Aeromedical: TC 3-04.93 (Questions & Accurate
Answers)
Physiological (self-imposed) Stressors Right Ans - Drugs
Exhaustion
Alcohol
Tobacco
Hypoglycemia
Types of Hypoxia Right Ans - Hypoxic - altitude
Hypemic - CO, cigarettes
Histotoxic - alcohol
Stagnant - G maneuvers, seat belts
Physiological effects of smoking Right Ans - Loss of 20% of night vision at
SL, and physiological altitude of 5000 ft
The only significant effect of hypoxia in the indifferent stage occurs at:
Right Ans - 4000 ft. Reduction in night vision.
Spatial Disorientation Right Ans - Is an individual's inability to determine
his position, attitude, and motion relative to the earths surface.
3 types of Spatial Disorientation Right Ans - Type 1 - Unrecognized, Type 2
- recognized, Type 3 - incapacitating.
Prevention of Spacial Disorientation Right Ans - Never fly without visual
reference points
Never Fly VMC in IMC
Avoid fatigue, hypoglycemia, anxiety, hypoxia (HASH) Trust your instruments
Treatment of Spacial Disorientation Right Ans - Refer to the instruments
Delay intuitive actions
Transfer the flight controls
During flight the what system is the most reliable? Right Ans - The visual
system
, The proprioceptive system is closely associated with: Right Ans - The
vestibular system. (And a lesser degree the visual system)
Fatigue Right Ans - State of feeling tired, weary or sleepy that results from
prolonged mental or physical work, extended periods of anxiety, exposure to
harsh environments, or loss of sleep. Boring or monotonous tasks can increase
fatigue.
3 types of fatigue Right Ans - Acute
Chronic
Motivational (burnout)
List 3 Somatogyral Illusions (vestibular illusions) Right Ans - The leans,
graveyard spin, coriolis illusion. Vestibular illusions caused by angular
acceleration stimulating the semicircular canals.
List 3 Somatogravic Illusions (vestibular illusions) Right Ans - Oculogravic,
elevator, oculoagravic. Vestibular illusions caused from changes in linear
acceleration or gravity that stimulates the otolith organs.
To prevent spatial disorientation aviators should: Right Ans - Never fly
without visual reference points
Never fly both VMC and IMC at the same time
Avoid stressors
Trust the instruments
If spatial disorientation occurs, aviators should: Right Ans - Refer to
instruments and develop a good cross check
Delay intuitive actions long enough to check vis/instr
Transfer control to the other pilot
4 stages of hypoxia hypoxia Right Ans - Indifferent - 0-10k - 90-98%O2
Compensatory - 10-15k - 80-89%
Disturbance - 15-20k - 70-79%
Critical - 20-25k - 60-69%
Prevention hypoxic hypoxia Right Ans - Limit time at altitude
Use supplemental oxygen
Pressurize the cabin
