Which of the following statements is correct regarding gases as altitude increases ?
A. The percentages and total pressure of gases are increased
B. The percentages of gases increase as the total gas pressure decreases
C. The percentages of gases are unchanges, but the total pressure of the gases decreases.
D. The percentages of gases decrease and the total gas pressure remains the same. - ANSWER C
What percentage of the the atmosphere contains Nitrogen? - ANSWER 78%
Gravity is: - ANSWER The force created by the combined weight of all atmospheric gases upon the
surface of the earth.
Barometric pressure is: - ANSWER The weight or force exerted by the atmosphere at any given point.
(Physiologic) Efficient Zone - ANSWER Sea level to 10,00 feet
(physiologically) Deficient Zone - ANSWER 10,000 to 50.000 feet
Space equivalent zone - ANSWER 50,000 to 250,000 feet
Space - ANSWER > 250.000 feet
The development of gas bubbles within the body at high altitudes is best explained by:
A. Boyle's law
B. Charles's law
C. Henry's law
D. Dalton's law - ANSWER C. Henry's law
During a rapid decompression, the rapid change in temperature is best explained by:
A. Boyle's law
B. Charles's law
C. Henry's law
D. Dalton's law - ANSWER B. Charles's law
Positive G forces - ANSWER Blood pools in the lower extremities increasing intravascular pressures and
stagnant hypoxia. Can occur during rapid ascent, or turbulence that forces the aircraft upward rapidly.
Negative G forces - ANSWER blood pools in the upper body and may precipitate a headache. Can occur
during rapid descent, or turbulence that forces the aircraft downward rapidly.
