Weather - FAA Part 107 Drone Quiz

Question 1

What effect does haze have on the ability to see traffic or terrain features during flight?

Accepted Answer

All traffic or terrain features appear to be farther away than their actual distance.

Answer

Haze causes the eyes to focus at infinity.

Answer

The eyes tend to overwork in haze and do not detect relative movement easily.

Question 2

Katabatic winds are characterized by:

Accepted Answer

Cold, dense air flowing downhill into a valley, typically at night.

Answer

Warm air rising up a mountain slope during the day.

Answer

High-altitude jet streams dipping into the lower atmosphere.

Question 3

When water vapor condenses, what typically forms?

Accepted Answer

Clouds and fog.

Answer

Strong winds.

Answer

A temperature inversion.

Question 4

What are typical characteristics of unstable air?

Accepted Answer

Good visibility and showery precipitation.

Answer

Continuous, steady precipitation.

Answer

Fog and haze.

Question 5

What is a characteristic of stable air?

Accepted Answer

Stratiform clouds.

Answer

Unlimited visibility.

Answer

Cumulus clouds.

Question 6

How does frost form on an aircraft?

Accepted Answer

When the temperature of the collecting surface is at or below the dew point of the adjacent air, and the dew point is below freezing.

Answer

When water drops freeze upon striking the aircraft's surface.

Answer

When flying through supercooled water droplets.

Question 7

What does a SIGMET (Significant Meteorological Information) advise pilots about?

Accepted Answer

Non-convective weather that is potentially hazardous to all aircraft, such as severe icing, severe turbulence, or dust storms.

Answer

Weather conditions that are only hazardous to small, single-engine aircraft.

Answer

Routine forecasted weather at an aerodrome.

Question 8

Why is 'clear ice' generally considered the most dangerous type of structural icing?

Accepted Answer

Because it is heavy, hard to see, alters the shape of the airfoil, and is difficult to remove.

Answer

Because it only forms at extremely high altitudes out of drone range.

Answer

Because it creates an electromagnetic field that disrupts the drone's compass.

Question 9

Under what condition will the air become fully saturated?

Accepted Answer

When the temperature drops to equal the dew point.

Answer

When the barometric pressure drops below 29.92 Hg.

Answer

When the temperature rises significantly above the dew point.

Question 10

While operating a drone in a desert environment during the afternoon, a remote pilot notices small, swirling columns of dust. These are known as:

Accepted Answer

Dust devils, which indicate unstable air and localized turbulence.

Answer

Microbursts.

Answer

Squall lines.
