When suffering from an infection of the Middle Ear as a result of a cold, you may be affected by:
a) Perceptive Deafness
b) Conductive Deafness
The trend in aeroplane loss rate over the last three decades seems to be related to:
Someone who has anaemia has:
not enough functional haemoglobin.
What aeroplane equipment , when introduced in the 1980s, contributed to a substantial decrease in hull loss rates?
In the case of fire in flight most fatalities are caused by:
Suffocation from fumes caused by aircraft furnishing and wiring.
What aircraft equipment marked a substantial decrease in hull loss rates in the eighties?
When staring at an isolated light at night, the light may appear to:
a) vary in intensity
The function of the Eustachian tube is to equalise the pressure between the:
middle ear and the external atmosphere.
What is the basic component of the nervous system?
the nerve cell, more correctly known as a neurone.
Typical cabin pressurization systems in the cruise at high level will maintain a cabin pressurization of approximately:
6000 to 8000ft.
While carrying out a steady turn, a pilot turns around quickly to talk to another crew member. The pilot may experience:
a) Motion Sickness
b) Coriolis Effect
At high altitude with little or no cloud, the eyes tend to focus at a distance of:
a) 2 metres
b) 20 metres
The blood supply to allow the heart itself to work as a muscle is through the:
Coronary artery and vein.
Light levels at high altitude can be dangerous because they:
a) contain damaging UV and blue light.
b) enlarge the blind spot in the eye because of the intensity of the blue and UV light.
contain damaging UV and blue light.
In order to reduce the risk of coronary artery disease, exercise should:
double the resting heart rate for at least 20 minutes, three times a week.
Angular accelerations are perceived by:
a) the otoliths
b) the semicircular canals
the semicircular canals.
The normal range of blood pressure for a young healthy adult is:
Systolic 120mmHg and Diastolic 80 mm Hg.
A blocked eustachian tube can particularly:
cause severe pain during a descent.
As a cause of accidents, the human factor:
is cited in approximately 70 - 80 % of aviation accidents.
a physical condition caused by a lack of oxygen to meet the needs of the body tissues, leading to mental and muscular disturbances, causing impaired thinking, poor judgement and slow reactions.
Having given blood, a pilot should not fly for a period of:
a) 48 hours
b) 24 hours
Any prolonged exposure to noise in excess of 90 db can result in:
Noise induced hearing loss. (NIHL)
Anthropometry is the study of:
a) human working conditions
b) human measurement
With regard to alcohol:
Even a small amount will affect performance.
Body temperature is at a _______ of ________ at _______:
a) Minimum, 36.2° 0500 LMT
b) Maximum 36.9° 1800 UTC
Minimum, 36.2° 0500 LMT.
The function of the retina is:
a) to convert light into meaningful information
b) to convert light into electrical impulses
to convert light into electrical impulses.
Equalization of pressure is limited between the middle ear and the ambient, when:
the Eustachian tube is blocked.
A sudden increase in heart and respiration rates, which occurs in response to a sudden and unexpected stimulus, is produced by the activity of the sympathetic nervous system and release of adrenaline. This is known as the:
“fight or flight” response.
A rapid descent from 30 000 to 20 000 ft will cause no discomfort in the middle ear, whereas, a rapid descent from 10 000 ft to 5000 ft can cause great distress, because:
The change in barometric pressure in the latter situation is much greater.
