FP-C practice questions
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. - ANS-C
What percentage of the the atmosphere contains Nitrogen? - ANS-78%
Gravity is: - ANS-The force created by the combined weight of all atmospheric gases upon the
surface of the earth.
Barometric pressure is: - ANS-The weight or force exerted by the atmosphere at any given
point.
(Physiologic) Efficient Zone - ANS-Sea level to 10,00 feet
(physiologically) Deficient Zone - ANS-10,000 to 50.000 feet
Space equivalent zone - ANS-50,000 to 250,000 feet
Space - ANS-> 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 - ANS-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 - ANS-B. Charles's law
Positive G forces - ANS-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 - ANS-blood pools in the upper body and may precipitate a headache. Can
occur during rapid descent, or turbulence that forces the aircraft downward rapidly.
