AVIT 309 FINAL PAPER 2026 QUESTIONS WITH
ANSWERS GRADED A+
◉ Atmospheric function. Answer: Provide Life Support (oxygen and
pressure. Protection from harmful effects of UV and space radiation,
thermal variations, and orbital material striking earth.
◉ FAA classifies pilots as. Answer: occupational radiation workers
◉ How do we decrease radiation risks in the aviation industry? Answer:
sunscreen/UVA protectant sunglasses. Know your exposure FAA AC
120-61A
◉ O-Zone depletion creates. Answer: 50% increase in lightning strikes,
increased storm size and activity, increased CO2
◉ gases in atmosphere. Answer: Oxygen 20.95%
Nitrogen 78.09%
Carbon Dioxide .04%
◉ What determines our ability to perform. Answer: combination of
pressure and oxygen percentage
,◉ Full acclimatization takes. Answer: 18.4 days per mile (5280), can not
acclimate above 10,000 ft
◉ Long term physiologic changes. Answer: increase in RBC mass,
mitochondria, capillaries, & arterial pressure.
◉ Short Term physiologic changes. Answer: hyperventilation, shortness
of breath, changed breathing pattern at night, increased urination
◉ What is barometric pressure. Answer: the pressure due to the weight
of the gases attracted to earth. Decreases as we go to altitude
◉ Temp lapse rate. Answer: 2 degree C per 1000 ft
◉ Isothermic layer of stratosphere. Answer: -55 C or 67 F
◉ water vapor with altitude. Answer: decreases
◉ Troposphere. Answer: SL to 350 (average), standard temperature
lapse rate, most weather events occur here, ranges from 23,000 ft to
56,000 ft
◉ Where is the jet stream? Answer: Tropopause
, ◉ Stratosphere. Answer: FL 350 to 50 miles altitude, common cruise
altitude, extremely cold, isotherm layer at 67F
◉ Ionosphere. Answer: Blocks radiation through the Van Allen Belts
◉ Exosphere. Answer: 1200 miles, space
◉ Physiologic Divisions. Answer: 1. Zone of Normal adaptation-
healthy people. Located up to 10,000 ft msl, we adapt to increase oxygen
delivery. Does not impair performance.
2. Zone of physiologic deficiency- 10,000 feet to 50,000, unable to adapt
and function normally. Conventional life support equipment is needed to
support normal functioning.
3. Space equivalent zone- special life support equipment is needed
◉ Gas Laws. Answer: (boyle's law) subjected to pressure.
(charles' law) subjected to heat.
(henry's law) dissolved in a solution.
