SPC - Student Pilot Certificate Aeromedical Factors Questions and Answers

Question 1

A pilot flying at 13,000 feet MSL for over 40 minutes without supplemental oxygen begins to experience a false sense of well-being and impaired judgment. Which aeromedical condition is the most likely cause?

Accepted Answer

Hypoxic hypoxia

Answer

Hypoxic hypoxia is a state of oxygen deficiency in the body. It occurs at high altitudes where there is less partial pressure of oxygen. FAA regulations (14 CFR § 91.211) require flight crew to use supplemental oxygen for any portion of a flight over 30 minutes at cabin pressure altitudes between 12,500 and 14,000 feet. Symptoms like euphoria and impaired judgment are classic signs of the onset of hypoxia.

Question 2

During a stressful flight in turbulent conditions, a student pilot begins to breathe rapidly and feels light-headed with tingling in their fingertips. What is the most effective corrective action for these symptoms?

Accepted Answer

Consciously slow the breathing rate, or talk or sing aloud

Answer

These are classic symptoms of hyperventilation, a condition caused by breathing too rapidly and expelling too much carbon dioxide. The proper response is to consciously control the breathing rate. Talking, singing, or breathing into a paper bag (if available) helps restore the proper carbon dioxide balance in the body.

Question 3

A pilot inadvertently flies into a cloud and loses all visual reference to the horizon. They feel a strong sensation of being in a left turn, but the attitude indicator shows the aircraft is in a slight right bank. The pilot should:

Accepted Answer

Trust the flight instruments and disregard the conflicting physical sensations.

Answer

This scenario describes spatial disorientation, a condition where a pilot's perception of their position and motion relative to the Earth is incorrect. In the absence of visual references, the vestibular system (inner ear) can be unreliable and create powerful false sensations. The correct and safe procedure is to rely entirely on the flight instruments.

Question 4

Which of the following is a primary symptom of carbon monoxide poisoning, which can result from a faulty aircraft cabin heating system?

Accepted Answer

Headache, dizziness, and drowsiness

Answer

Carbon monoxide (CO) is a colorless, odorless gas that, when inhaled, prevents the blood from carrying oxygen. Early symptoms often include headache, dizziness, and drowsiness. Bluish discoloration (cyanosis) is a sign of severe hypoxia, while tingling sensations are characteristic of hyperventilation.

Question 5

According to 14 CFR Part 91, a pilot is prohibited from acting as a crewmember of a civil aircraft within how many hours of consuming any alcoholic beverage?

Accepted Answer

8 hours

Answer

14 CFR § 91.17 states that no person may act as a crewmember of a civil aircraft within 8 hours after the consumption of any alcoholic beverage. The regulation also prohibits flying with a blood alcohol concentration of 0.04% or greater or while under the influence of alcohol.
