PPL PPL Pilot Health and Human Factors 1 — Questions and Answers
Question 1: What does the acronym IMSAFE help a pilot evaluate before flight?
- Aircraft airworthiness before dispatch
- Personal fitness via Illness, Medication, Stress, Alcohol, Fatigue, and Emotion/Eating (Correct answer)
- Weather conditions along the route
- Fuel and equipment requirements
Correct answer: Personal fitness via Illness, Medication, Stress, Alcohol, Fatigue, and Emotion/Eating
IMSAFE is a personal fitness checklist covering Illness, Medication, Stress, Alcohol, Fatigue, and Emotion/Eating to help pilots honestly assess their readiness to fly.
Question 2: How many hours before acting as pilot in command must a pilot refrain from consuming alcohol per FAR 91.17?
- 4 hours
- 8 hours (Correct answer)
- 12 hours
- 24 hours
Correct answer: 8 hours
FAR 91.17 prohibits flying within 8 hours of consuming any alcohol — commonly remembered as the '8 hours bottle to throttle' rule.
Question 3: What is spatial disorientation in aviation?
- Getting lost during cross-country navigation
- A false sense of aircraft attitude caused by conflicting sensory inputs, most dangerous in IMC (Correct answer)
- Vertigo caused by rapid altitude changes in turbulence
- Confusion due to hypoxia symptoms
Correct answer: A false sense of aircraft attitude caused by conflicting sensory inputs, most dangerous in IMC
Spatial disorientation occurs when the vestibular and visual systems provide conflicting information about aircraft attitude, causing the pilot to feel a false sense of motion or bank.
Question 4: What makes hypoxia particularly dangerous to pilots?
- It causes immediate loss of consciousness
- It impairs judgment and performance while the pilot may feel fine and be unaware of their own impairment (Correct answer)
- It only affects pilots who are physically unfit
- It causes severe headache as an immediate warning
Correct answer: It impairs judgment and performance while the pilot may feel fine and be unaware of their own impairment
Hypoxia is insidious because it degrades the pilot's ability to think clearly and make decisions while simultaneously impairing the self-awareness needed to recognize the problem.
Question 5: What are the effects of carbon monoxide (CO) poisoning on a pilot?
- Increased alertness and reaction time
- Headache, dizziness, and impaired judgment that can be mistaken for fatigue (Correct answer)
- Immediate hypoxia symptoms with visible blue lips
- No effect in a cockpit with functioning ventilation
Correct answer: Headache, dizziness, and impaired judgment that can be mistaken for fatigue
CO from exhaust leaks binds to hemoglobin far more readily than oxygen, causing subtle impairment including headache and confusion that pilots often attribute to fatigue.
Question 6: What is 'get-there-itis' in aviation?
- A condition causing pilots to rush the preflight inspection
- A hazardous attitude where goal-fixation causes a pilot to continue despite unsafe conditions (Correct answer)
- A type of disorientation experienced during final approach
- The urge to return to the home airport as quickly as possible
Correct answer: A hazardous attitude where goal-fixation causes a pilot to continue despite unsafe conditions
Get-there-itis is a dangerous mindset where excessive fixation on reaching a destination leads pilots to rationalize or ignore hazardous weather, fatigue, or mechanical concerns.
