather conditions.
B - The number of available ground crew.
C - The type of sUAS operation. - correct answer ✔✔A - Current weather conditions.
Every physical process of weather is accompanied by, or is the result of, a
A - movement of air.
B - pressure differential.
C - heat exchange. - correct answer ✔✔C - heat exchange.
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. - correct answer ✔✔A - Unequal heating of the Earth's surface.
The development of thermals depends upon
A - a counterclockwise circulation of air.
B - temperature inversions.
C - solar heating. - correct answer ✔✔C - solar heating.
1139. (Refer to Figure 20.) Over which area should a Remote Pilot expect to find the highest amount of
thermal currents under normal conditions?
A - 2.
B - 7.
C - 5. - correct answer ✔✔A - 2.
, Clouds, fog, or dew will always form when
A - water vapor condenses.
B - water vapor is present.
C - relative humidity reaches 100 percent. - correct answer ✔✔A - water vapor condenses.
While operating around buildings, the remote PIC should be aware of the creation of wind gusts that
A - change rapidly in direction and speed causing turbulence.
B - enhance stability and imagery.
C - increase performance of the aircraft - correct answer ✔✔A - change rapidly in direction and speed
causing turbulence.
A strong steady wind exists out of the north. You need to photograph an area to the south of your
location. You are located in an open field with no obstructions. Which of the following is not a concern
during this operaton?
A - Strong wind conditions may consume more battery power at a faster rate than in calm conditions.
B - Turbulent conditions will likely be a significant factor during the operation.
C - Strong wind may exceed the performance of the sUAS making it impossible to recover. - correct
answer ✔✔B - Turbulent conditions will likely be a significant factor during the operation.
1278. Wind shear can exist
A - at all altitudes.
B - at low altitudes.
C - at high altitudes. - correct answer ✔✔A - at all altitudes.
One of the most easily recognized discontinuities across a front is
A - a change in temperature.
B - an increase in cloud coverage.
C - an increase in relative humidity. - correct answer ✔✔A - a change in temperature.
