AVIT 309 FINAL QUESTIONS & ANSWERS
In the process of an oxygen system pre-flight, "S" stands for? - Answer -Supply: to
make sure you have an adequate oxygen supply prior to takeoff
While in IMC, you return to the flight instruments after a distractions. You find you are in
a level turn to the left, but it feels to you that the aircraft is flying straight and level.
Based on this information, you can assume that? - Answer -When you return to straight
and level flight, you will now feel a turn to the right.
How is effective performance time influenced by a rapid decompression, as compared
to removing your oxygen mask at the same final altitude? - Answer -the effective
performance time is decreased by 1/3 to 1/2.
Why do we have a night blind spot in our vision? - Answer -The high concentration of
CONES in our fovea cannot detect low levels of light.
Which oxygen storage system is most commonly associated with passenger use during
decompressions in commercial aircraft? - Answer -chemical oxygen systems.
When flying an approach to a runway down-sloping away fro your approach, what
common error would you expect to see as a result of the illusion? - Answer -you would
see an individual make the approach too high.
What are the tree ways heat transfers from one object to another? - Answer -
convection, radiation, touch.
Pressurization systems are designed to minimize the effects of which problems? -
Answer -Hypoxia, evolved gas disorders, and trapped gas problems.
Flashover combustion (in an aircraft cabin during a fire) is initiated when combustible
gases explode. What is the source of these gases? - Answer -Fumes from heated
materials.
What is the most harmful thing to the mental health of this generation? - Answer -
illuminated rectangles.
You are flying with an individual who is very fatigued. How would you expect fatigue to
affect their performance? - Answer -fatigue can affect mood, motivation, and
communication skills in individuals.
Which of the following toxic fumes causes hypemic hypoxia? - Answer -carbon
monoxide.
, What actions should you follow immediately after a rapid decompression at 35,000 feet
altitude? - Answer -get yourself on oxygen immediately.
Hyperventilation causes which of the following changes in the body? - Answer -
decreased carbon dioxide levels.
Which of the following needs has greatest priority in a survival setting? - Answer -
Temperature regulation/shelter.
Injury pattern information can be used to? - Answer -evaluate restraint effectiveness,
determine who was in control of the aircraft at the time of impact, understand the
direction and degree of forces at the time of impact.
Which of the following aspects of flight would NOT affect the effective performance time
of an individual exposed to altitude? - Answer -the amount of time spent pre-breathing
oxygen.
Effective performance time is approximately 3-5 minutes in healthy individuals exposed
to what altitude? - Answer -25,000 feet.
What causes vasodilation? - Answer -Heat.
What is the most essential aid to a person in a survival situation? - Answer -a strong
will to live.
Which of the following conditions will lead to an individual feeling they are too high for
the approach, prompting them to make a low approach? - Answer -a narrower than
normal runway.
You are flying while congested and note a sudden pain in the side of your face and
several upper teeth on one side of your mouth during descent. Your actions should be
to? - Answer -correcting for a sinus block by ascending and/or valsalva.
Drinking sugary drinks dehydrates rather than hydrates? - Answer -true.
Which illusions is most likely to result when a pilot enters instrument conditions while
accelerating? - Answer -somatogravic.
What gas content of the blood influences the primary control of the respiratory rate in
normal humans the majority of the time? - Answer -carbon dioxide.
Which of the following problems is not directly influenced by the use of pressurized
cabins? - Answer -hyperventilation.
Ear protection works primarily to decrease noise? - Answer -intensity.
