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

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

Question 3

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 4

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 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

The Coriolis force deflects winds to the ________ in the Northern Hemisphere.

Accepted Answer

Right.

Answer

Left.

Answer

South.

Question 7

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 8

The amount of water vapor which air can hold depends primarily on the:

Accepted Answer

Air temperature.

Answer

Dew point.

Answer

Air pressure.

Question 9

A remote PIC is planning a flight and notices the METAR reads 'FG'. The visibility is reported as 1/4 SM. Under Part 107, can the pilot legally fly?

Accepted Answer

No, Part 107 requires a minimum of 3 statute miles of flight visibility.

Answer

Yes, as long as the drone stays under 100 feet AGL.

Answer

Yes, if the pilot uses FPV goggles.

Question 10

If the altimeter setting at your local airport drops rapidly from 29.92 to 29.50, what kind of weather system is likely approaching?

Accepted Answer

A low-pressure system, which typically brings cloudy, unsettled weather and precipitation.
