SPC Aeromedical Factors 3

Question 1

Which physical symptom is MOST commonly associated with hyperventilation in flight?

Accepted Answer

Tingling sensations and muscle spasms

Answer

Hyperventilation causes a drop in blood CO2, leading to respiratory alkalosis which produces tingling, numbness, and muscle cramping.

Question 2

What is the recommended in-flight treatment for a pilot who is hyperventilating?

Accepted Answer

Slow the breathing rate and talk aloud or breathe into a bag

Answer

Consciously slowing breathing—or talking aloud to force a normal rhythm—restores CO2 balance and relieves hyperventilation symptoms.

Question 3

A pilot notices a faint smell of exhaust in the cockpit. The BEST immediate action is to:

Accepted Answer

Close all vents, don oxygen if available, and land as soon as practicable

Answer

Exhaust odor suggests possible CO infiltration; pilots should close heat/vents, use oxygen if available, and land promptly before impairment worsens.

Question 4

Under FAA regulations, pilots must use supplemental oxygen for flights above 14,000 feet MSL for periods of:

Accepted Answer

The entire time at that altitude

Answer

FAR 91.211 requires that each required pilot flight crewmember use oxygen at all times when flying at cabin pressure altitudes above 14,000 feet MSL.

Question 5

Which factor does NOT typically contribute to an increased susceptibility to hypoxia?

Accepted Answer

Physical fitness

Answer

Being physically fit does not increase hypoxia susceptibility; smoking, anemia, and residual alcohol all reduce the blood's effective oxygen-carrying capacity.
