temperature decreases at __*C per ____ ft of altitude increase
2/1000
pressure drops __Hg per _____ ft of altitude increase
1/1000

-1
what is hypoxia?
lack of oxygen to the body
symptoms of hypoxia
euphoria loss of motor skills vision impairment blue lips and fingernails fatigue loss of consciousness
factors that affect susceptibility to hypoxia
pregnancy
medication
smoking
cure for hypoxia
lowering altitude
introduce oxygen
___________ ___________ is the cause of most weather phenomena
temperature inversions
converting *C to *F
9/5 C+32
converting *F to *C
5/9(F-32)
why would you see higher temps in dry arid regions compared to desert like coastal environments
water from the coast absorbs heat in comparison to the arid region that has very little to absorb heat
how does high density altitude affect aircraft performance
air is thinner so props produce less push,
combustion is reduced,
lift is reduced
if pressure drops and you fail to adjust your altimeter setting, you are flying ________ then reported by altimeter.
lower
if pressure drops and you fail to adjust your altimeter setting, your altimeter is reading ________ than actual altitude.
higher
when climbing through 18000 ft you must
set altimeter to 29.92
pressure varies primarily with _________ and ________.
temperature, altitude
a “Low” is
pressure surrounded by higher pressure
a “high” is
pressure surrounded by lower presure
low pressure regions often have ___ flying weather
bad
high pressure regions often have ____ flying weahter
good
true altitude is referenced to
MSL
indicated altitude is
true altitude corrected for “local pressure”
