Flashcards in Other Aeromedical Factors - ATP Flight School Deck (19)
How do pilots obtain medical certificates?
By scheduling an examination by an Aviation Medical Examiner (AME).
At what point in a flight student's course of training is a medical required?
The student's first solo flight.
What class of medical should a student pilot get?
The highest class they expect to need in their aviation career.
How can a pilot with a possible medical deficiency get a medical certificate?
The special issuance process. They may have to submit additional documentation, and the resulting medical may have a shorter duration or certain limitations.
What is a SODA?
Statement of Demonstrated Ability - a waiver issued to a pilot who can prove, through ground or flight testing, that their medical deficiency does not adversely affect flight safety.
What is hyperventilation?
Excessive rate and depth of respiration, leading to abnormally low levels of carbon dioxide in the blood.
In what situations would a pilot most likely suffer from hyperventilation?
Unexpected stressful situations or flying at higher altitudes.
What are common symptoms of hyperventilation?
Lightheadedness, feeling of suffocation, drowsiness, tingling extremities, hot and cold sensations, muscle spasms, unconsciousness.
What should a pilot do if they recognize they are experiencing hyperventilation?
Consciously slow their breathing rate, and breathe less deeply. Talking aloud or breathing into a paper bag helps to regulate breathing rate. Symptoms should disappear in a few minutes.
What might happen to a pilot who doesn't recognize they are hyperventilating?
Symptoms could increase their stress level and lead to even worse hyperventilation.
What is the relationship between hypoxia and hyperventilation?
Early symptoms are similar, and they can occur at the same time. Slowing down breathing to treat hyperventilation won't help if the real issue was hypoxia.
Why is carbon monoxide poisonous?
CO binds to the hemoglobin in blood 200 times more easily than oxygen, leading to hypemic hypoxia.
What are common symptoms of CO poisoning?
Headache, blurred vision, dizziness, drowsiness, loss of muscle power.
What is the most common source of CO poisoning in light aircraft?
Cracks in the heater manifold allowing exhaust fumes to escape into the cabin.
What should a pilot do if they suspect CO poisoning?
Turn off the heater, open all fresh air vents and windows, use supplemental oxygen, terminate the flight.
What is dehydration?
A critical loss of water from the body.
What are common causes of dehydration for pilots?
Hot/humid flight lines and cockpits, dry high altitude conditions, excessive caffeine consumption (since caffeine is a diuretic), restricting fluid intake to avoid urination
What are common symptoms of dehydration?
Fatigue, dizziness, weakness, nausea, tingling hands and feet, abdominal cramps, extreme thirst
