Aeromedical (40-8)

Question 1

Spatial Disorientation

Definition, types

Answer 1

Def: Inability to determine position, attitude, motion to surface

Types:

1: Unrecognized, most dangerous
2: Recognized, but not as spatial D (ex. Leans)
3: Incapacitating, overwhelming sensation (ex. Coriolis)

Question 2

Prevention Spatial D

Treatment Spatial D

Answer 2

Prevent:
Never fly IMC/VMC
Never fly w/out reference
Avoid Stressors
Trust Instruments

Treatment (Dr. T)
Delay actions
rely on use/instruments
Transfer controls

Question 3

Sensory Systems

Answer 3

Visual (80%, reliable)
Prioprioceptive (pressure on body)
Vestibular (inner ear)

Question 4

Vestibular Illusions

Answer 4

Somatogyral
(Leans, graveyard, coriolis)

somatogravic
(oculogravic fighter ship), elevator (upward), oculoagravic (downward)

Question 5

Illusions

Answer 5

Somatogyral
Leans - Feel straight, level. Attitude shows bank.
Graveyard Spin - F/W, spin for seconds, reach equilibrium

Coriolis - Most dangerous, overwhelming disorientation in pitch and roll and yaw.
