Carbon monoxide

Oxygen

Carbon dioxide

Ambient air

If REM sleep is disrupted, it will…

Take several nights sleep to recover

Disturb the circadian rhythm

Be made up by a longer sleep the next night

Be made up the next night at the expense of the slow wave sleep

How should decompression sickness be treated if encountering during flight?

Reduce the cabin pressure

By using blood thinning drugs

Place the individual on 100% oxygen if available to reduce the nitrogen in the blood

By breathing into a plastic bag

When focussing on near objects the…

Shape of lens gets more spherical

Cornea gets smaller

Shape of lens gets flatter

Pupil gets larger

The amount of light which strikes the retina is controlled by the…

Ciliary body

Lens

Cornea

Pupil

During paradoxical sleep…

Rapid eye movements can be observed

The tone of the muscles is similar to that in the waking state

The rhythm of the heart is very regular

Respiration is very regular

Shortsightedness means…

The eyeball is virtually too short

Subjects start later with presbyopia than usual

Subjects need a convex lens for correction

Subjects need a combination of spherical and cylindrical lenses for correction

A sudden change from climb to straight and level flight can give you an illusion of…

Turning to the left

A nose low attitude

A nose up attitude

Turning to the right

Stages of performance decrements due to hypoxic hypoxia are…

Indifferent stage up to 6’000 ft, disturbance threshold at 12’000 ft

Reaction threshold at 6’000 ft, disturbance threshold at 22’000 ft

Critical threshold at 12’000 ft, disturbance stage above 22’000 ft

Disturbance threshold at 6’000 ft, critical threshold at 22’000 ft

Sunglasses with variable filtration (phototrope glasses)…

Are generally forbidden for pilots

Are advantageous for pilots

Can have disadvantages when used in the cockpit due to their dependence on ultraviolet light which is screened by the cockpit glass

Are ideal, as long as there are no polarisation effects

The ozone layer absorbs…

UVA better than UVB

UV radiation up to a wavelength of 400 nm completely

Trapped intestinal gases can cause severe pain. When is this the case?

More frequent when flying above 18’000 ft in a non-pressurized aircraft

Only in pressurized aircraft when flying at higher flight levels

During descent as well as during climb, when the cabin pressure altitude is exceeding 2’000 ft

At lower altitudes

Adaptation is the…

Adjustment of the crystalline lens to focus light on the retina

Change of the diameter of the pupil

Reflection of the light at the cornea

Adjustment of the eyes to high or low levels of illumination

How is haze affecting your perception?

Haze makes the eyes to focus at infinity

Objects seem to be further away than in reality

Objects will give better contrast

Objects seem to be closer than in reality

Gaseous exchange in the human body depends on:1. Diffusion gradients between the participating gases2. Permeable membranes3. Partial pressure of oxygen in the alveolus air4. Acid-base balance in the blood

Only 1 is correct

2 and 3 are false

1, 2 and 3 are correct, 4 is false

1, 2, 3 and 4 are correct

Between which components is an interface mismatch responsible for deficiencies in conceptual aspects of warning systems (Shell-Model)?

Liveware - Environment

Liveware - Hardware

Liveware - Software

Liveware - Liveware

At an altitude where the pressure is half of that at sea level a person will have to:

Breathe pure oxygen

Breathe slow to avoid hypoxia

Use supplementary oxygen

Breathe pressurized oxygen

Hypoxia will affect night vision

And causes the autokinetic phenomena

At 5'000 ft

And causes hyperventilation

Less than day vision

To prevent the "autokinetic phenomena", the following can be done:

Turn down cabin light and shake head simultaneously

Fixate the source of light, first with one eye, then with the other

Look sideways to the source of light for better fixation

Look out for additional references inside and/or outside the cockpit using peripheral vision also

The mechanism of accommodation is caused by the...

functioning of the muscles of the eye

functioning of the ciliary muscle around the lens

elasticity of the optic nerves

diameter of the pupil

The body must have an adequate concentration of glucose to serve as an energy source. Which of the following statements is correct:

The liver stores glucose and releases glycogen into the blood-stream.

If blood sugar level falls the individual may become hyperglycaemic.

Hypoglycaemia and hypoxia are closely related.

Hypoglycaemia can cause weakness and in severe cases fainting.

The ability of the lens to change its shape is called:

Adaptation

Depth perception

Accomodation

Binocular vision

Breathing 100% oxygen at 38'000 ft is equivalent to breathe ambient air at:

8'000 ft

18'000 ft

14'000 ft

10'000 ft

The momentum of gas exchange in respiration is

The excess pressure caused by inhaling.

Depending on the active transportation of nitrogen into the alveoli.

Dependent on the pressure gradient between the participating gases during respiration.

Independent from the partial pressures of the participating gases.

Illusions can often be experienced during flight. One such illusion is created by strong forward linear acceleration. This phenomenon is called:

Coriolis

Somatogravic or oculogravic

Autokinesis

Oculogyral or leans

Hypoxia affects visual performance. A pilot may:

Have a reduction of 25% in visual acuity at 8'000 ft AGL

Get colour blindness accompanied by severe headache

Be unable to maintain piercing vision below 5'000 ft AGL

Get blurred and/or tunnel vision
