SPC Aeromedical Factors 2

Question 1

A pilot experiences tunnel vision and a narrowing field of view at high altitude. This is most likely caused by:

Accepted Answer

Hypoxia reducing peripheral vision

Answer

Hypoxia impairs the retina's oxygen-sensitive cells, causing tunnel vision as one of its early symptoms.

Question 2

Which condition is MOST likely to cause a pilot to feel falsely confident about their own performance?

Accepted Answer

Hypoxia

Answer

Hypoxia produces a feeling of euphoria and overconfidence, which is particularly dangerous because the pilot may not recognize impairment.

Question 3

During a climb to 12,500 feet MSL, a student pilot begins to feel dizzy and tingling in the fingers. The FIRST action should be:

Accepted Answer

Descend to a lower altitude immediately

Answer

Descending to a lower altitude where oxygen partial pressure is higher is the immediate corrective action for hypoxia.

Question 4

Which of the following BEST describes 'spatial disorientation'?

Accepted Answer

A conflict between what the body senses and what the instruments indicate

Answer

Spatial disorientation occurs when conflicting signals from the vestibular system, muscles, and vision disagree with actual instrument readings.

Question 5

A pilot who has been scuba diving to 30 feet should wait at least how long before flying to cabin altitudes above 8,000 feet?

Accepted Answer

24 hours

Answer

FAA recommends waiting at least 24 hours after any dive that required a controlled ascent (decompression stop dives) before flying above 8,000 feet.
