Human Performance & Limitations - Environmental Considerations & Survival

Question 1

How is the loudness or intensity of noise measured?

How is the pitch or frequency of noise measured?

Answer 1

Intensity (loudness) - decibles (dB)

Frequency (pitch) - hertz

Question 2

Are low pitch sounds more or less tolerable and more or less damaging than high pitch sounds?

Answer 2

More tolerable, less damaging

Question 3

Prolonged exposure to many years of the typical noise level in the cockpit of a light aircraft can cause permanent hearing loss. What is the typical noise level in the cockpit of a light aircraft?

Answer 3

Approx 85 dB

Question 4

What is the basic cause of motion sickness?

Answer 4

Continued stimulation (real or imagined) of the sensory (balance) organs in the inner ear

Question 5

Is ‘greying out’ most likley to occur at 3-4.5g or 2.5-3g applied for 5 or more seconds?

Answer 5

3 - 4.5g

Question 6

Is blood flow likely to pool in the lower abdomen and legs with increasing positive or negative ‘g’?

Does this pooling starve the blood ox oxygen or carbon dioxide?

Answer 6

Positive ‘g’, and

Starve blood of oxygen

Question 7

Name 3 potential sources of the highly roxic gas, carbon dioxide?

Answer 7

Exhaust fumes from an internal combustion engine; cigarette smoke; fire

Question 8

True or False? - The early symptoms of carbon monoxide poisoning are a possible feeling of unease, followed by an inability to think clearly, and subsequent dizziness?

Answer 8

True

Question 9

The body is effected by carbon monoxide poisoning in much the same way as it is by hypoxia (oxygen starvation), with one major difference - do the effects of carbon monoxide/ hypoxia remain after inhalation has ceased?

Answer 9

The effects of carbon monoxide remain after inhalation has ceased

Question 10

Like hypoxia, do the effects of carbon monoxide increase with a decrease or increase in altitude?

Answer 10

Increase

Question 11

How should carbon monoxide poisoning be treated?

Answer 11

Remove the sufferer from the source of carbon monoxide poisoning and take them into fresh air,

Utilise supplemental oxygen therapy where available/ practicable

Question 12

True or False? - As the concentration of carbon monoxide is increased, headaches become more severe and vision is impaired. This is rapidly followed by incapacity, loss of consciousness and death?

Answer 12

True

Question 13

True or False - breathing in fumes from fuels and lubricants usually causes headaches, nausea and drowsiness?

Answer 13

True

Question 14

True or False - Can inhalaing large amounts of Avgas produce an anaesthetic reaction in some people?

Answer 14

True

Question 15

What precuations should be taken to lessen the chnace of inhaling toxic amounts of Avgas?

Answer 15

Refuellling outside,

Promptly cleaning up accidental spills

Question 16

LIst the four priorities of survival?

Answer 16

• Protection (from exposure/ elements)
• Location/ communication,
• Water,
• Food

Question 17

In Australia’s arid centre, water for survival must be found within 30 hours or 3 days?

Answer 17

3 days

Question 18

What should be an immediate ation if forced down into the desert, jungle or sea?

Answer 18

Activate ELT

Question 19

Is survival without food possible for up to 3 days or up to 30 days?

Answer 19

30 days

Question 20

True or False - An essential rule for survival in is to rest in a shaded area until the sun goes down?

Answer 20

True
