Question 118-15 : The metabolisation of alcohol ?
Is a question of time
.alcohol is a toxin that must be neutralized or eliminated from the body alcohol metabolism is a complex process with large individual variations related to absorption distribution and elimination .the liver metabolizes alcohol at a rate of 0 015% per hour
Question 118-16 : What does not impair the function of the photosensitive cells ?
High speed
.the human retina has approximately 5 million cones and 120 million rods .signals from the rods and cones converge on ganglion and bipolar cells for preprocessing before they are sent to the lateral geniculate nucleus at the 'center' of the retina the point directly behind the lens is the fovea which contains only cone photoreceptor cells this is the region capable of producing the highest visual acuity .oxygen deficiency acceleration positive or negative and poisons cause disturbances
Question 118-17 : The fovea is ?
The area of best day vision and no night vision at all
Question 118-18 : In order to completely resynchronise with local time after zone crossing circadian rhythms require ?
Less time when flying from east to west
Question 118-19 : The retina of the eye ?
Is the light sensitive inner lining of the eye containing the photoreceptors essential for vision
Question 118-20 : Which force s affect s the otoliths in the utriculus and sacculus ?
Gravity and linear acceleration
.the utricle is sensitive to a change in horizontal movement .the saccule gives information about linear acceleration such as when in an elevator
Question 118-21 : Flying a coordinated level turn will ?
Make the body's pressure receptors feel an increased pressure along the body's vertical axis
Question 118-22 : Which sensations does a pilot get when he is rolling out of a prolonged level turn ?
Turning in the opposite direction
Question 118-23 : How can a pilot overcome vertigo encountered during a real or simulated instrument flight .1 establish and maintain an effective instrument cross check .2 always believe the instruments never trust your sense of feeling .3 ignore arising illusions .4 move the head sidewards and back and forth to ?
1 2 and 3 are correct
Question 118-24 : A large number of medical preparations can be bought without a doctor's prescription in relation to using these preparations which of the following is correct ?
A pilot using any of these preparations should get professional advice from an aviation medical specialist if he intends to fly and self medicate at the same time
Question 118-25 : The total pressure of a mixture of gases is equal to the sum of the partial pressures of the gases in the mixture this is ?
Dalton's law
.dalton's law states that the pressure of a mixture of gases is the sum of the partial pressures of its constituents .for information the amount of oxygen transfered into the blood in the alveoli depends on the partial pressure of oxygen and when the partial pressure of oxygen is too low we become hypoxic
Question 118-26 : Carbon monoxide is always present in the exhaust gases of engines if a pilot is exposed to carbon monoxide which of the following responses is correct ?
A short exposure to relatively high concentrations of carbon monoxide can seriously affect a pilot's ability to operate an aircraft
Question 118-27 : When stopping the rotation of a spin we have the sensation ?
That we are starting a spin in the opposite direction
Question 118-28 : The human ear is capable of perceiving vibrations between the frequencies ?
20 20000 hz
Question 118-29 : The intensity of a sound is measured in ?
Decibels
Question 118-30 : The ozone layer is situated in the ?
Stratosphere
Question 118-31 : The barometric pressure has dropped to 1/2 of the pressure at sea level at ?
18 000 feet
.at mean sea level standard pressure is 1013 hpa.at 5000 ft = 850 hpa.at 10000 ft = 700 hpa.at 18000 ft = 500 hpa.at 30000 ft = 300 hpa
Question 118-32 : Which of the following laws explains bubbles of nitrogen coming out of solution in body tissues due to a decrease in atmospheric pressure ?
Henry's law
Question 118-33 : The main function of the red blood cells is ?
To transport oxygen
Question 118-34 : Altitude hypoxia when breathing ambient air should not usually occur indifferent phase ?
Below 3000 m
Question 118-35 : 'the bends' as a symptom of decompression sickness consists of ?
Pain in the joints
Question 118-36 : The type of hypoxia which occurs at altitude is a explained by ?
Dalton's law
.dalton's law tells us that the total pressure of any mixture of gases with constant temperature and volume is the sum of the individual pressures also called partial pressure of each gas in the mixture also partial pressure of each gas is proportional to that gas's percentage of the total mixture because the percentage of oxygen in the atmosphere remains constant at 21% dalton's law lets us calculate the partial pressure of the oxygen in the atmosphere at any altitude .the human body is affected by the pressure of the gases in the atmosphere the partial pressure of oxygen and to a lesser extent other gases available in the surrounding air is important in determining the onset and severity of hypoxia
Question 118-37 : Carbon monoxide a product of incomplete combustion is toxic because ?
It competes with oxygen in its union with haemoglobin
Question 118-38 : Hyperventilation causes ?
A reduction of carbon dioxide in the blood
Franck .when you hyperventilate you loose carbon dioxide from the lungs the way to treat it is to breath into a paper bag to breath back the carbon dioxide you're exhaling and to calm down
Question 118-39 : Anxiety and fear can cause ?
Hyperventilation
