Weather - FAA Drone Quiz

Question 1

What causes variations in altimeter settings between weather reporting points?

Accepted Answer

Unequal heating of the Earth's surface.

Answer

Variation of terrain elevation.

Answer

Coriolis force.

Question 2

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

Accepted Answer

High temperature, high relative humidity, low density altitude

Answer

Low temperature, low relative humidity, low density altitude

Answer

High temperature, low relative humidity, high density altitude

Question 3

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.

Accepted Answer

400 feet AGL

Answer

500 feet AGL

Answer

200 feet AGL

Question 5

A pilot experiencing the effects of hyperventilation should be able to restore the proper carbon dioxide level in the body by

Accepted Answer

increasing the breathing rate in order to increase lung ventilation

Answer

slowing the breathing rate, breathing into a paper bag, or talking aloud

Answer

breathing spontaneously and deeply or gaining mental control of the situation

Question 6

A temperature inversion would most likely result in which weather condition?

Accepted Answer

An increase in temperature as altitude is increased.

Answer

Clouds with extensive vertical development above an inversion aloft.

Answer

Good visibility in the lower levels of the atmosphere and poor visibility above an inversion aloft.

Question 7

One weather phenomenon which will always occur when flying across a front is a change in the

Accepted Answer

wind direction.

Answer

stability of the air mass.

Answer

type of precipitation.

Question 8

Which factor would tend to increase the density altitude at a given airport?

Accepted Answer

An increase in ambient temperature.

Answer

An increase in barometric pressure.

Answer

A decrease in relative humidity.

Question 9

The conditions necessary for the formation of cumulonimbus clouds are a lifting action and

Accepted Answer

unstable, moist air.

Answer

either stable or unstable air.

Answer

unstable air containing an excess of condensation nuclei.

Question 10

Which weather phenomenon is always associated with a thunderstorm?

Accepted Answer

Lightning

Answer
