Weather Quiz

Conditions favorable for radiation fog are clear sky, little or no wind, and small temperature/dew point spread (high relative humidity). Radiation fog is restricted to land because water surfaces cool little from nighttime radiation.Answer (B) is incorrect because radiation fog will not form over water since water surfaces cool little from nighttime radiation. Answer (C) is incorrect because radiation fog will not form over water since water surfaces cool little from nighttime radiation.

Local conditions, geological features, and other anomalies can change the wind direction and speed close to the Earth's surface, making it difficult to control and maneuver the sUAS.

Ice pellets always indicate freezing rain at higher altitude.

Wind direction always changes across a front.Answer (B) is incorrect because precipitation does not always exist with a front. Answer (C) is incorrect because the stability on both sides of the front may be the same.

Part 107 require the minimum distance of the sUAS from clouds must be no less than 500 feet below the cloud. 800 - 500 = 300 feet AGL.
