2

Question 4

4. Clouds, fog, or dew will always form when

• water vapor condenses
• relative humidity reaches 100 percent
• water vapor is present

Answer 4

water vapor condenses

Question 5

5. One weather phenomenon which will always occur when flying across a front is a change in the

• Wind direction
• Type of precipitation
• Stability or the air mass

Answer 5

Wind direction

Question 6

6. 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 operation?

• Strong wind may exceed the performance of the sUAS making it impossible to
• Turbulent conditions will likely be a significant factor during the operation
• Strong wind conditions may consume more battery power at a faster rate than in calm conditions

Answer 6

Turbulent conditions will likely be a significant factor during the operation

Question 7

7. While operating around buildings, the remote PIC should be aware of the creation of wind gusts that

• Enhance stability and imagery
• Change rapidly in direction and speed causing turbulence
• Increase performance of the aircraft

Answer 7

Change rapidly in direction and speed causing turbulence

Question 8

8. One of the most easily recognized discontinuities across a front is

• An increase in cloud coverage
• An increase in relative humidity
• A change in temperature

Answer 8

A change in temperature

Question 9

9. The zone between different temperature, humidity, and wind is called

• An air mass
• Wind shear
• A front

Answer 9

A front

Question 10

10. Wind shear can exist

• at all altitudes
• at low altitudes
• at high altitudes

Answer 10

at all altitudes

Question 11

11. Which type of weather phenomenon that may concern a remote pilot is common among cold fronts?

• Long periods of steady precipitation
• Thunder storms and heavy rain
• Long term periods of reduced visibility

Answer 11

Thunder storms and heavy rain

Question 12

12. Which of the following considerations is most relevant to a remote PIC when evaluating unmanned aircraft performance?

• Current weather conditions
• The type of SUAS operation
• The number of available ground crew

Answer 12

Current weather conditions

Question 13

13. What causes variations in altimeter settings between weather reporting points?

• Coriolis force
• Unequal heating of the Earth’s surface
• Variation of terrain elevation

Answer 13

Unequal heating of the Earth’s surface

Question 14

14. The development of thermals depends upon

• A counterclockwise circulation of air
• Temperature inversions
• Solar heating

Answer 14

Solar heating
