ATPL 040 Human Performance Practice Questions - EASA ATPL Theory - Human Performance and Limitations (040) Exam - ATPL 040 Human Performance Practice Questions - EASA ATPL Theory - Human Performance and Limitations (040) Exam

Question 1

The composition of dry atmospheric air by volume is approximately:

21% oxygen, 78% nitrogen, 1% other gases 78% oxygen, 21% nitrogen, 1% other gases 50% oxygen, 50% nitrogen 33% oxygen, 66% nitrogen, 1% other gases

Correct Answer:

21% oxygen, 78% nitrogen, 1% other gases

Question 2

Even though total atmospheric pressure decreases with altitude, the percentage of oxygen in the air remains constant. Therefore, the reason a pilot becomes hypoxic at altitude is principally that:

Carbon dioxide concentration rises sharply with altitude The percentage of oxygen in the air falls below 21% The partial pressure of oxygen falls, reducing oxygen uptake in the lungs Nitrogen replaces oxygen in the alveoli

Correct Answer:

The partial pressure of oxygen falls, reducing oxygen uptake in the lungs

Question 3

A pilot flying an unpressurised aircraft at 25,000 ft suffers a complete loss of supplemental oxygen. The approximate Time of Useful Consciousness (TUC) at this altitude is:

20 to 30 minutes 3 to 5 minutes 30 to 60 seconds 9 to 12 seconds

Correct Answer:

3 to 5 minutes

Question 4

Following a rapid (explosive) decompression at high altitude, the Time of Useful Consciousness compared with a gradual loss of oxygen at the same altitude will be:

Approximately doubled Unchanged Reduced by roughly one half Increased by about 25%

Correct Answer:

Reduced by roughly one half

Question 5

One of the most insidious dangers of hypoxia is that the affected pilot:

Becomes immediately and obviously unconscious Develops severe sweating and shivering as a clear warning Feels acute chest pain warning of the onset Experiences a false sense of well-being (euphoria) and lacks insight into the impairment

Correct Answer:

Experiences a false sense of well-being (euphoria) and lacks insight into the impairment
