FLIGHT PHYSIOLOGY TEST 2 QUESTIONS
WITH 100% CORRECT ANSWERS
Which of the following conditions will lead to an individual feeling they are too high fro
the approach, prompting them to make a low approach? - Answer-a narrower than
normal runway
According to human physiology, above what altitude is supplemental oxygen considered
necessary to maintain humans with adequate oxygen levels for peak daytime
performance? - Answer-10,000 ft
When flying an approach to a runway down-sloping away from your approach, what
common error would you expect to see as a result of the visual illusion? - Answer-you
would see an individual make the approach too high
What actions should you follow immediately after a rapid decompression at 35,000 feet
altitude? - Answer-get yourself on oxygen immediately
Which statement regarding strategies to manage fatigue is accurate? - Answer-sleep
quality can be influenced by you environment
Which of the following aspects of flight would not affect the effective performance time
of an individual exposed to altitudethe amount of time spent pre-breathing ******* -
Answer-the amount of time spent pre-breathing
The purpose of prebreathing 100% oxygen prior to altitude exposure is to... - Answer-
decrease nitrogen levels
Hyperventilation causes which of the following changes in the body - Answer-decreased
carbon dioxide levels
What causes vasodilation? - Answer-heat
Which illusions is most likely to result when a pilot enters instrument conditions while
accelerating - Answer-somatogravic illusion
Drinking sugary drinks dehydrates rather than hydrates (true or false) - Answer-true
What does your brain need to fight fatigue? - Answer-down-time
, How many Commercial Aircraft Incidents were in 2014? - Answer-141
Average number of Commercial aircraft incidents per year? - Answer-55
How does pressurization work? - Answer-aircraft's atmosphere maintains a higher
pressure (lower Pressure altitude) than flight altitude
What is the main purpose of pressurization ? - Answer-- protect aircraft occupants from
the physiological affects of flight
-protect against HYPOXIA and Decompression Sickness
Types of Cabins - Answer-Sealed
- for extreme high altitudes
- carry own regulated and limited supply of gases
Pressurized
- forcing ambient air into the cabin to regulate environment
Methods of Pressurization - Answer-Isobaric
- constant cabin altitude
Isobaric Differential
- cabin altitude varies with flight altitude
Factors that control rate and time of decompression...? - Answer-Size of cabin
Size of opening
Pressure differential
Flight altitude
Types of decompression - Answer-Slow
- >10 seconds, popping of ears/mild hypoxia, very dangerous
Rapid
- 1-10 seconds, half of normal Effective performance time, cause of no deaths since
1999
- 80% of pilots with no R.D. experience wait up to 15 seconds for responding properly
Explosive
- <1 second, with 10 psi pressure change
Where is the safest place to sit on airplane during a crash? **** - Answer-there is none
How many G's can a healthy human take without using straining maneuvers or a G-
suit? *** - Answer-4-6
How much less impact energy is felt when I decrease ground speed from 30 kts to 20
kts?**** - Answer-less than half the impact force
