A pilot experiences tunnel vision and a narrowing field of view at high altitude. This is most likely caused by:
Answer: Hypoxia reducing peripheral vision
Hypoxia impairs the retina's oxygen-sensitive cells, causing tunnel vision as one of its early symptoms.
Which condition is MOST likely to cause a pilot to feel falsely confident about their own performance?
Answer: Hypoxia
Hypoxia produces a feeling of euphoria and overconfidence, which is particularly dangerous because the pilot may not recognize impairment.
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:
Answer: Descend to a lower altitude immediately
Descending to a lower altitude where oxygen partial pressure is higher is the immediate corrective action for hypoxia.
Which of the following BEST describes 'spatial disorientation'?
Answer: A conflict between what the body senses and what the instruments indicate
Spatial disorientation occurs when conflicting signals from the vestibular system, muscles, and vision disagree with actual instrument readings.
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?
Answer: 24 hours
FAA recommends waiting at least 24 hours after any dive that required a controlled ascent (decompression stop dives) before flying above 8,000 feet.
The 'leans' is a form of spatial disorientation in which a pilot:
Answer: Believes the aircraft is in a bank when instruments show wings level
The leans occur when the vestibular system incorrectly senses a bank, causing the pilot to feel tilted even though instruments confirm wings-level flight.
Which statement about carbon monoxide (CO) poisoning in an aircraft is correct?
Answer: CO binds to hemoglobin more readily than oxygen, reducing blood oxygen capacity
CO displaces oxygen by binding to hemoglobin roughly 200 times more readily than oxygen, severely reducing the blood's oxygen-carrying capacity.
