True or False. Cockpit noise interferes with communication in the cockpit, causes fatigue and, over time, can cause permanent hearing impairment?
True.
Name an occasion in the cockpit when noise may actually be an advantage?
During times of boredom/fatigue.
The maximum permissible continues exposure level to steady noise in a working environment is usually quoted as (90 dB/140 dB) for a maximum of (4 hours/8 hours)?
- 90 dB.
- 8 hours.
Task that require vigilance, concentration, calculations, and making judgements about time can be adversely affected by exposure to noise with an intensity higher than (40 dB/90 dB)?
90 dB.
Good quality headsets can lower noise levels by about (30 to 35 dB/80 to 90 dB)?
30 to 35 dB.
Loudness or intensity of noise is measured in (hertz/decibels) and pitch or frequency in (hertz/decibels)?
- Decibels.
- Hertz.
Sounds of low pitch are (more/less) tolerable than high pitched noises and (more/less) damaging to hearing?
- More.
- Less.
What is the basic cause of motion sickness?
Continued stimulation of the balance organ in the inner ear.
List three factors which may aggravate motion sickness?
- Stuffy Environment.
- Anxiety.
- Full Stomach.
- Focusing on Nearby Objects.
List three methods of combating motion sickness in flight?
- Fresh Air.
- Loosen Clothing.
- Focus on a point outside the Aircraft.
- Avoid unnecessary Head Movements.

Greying out is most likely to occur at (3 to 4.5 g/2.5 to 3 g)?
3 to 4.5 g.
Total loss of vision under a sustained load of 4.5 g to 5.5 g is called (grey out/black out)?
Black out.
Increasing degrees of Hypoxia followed by loss of consciousness are most likely (below/above) 6 g?
Above.
With increased (positive g/negative g), the blood pools in the lower abdomen and legs. This pooling drains the blood from the brain and starves it of (carbon dioxide/oxygen)?
- Positive g.
- Oxygen.
Under increased (positive/negative) g, the blood vessels within the transparent membrane covering the white of the eyes become enlarged and are visible as a red mist known as red-out?
Negative.
True or False. Hypoxia-induced unconsciousness results from the cardiovascular effects of high g?
True.
Name three sources of the highly toxic gas, carbon monoxide?
- Fire.
- Cigarette Smoke.
- Exhaust fumes from the Engine.
What are the early symptoms of carbon monoxide poisoning (3)?
- Feeling of Unease.
- Inability to think clearly.
- Dizziness.
The body is affected by carbon monoxide poisoning in the same way as it is by Hypoxia, with one major difference, explain this difference?
Oxygen immediately removes Hypoxia, however not with Carbon Monoxide.
Like Hypoxia, the effects of carbon monoxide poisoning (decrease/increase) with Altitude?
Increase.
True or False. As the concentration on carbon monoxide is increased, headaches become more severe and vision is impaired. This is rapidly followed by incapacity, loss of consciousness and death?
True.
True or False. Breathing in fumes from fuels and lubricants usually causes headache, nausea and drowsiness?
True.
If inhaled in large enough amounts, (AVGAS/fire extinguisher) fumes may produce an anaesthetic reaction in some people?
AVGAS.
What precautions should be taken to lessen the chance of inhaling toxic amounts of AVGAS (2)?
- During Refuelling.
- Quickly cleaning up any accidental spills.
List the four priorities for survival?
- Protection.
- Location.
- Food.
