AVIT 309 BLOCK 1 QUESTIONS & ANSWERS
Who are the three professors? - answer -tom zeidlik, steve martin, and bob kunze.
Atmospheric functions. - answer -provide life support (oxygen and pressure)
Protection from harmful effects of:
-uv and space radiation
-thermal variation
-orbital material striking earth
Loci accident between 1991 - 2010? - answer -unintentional stalls occurred in 31 of 71
accidents.
2/3 of accidents happened during what part of flight? - answer -takeoff, approach, or
landing under 1,000 feet.
Composition of the atmosphere? - answer -oxygen (o2): 21%... Life support
Nitrogen (n2): 78%... Inert but significant
Carbon dioxide (co2): respiration byproduct
As we ascend what two factors determine our ability to preform? - answer -pressure
and oxygen percentage.
Full physiological adaption to altitude takes _______ per ________ altitude? - answer -
18.4 days / mile (5280 ft)
Barometric pressure definition? - answer -the pressure due to the weight of the gases
attracted to earth.
Barometric pressure __________ as we go to altitude? - answer -decreases.
Temperature lapse rate
________ centigrade per 1000 feet
________ fahrenheit per 1000 feet - answer -2.0 centigrade
3.5 fahrenheit
Troposphere altitude? - answer -sl to fl350.
Stratosphere altitude and average temperature? - answer -fl350 to 50 miles.
Isotherm layer at -67 f
Ionosphere does what? - answer -blocks radiation through the van allen belts.
Exosphere? Altitude? - answer -space / 1200 miles.
, Zone of normal adaptation? - answer -10,000 msl and below.
Zone of physiologic deficiency? - answer -10,000 feet to 50,000 feet.
Can never adapt to function normally
Space equivalent zone what gear is needed? - answer -full pressure suit, sealed cabin,
and emergency pressurization system.
Boyle's law? - answer -pressure and volume are inversely proportional.
Charles' law? - answer -if gas is heated, then the volume will increase.
If volume is stable, then pressure increases.
Henry's law? - answer -considered rapid decompression.
Law of gaseous diffusion? - answer -gas will diffuse from high pressure to low pressure
naturally.
Dalton's law? - answer -each component of a gas contributes to the total pressure.
What does ventilation do for your body? - answer -bring air into the lung.
What does respiration do for your body? - answer -gas exchange across the alveolar
barrier.
3 steps air goes through before it enters your lung? - answer -filtered, warmed, and
humidified.
Average rate someone breath's at? - answer -12 - 20 breath's per minute.
Primary and secondary controls of respiration? - answer -primary: brain monitors
carbon dioxide
Secondary: aortic bodies monitor oxygen saturation in blood & csf
3 steps of - answer -ventilation, diffusion, oxygen transport, and utilization
Alveolar environment includes? - answer -1. Oxygen
2. Pressure
3. Water vapor given off by living tissue
4. Carbon dioxide (co2)
What is homeostasis? - answer -condition for optimum cellar and bodily function.
Define hypoxia? - answer -oxygen deficiency in blood, body tissue, and cells sufficient
to cause impairment of function.
