Means “reduced oxygen” or “not enough oxygen.”
(a)
This is a result of insufficient oxygen available to the body as a whole. A blocked airway and drowning are obvious examples of how the lungs can be deprived of oxygen, but the reduction in partial pressure of oxygen at high altitude is an appropriate example for pilots.
Hypemic Hypoxia
Hypoxic Hypoxia
Stagnant Hypoxia
Histotoxic Hypoxia
This type of hypoxia is a result of oxygen deficiency in the blood, rather than a lack of inhaled oxygen, and can be caused by a variety of factors.
Hypoxic
Hypemic
Stagnant
Histotoxic
Which is the most common type of hypemic hypoxia?
Blood loss
CO poisoning
Anemia
Volemic Shock
This happens when the oxygen-rich blood from the lungs stopped moving. This is also called ischemia.
Hypoxic Hypoxia
Hypemic Hypoxia
Stagnant Hypoxia
Histotoxic Hypoxia
The term '________' describes the maximum time the pilot has to make rational, life-saving decisions and carry them out at a given altitude without supplemental oxygen.
Time of concsiousness
Time of relative attention
Time of useful consciousness
Time of healthy life
(a) is the excessive rate and depth of respiration leading to abnormal loss of carbon dioxide from the blood.
These are the organs found in the inner ear that sense position by the way we are balanced.
Vestibular System
Somatosensory System
Visual System
Psychosomatic Sensory System
These can result when a banked attitude, to the left for example, may be entered too slowly to set in motion the fluid in the “roll” semicircular tubes. An abrupt correction of this attitude sets the fluid in motion, creating the illusion of a banked attitude to the right.
The Leans
Coriolis Illusion
Graveyard Spiral
Somatogravic Illusion
As in other illusions, a pilot in a prolonged coordinated, constant-rate turn, will have the illusion of not turning. During the recovery to level flight, the pilot will experience the sensation of turning in the opposite direction.
The Leans
Coriolis Illusion
Graveyard Spiral
Inversion Illusion
The (a) sends signals from the skin, joints, and muscles to the brain that are interpreted in relation to the Earth’s gravitational pull.
An absence of surrounding ground features, as in an overwater approach, over darkened areas, or terrain made featureless by snow, can create an illusion the aircraft is at a higher altitude than it actually is.
Runway and terrain slopes illusion
Featureless Terrain Illusion
Water Refraction
Haze
______________ is caused by the brain receiving conflicting messages about the state of the body.
Motion Sickness
Hyperventilation
Stress
Carbon Monoxide Poisoning
(a) are drugs that reduce the body’s functioning in many areas. These drugs lower blood pressure, reduce mental processing, and slow motor and reaction responses.
(a) are drugs that excite the central nervous system and produce an increase in alertness and activity. Amphetamines, caffeine, and nicotine are all forms of this drug.
How many percent should be the weight of alcohol circulating in your blood?
less than 0.04
less than 0.05
less than 0.06
less than 0.045
______________ describes a condition characterized by a variety of symptoms resulting from exposure to low barometric pressures that cause inert gases (mainly nitrogen), normally dissolved in body fluids and tissues, to come out of physical solution and form bubbles.
Compression Sickness
Motion Sickness
Hypoxia
Decompression Sickness
This causes the eyes to relax and seek a comfortable focal distance which may range from 10 to 30 feet. For the pilot, this means looking without seeing, which is dangerous.
Nearsightedness
Colorblindness
Failure to perceived depth
Empty-field myopia
___________ can occur when the natural horizon is obscured or not readily apparent. It can be generated by confusing bright stars and city lights.
Autokinesis
False Horizon
False Peak
Mirroring
Fatigue falls into two broad categories, acute and chronic. Acute fatigue has a special type that has two main effects in performance namely, Timing disruption and Disruption of the perceptual field. What do you call this special type of acute fatigue?
(a)
