Accepted Answer

rods in the retina

Answer

cones alone

Answer

the lens alone

Answer

the optic disc, where there are no light-sensitive receptors

Question 3

Which statement about spatial disorientation is correct for a PPL(A) pilot?

Question 5

A passenger develops mild nausea from turbulence, consistent with motion sickness and with no other emergency signs. Which action can help?

Accepted Answer

Provide cool fresh air where practicable and fly smoothly, avoiding unnecessary manoeuvres.

Answer

Increase head movements and use abrupt changes of bank.

Answer

Close fresh-air vents and make steeper turns.

Answer

It is the impartial assessment of evidence against the original plan.

Answer

It automatically disappears when a pilot has a valid licence.

Question 7

Which statement about short-term-memory retention without rehearsal is correct?

Question 21

What is the correct operational meaning of fatigue?

Accepted Answer

It reduces alertness, judgement and performance

Answer

Motivation alone reliably removes the effects of sleep loss.

Answer

It always improves reaction speed during an emergency.

Answer

Question 22

Why can a pilot become hypoxic at altitude even when breathing faster?

Accepted Answer

Reduced oxygen partial pressure limits oxygen loading in the lungs; compensation is limited and varies between individuals.

Answer

The percentage of oxygen in dry air always falls to zero above 12 000 ft.

Answer

Breathing faster automatically restores sea-level oxygen pressure at every altitude.

Answer

Hypoxia is caused only by a decrease in the percentage of nitrogen.
