Weather Phenomena and UAS Operations

Mr. Mig's video tutorial covers the weather section of the FAA Part 107 exam, focusing on visibility, cloud types, thunderstorms, and weather conditions affecting flying. It explains the requirements for flying near clouds, the types of clouds and their characteristics, and the impact of weather phenomena like icing and fog on flight operations. The video also provides tips for determining local visibility and understanding dew point and fog formation.

What is the minimum horizontal distance you must maintain from a cloud when flying a UAS?

• 3000 feet

• 500 feet

• 2000 feet

• 1000 feet

How can a remote pilot determine local visibility?

• By checking the weather forecast

• By using a visibility meter

• By estimating based on previous flights

• By verifying a known point at least three statute miles away

Which type of cloud is characterized by steady precipitation and stable air?

• Cumulonimbus

• Cumulus

• Stratus

• Altostratus

What type of cloud is a cumulonimbus cloud?

• A low cloud

• A middle cloud

• A high cloud

• A thunderstorm cloud

What is the minimum visibility required for UAS operations?

• 1 mile

• 2 miles

• 4 miles

• 3 miles

What conditions are necessary for the formation of a thunderstorm?

• Low humidity, lifting force, and stable conditions

• High humidity, lifting force, and stable conditions

• High humidity, lifting force, and unstable conditions

• Low humidity, lifting force, and unstable conditions

What is structural icing and when does it occur?

• When snow accumulates on a cold surface

• When water vapor condenses on a warm surface

• When supercooled water droplets contact a surface below freezing

• When rain falls on a hot surface

What is the dew point?

• The temperature at which air becomes dry

• The temperature at which ice melts

• The temperature at which water boils

• The temperature at which air must be cooled to become saturated with water vapor

Which type of fog is most likely to form in warm, moist air over low flat land areas on clear, calm nights?

• Steam fog

• Upslope fog

• Radiation fog

• Advection fog

What type of fog forms when warm, moist air moves over cooler ground or water?

• Steam fog

• Advection fog

• Upslope fog

• Radiation fog
