Aeromedical: TC 3-04.93 (Questions & AccurateAnswers)
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

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
