Weather - FAA Part 107 Drone Exam Prep

Question 1

Thunderstorms require three elements to form: high moisture, an unstable lapse rate (instability), and:

Accepted Answer

A lifting force (such as heating from below or a frontal boundary).

Answer

High barometric pressure.

Answer

A strong temperature inversion.

Question 2

Which is true regarding the effect of alcohol on the human body?

Accepted Answer

Any amount of alcohol can affect a person's judgment and decision-making capacity.

Answer

Consuming an equal amount of water will accelerate the metabolization of alcohol and help a person regain their normal senses in less than 8 hours.

Answer

A minimal amount of alcohol will have no effects on a person's situational awareness and ability to make decisions.

Question 3

What is the primary danger to a drone pilot when flying in an area with a strong temperature inversion?

Accepted Answer

Poor visibility due to trapped smoke, dust, and haze in the lower atmosphere, making VLOS difficult.

Answer

The battery will overheat due to the rapidly rising air.

Answer

The drone will be pushed uncontrollably upward into controlled airspace.

Question 4

Which combination of atmospheric conditions will result in the most optimal propeller efficiency?

Accepted Answer

Low temperature, low relative humidity, low density altitude.

Answer

High temperature, low relative humidity, high density altitude.

Answer

High temperature, high relative humidity, low density altitude.

Question 5

At what altitude does wind shear occur?

Accepted Answer

At any altitude.

Answer

Below 5,000 feet AGL.

Answer

Above 20,000 feet MSL.

Question 6

What type of weather is generally associated with an advancing cold front?

Accepted Answer

Towering cumulus clouds, showery precipitation, and thunderstorms.

Answer

Stratiform clouds, widespread rain, and poor visibility.

Answer

Clear skies and calm winds.

Question 7

What conditions are necessary for the formation of thunderstorms?

Accepted Answer

High humidity, lifting force, and unstable conditions.

Answer

Lifting force, moist air, and extensive cloud cover.

Answer

High humidity, high temperature, and cumulus clouds.

Question 8

Why is frost considered hazardous to drone operations?

Accepted Answer

It disrupts the smooth flow of air over the airfoil, decreasing lift and increasing drag.

Answer

It adds immense weight to the aircraft, dragging it down.

Answer

It shorts out the electronic speed controllers.

Question 9

What visual cue can a remote pilot use to anticipate the presence of a microburst?

Accepted Answer

A rain shaft descending from a thunderstorm, especially if the rain evaporates before hitting the ground (virga), combined with a ring of blowing dust at the surface.

Answer

A perfectly clear, blue sky.

Answer

A layer of flat, low-lying stratus clouds.

Question 10

What combination of atmospheric factors produces the highest density altitude?

Accepted Answer

High elevation, high temperature, and high humidity.

Answer

Low elevation, low temperature, and low humidity.

Answer

High elevation, low temperature, and high humidity.
