correct answer ✅-1.98 degrees Celsius per 1,000 feet
p. 2-2
What are the Physiological Zones of the Atmosphere? -
correct answer ✅1. Efficient Zone (Sea Level to 10,000 ft)
2. Deficient Zone (10,000 to 50,000 ft)
3. Space Equivalent Zone (50,000 ft to outer edge of atmosphere)
p. 2-7
What are the types of Spatial Disorientation? Explain each. -
correct answer ✅1. TYPE I (UNRECOGNIZED)-an aviator does not
perceive any indication of SD or think anything is wrong. Type I SD is
the most dangerous type of disorientation.
2. TYPE II (RECOGNIZED)-the pilot perceives a problem resulting
from SD but might not recognize it as SD.

3. TYPE III (INCAPACITATING)-the pilot experiences such an
overwhelming sensation of movement that he or she cannot orient
using visual cues or the aircraft instruments. Type III SD is not fatal
if the copilot can gain control of the aircraft.

What is the most dangerous of all vestibular illusions? -
correct answer ✅Coriolis illusions are the most dangerous of all
vestibular illusions and cause overwhelming disorientation. Causes
the pilot to experience an overwhelming head-over-heels tumbling
sensation.

What causes Somatogravic Illusions? -
correct answer ✅Somatogravic illusions are caused when changes
in gravity or linear acceleration and deceleration stimulate the
otolith organ.
