Flight PhysiologyCharles' Law - ANS-V1/T1=V2/T2
the law that states that for a fixed amount of gas at a constant pressure, the volume of
the gas increases as the temperature of the gas increases and the volume of the gas
decreases as the temperature of the gas decreases
Boyle's Law - ANS-A principle that describes the relationship between the pressure and
volume of a gas at constant temperature.
Physiologic Zones of the Atmosphere• - ANS-Physiologic Zones of the
Atmosphere•Physiologic Zone or the Efficient Zone•Physiologic Deficient Zone•Partial
Space Equivalent Zone•Total Space Equivalent ZonePhysiologic Zone•Sea level to
approximately 12,000 feet•The human body is adapted in this zone•Barometric pressure
drops from approximately 760 mm Hg to 485 mm Hg in this zone•Zone where
non-pressurized aircraft operate safely•Problems may develop in individuals who are
exposed to higher altitudes than they are normally exposed if they-Remain at the
altitude for prolonged periods-Exert themselvesPhysiologic Deficient Zone•12,000 to
50,000 feet•Most commercial aviation occurs in this zone•Human survival in this zone
depends on pressurized cabins and/or supplemental oxygen•Barometric pressure drops
to 87 mm Hg in this zone
Physiologic Deficient Zone• - ANS-12,000 to 50,000 feet•Most commercial aviation
occurs in this zone•Human survival in this zone depends on pressurized cabins and/or
supplemental oxygen•Barometric pressure drops to 87 mm Hg in this zone
Partial Space Equivalent Zone• - ANS-Partial Space Equivalent Zone•Because of the
reducing atmospheric pressure, hypoxia is a problem during ascent without an artificial
atmosphere 50,000 feet to 120 miles•Similar to space•Pressurized suits required
•Changes in gravity affect the bodyTotal Space Equivalent Zone•Above 120
miles•Artificial atmosphere/pressure suits mandatory for life•Weightlessness
