Which of the following describes the symptoms of Hypoxia?
Hypoxia is caused by lack of oxygen going through your body, including the brain, causing light-headedness or headache, tingling in outer limbs, cyanosis and increased breathing rate.
Roughly how long does it take for the human body to process one unit of alcohol?
A light aircraft is flying at 100kts and a military jet is flying at 350kts. Approximately how much time do the pilots have to avoid a collision on a head-on course with only 5km between them?
Closing speed is the combined speeds: 100 + 350 = 450kts, 1 NM = 1.852 km so 5km : 1.852 = 2.7NM Time = distance : speed, 2.7NM : 450kts = 0.006 hour, 0.006 x 60 = 0.36 minutes, 036 x 60 = 21.6 seconds
How long does it take the eye to fully adapt to the dark?
The rods are most important for night vision which can take up to 30 minutes to adjust to the dark. Cones are more sensitive to light intensity and lose their effectiveness in the darkness.
The peripheral, central and autonomic are what type of system within the body?
The peripheral and central systems are the main nervous systems, the autonomic system is part of the peripheral nervous system.
What is the purpose of the respiratory system?
Exchange of gases, especially carbon dioxide and oxygen, is the most important function of the respiratory question.
Which of the following best describes the autonomic nervous system?
The autonomic system is part of the peripheral system and controls organs, systems and functions which are not under voluntary control.
In the ‘SHELL’ model of error management what does the ‘S’ stand for?
S = Software, H = Hardware, E = Environment, L = Liveware
Having allowed sufficient time for night vision to develop, when looking at an object beyond the aircraft the maximum visual acuity can be achieved by looking:
Cones are situated in the middle of the retina, whilst rods, which are most important for night vision, are situated on the outer sides of the retina, so looking straight at an object at night does not give you maximum vision.
Why should a pilot not fly when suffering from a cold?
When you have a cold the eustachian tube between the middle air and the nasal passage can be blocked. When changing altitudes and pressures in the aircraft, a blocked eustachian tube can cause barotrauma.
Sensory information:
The sensory memory only stores the incoming sensory information for a brief moment before it gets replaced with other information, unless the incoming information is processed further.
16. The initial signs of the onset of hypoxia include:
In the early stages of hypoxia a person may only feel euphoric or experience mood swings. As altitude increases and oxygen levels drop, physical movements become more difficult and eventually lead to unconsciousness.
