Answer 1

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

Question 2

The most effective method of scanning for other aircraft for collision avoidance during daylight hours is to use

Answer 2

a series of short, regularly spaced eye movements to search each 10-degree sector.

Question 3

When a stressful situation is encountered in flight, an abnormal increase in the volume of air breathed in and out can cause a condition known as

Answer 3

hyperventilation.

Question 4

Most midair collision accidents occur during

Answer 4

clear days.

Question 5

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

Answer 5

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

Question 6

Why is fatigue hazardous to flight safety?

Answer 6

Fatigue may not be apparent to a pilot until serious errors are made (an impaired pilot is a dangerous pilot).

Question 7

Eye movements during daytime collision avoidance scanning should

Answer 7

not exceed 10 degrees and view each sector at least 1 second.

Question 8

You are a remote pilot for a co-op energy service provider. You are to use your UA to inspect power lines in a remote area 10 hours away from your home office. After the drive, fatigue impacts your abilities to complete your assignment on time. Fatigue can be recognized

Answer 8

as being in an impaired state.

Question 9

A pilot should be able to overcome the symptoms or avoid future occurrences of hyperventilation by

Question 11

Which is true regarding the presence of alcohol within the human body?

Answer 11

Judgment and decision-making abilities can be adversely affected by even small amounts of alcohol.

Question 12

Which technique should a remote pilot use to scan for traffic? A remote pilot should

Answer 12

systematically focus on different segments of the sky for short intervals.

Question 13
