Question 1

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 2

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.

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 4

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 5

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

Accepted Answer

Rain-induced fog

Answer

Upslope fog

Answer

Steam fog

Question 7

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 8

Question 12

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 13

What situation is most conducive to the formation of radiation fog?

Accepted Answer

The movement of cold air over much warmer water.

Answer

Moist, tropical air moving over cold, offshore water.

Answer

Warm, moist air over low, flatland areas on clear, calm nights
