1. The composition of the atmosphere from sea level to about 70,000 ft retains proportions of:
50% Nitrogen, 40% Oxygen, 10% other gases.
78% Oxygen, 21% Nitrogen, 1% other gases.
21% Oxygen, 78% Nitrogen, 1% other gases.
82% Nitrogen, 17% Oxygen, 1% other gase.

2. Oxygen is required by the human body to:
clear the blood of impurities produced in the body.
derive energy from the food by chemical oxidation.
produce carbon dioxide to maintain the correct acidity of the blood.
to assure the conversion of fats and proteins to carbohydrates required for tissue regeneration.

3. Gas exchanges between the air and blood takes place:
through the mucous lining of the trachea and bronchi.
between the interior of the alveoli and the capillaries on the alveoli.
from the whole surface of the lungs via the fluid in the thoracic cavity.
by means of the pulmonary artery, linking the lungs directly to the heart.

4. Oxygen is transported in the blood:
dissolved in the plasma.
in the white blood cells in chemical combination with haemoglobin.
as microscopic bubbles linked to blood platelets.
in combination with haemoglobin in the red blood cells.

5. An individual who is short of oxygen may try to compensate by increasing the rate and depth of breathing. This process is called:
hypoxic compensation.
presbycusis.
hyperventilation.
carbonic dysrhythmia.

6. The free running circadian rhythms exhibits a periodicity of about:
23 hours.
24 hours.
26 hours.
25 hours.

7. 'Slow wave sleep' occurs:
during low voltage high frequency Delta activity.
as a person first starts to fall asleep.
sleep stage 3 and 4.
the dreaming phase of REM sleep.

8. Strengthening and organising the human memory when learning new tasks is believed to occur in:
slow wave sleep.
stage 1 and 2 sleep.
Delta activity sleep.
REM sleep.

9. The 'time of useful conciousness' for an individual exposed to an altitude of 30,000 ft is:
30 minutes.
45 to 75 seconds.
12 seconds.
2 to 3 minutes.

10. Required oxygen can be provided at 37,000 ft by breathing:
100% oxygen under pressure.
an oxygen/air mixture.
100% oxygen.
a mixture of oxygen and helium to balance the partial pressure in the lungs.

11. With a large aircraft maintaining a standard 3⁰ approach teh touchdown point will be:
at the visual aiming point.
further into the runway than the visual impact point.
short of the visual impact point.
short or long from the visual impact point depending on the slope of the runway or terrain.

12. A pilot who has been scuba diving should avoid flying:
within 36 hours of the last dive.
within 24 hours or 48 hours if a depth of 30 ft has been exceeded.
only after consultation with a doctor if a depth of 30 ft has been exceeded.
within 12 hours or 24 hours if a depth of 30 ft has been exceeded.

13. A pilot suffering from decompression sickness should:
descend to a lower level where the symptoms will disappear and continue the flight at this or lower level.
decrease the cabin pressure to relieve the symptoms.
land as soon as possible.
continue the flight at a lower altitude and carry out exercises to relieve any pains in the affected area.

14. The most common amnesia affects the:
episodic memory.
short term or working memory.
semantic memory.
echoic and iconic memory.

15. If a stimulus is expected and the response prepared, when an unexpected stimulus is received:
the prepared response is likely to be carried out.
the mind will freeze and will require a reminder from its data store before actioning the new demand.
the prepared response will be trabsfered to the long term memory store.
the mind will switch off and ignore the unexpected stimulus.

16. The area on the retina where the optic nerve receives all the information from the nerves of the retina is:
the blind spot.
the fovea.
the rod/cone intersection point.
the most sensitive part of the retina with the highest visual acuity.

17. The eye adjusts to changing light intensities by varying the diameter of the iris. This can reduce the amount of light on the retina by a factor of:
10:1
2:1
5:1
20:1

18. Following a flight that transits numerous time zones, the associated shifting of zeitgebers help resynchronisation to the new local time at the rate of:
2 hours per day.
1.5 hours per day.
3 hours per day.
4 hours per day when the shift has been eastward and 1 hour per day if westward.

19. A man is considered to be overweight if his body mass index is over:
22.
30.
25.
18.

20. The functions of the nasal passage are:
to enable the detection of possible noxious gases and trigger the body's automatic defences.
to trap harmful particles and bacteria in their mucous membranes so that they will not pass into the very delicate lung tissue.
to filter, warm and humidify air drawn in during inspiration.
to draw off a sample of the air for analysis to enable the respiratory mechanism to adjust the rate and depth of respiration.
