ATPL Human Factors Practice Questions - CASA Airline Transport Pilot Licence (Aeroplane) - Human Factors (AHUF) Exam - ATPL Human Factors Practice Questions - CASA Airline Transport Pilot Licence (Aeroplane)

Question 1

According to Dalton's law of partial pressures, as an aircraft climbs, what happens to the atmospheric pressure and the partial pressure of oxygen in the atmosphere?

The partial pressure of oxygen increases to compensate for the decrease in atmospheric density. Atmospheric pressure decreases, but the partial pressure of oxygen remains constant because the percentage of oxygen in the air does not change. Both atmospheric pressure and the partial pressure of oxygen increase due to the cooling effect of the atmosphere. Both atmospheric pressure and the partial pressure of oxygen decrease in direct proportion to altitude.

Correct Answer:

Both atmospheric pressure and the partial pressure of oxygen decrease in direct proportion to altitude.

Question 2

Which gas law states that, at a constant temperature, the volume of a gas is inversely proportional to its pressure?

Charles's Law. Henry's Law. Boyle's Law. Dalton's Law.

Correct Answer:

Boyle's Law.

Question 3

Henry's Law explains which of the following physiological conditions in high-altitude aviation?

Hypoxic hypoxia, due to the reduced partial pressure of oxygen in the alveoli. Hyperventilation, which lowers carbon dioxide levels in the bloodstream. Barotrauma in the middle ear during descent, due to gas contraction. Decompression sickness, due to nitrogen bubbles coming out of solution in body tissues.

Correct Answer:

Decompression sickness, due to nitrogen bubbles coming out of solution in body tissues.

Question 4

What is the primary cause of hypoxic hypoxia at high altitudes?

The binding of carbon monoxide to hemoglobin, blocking oxygen transport. A reduction in blood circulation to brain tissues due to high G-forces. The decrease in the partial pressure of oxygen in the inspired air. The poisoning of cellular respiratory enzymes by toxins such as alcohol.

Correct Answer:

The decrease in the partial pressure of oxygen in the inspired air.

Question 5

An aviator who is a heavy smoker or is exposed to an engine exhaust leak is highly susceptible to which type of hypoxia?

Hypoxic hypoxia. Stagnant hypoxia. Histotoxic hypoxia. Hypemic hypoxia.

Correct Answer:

Hypemic hypoxia.
