UAS Weather
Which of the following considerations is most relevant to a remote PIC when evaluating unmanned
aircraft performance? - correct answer ✔✔Current weather conditions
Every physical process of weather is accompanied by, or is the result of, a - correct answer ✔✔heat
exchange
What causes variations in altimeter settings between weather reporting points? - correct answer
✔✔Unequal heating of the Earth's surface
The development of thermals depends upon - correct answer ✔✔solar heating
(Refer to Figure 20) Over which area should a Remote Pilot expect to find the highest amount of thermal
currents under normal conditions? - correct answer ✔✔2
Clouds, fog, or dew will always form when - correct answer ✔✔water vapor condenses
While operating around buildings, the remote PIC should be aware of the creation of wind gusts that -
correct answer ✔✔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 operation? - correct answer ✔✔Turbulent conditions will likely be a significant factor during
the operation.
Wind shear can exist - correct answer ✔✔at all altitudes.
One of the most easily recognized discontinuities across a front is - correct answer ✔✔a change in
temperature.
, One weather phenomenon which will always occur when flying across a front is a change in the - correct
answer ✔✔wind direction.
Which type of weather phenomenon that may concern a remote pilot is common among cold fronts? -
correct answer ✔✔Thunderstorms and heavy rain.
What weather provides the best flying conditions? - correct answer ✔✔Cool, dry air.
The zone between different temperature, humidity and wind is called - correct answer ✔✔A front.
A stable air mass is most likely to have which characteristic? - correct answer ✔✔Poor surface visibility.
What are characteristics of a moist, unstable air mass? - correct answer ✔✔Turbulence and showery
precipitation.
What are characteristics of stable air? - correct answer ✔✔Poor visibility and steady precipitation.
What measurement can be used to determine the stability of the atmosphere?
Atmospheric pressure
Actual lapse rate
Surface temperature - correct answer ✔✔Actual lapse rate.
What would decrease the stability of an air mass?
Warming from below
Cooling from below
Decrease in water vapor - correct answer ✔✔Warming from below.
