Lesson 23
Which statement best defines hypoxia
A state of oxygen deficiency in the body. (Causes lack of clear thinking, fatigue, euphoria and unconsciousness)
Effects of carbon monoxide poisoning include...
Dizziness, blurred vision, and loss of muscle power. (Also headaches and drowsiness)
What effect does haze have on the ability to see traffic or terrain features during flight?
All traffic or terrain features appear to be farther away than their actual distance. (Which would also make pilot fly lower approach)
What preparation should a pilot make to adapt the eyes for night flying?
Avoid bright white lights at least 30 minutes before the flight.
Pilots are more subject to spatial disorientation if...
Body signals are used to interpret flight attitude.
When a stressful situation is encountered in flight, an abnormal increase in the volume of air breathed in and out can cause a condition known as
hyperventilation
Rapid or extra deep breathing while using oxygen can cause a conditions known as...
hyperventilation (occurs when too much carbon dioxide leaves body and too much oxygen is retained)
Pilots are more subject to spatial disorientation if...
Visual cues are taken away, as they are in instrument meteorological conditions (IMC).
If a pilot experiences spatial disorientation during flight in a restricted visibility condition, the best way to overcome the effect is to
rely upon the aircraft instrument indications (also the sight of the horizon)
A pilot experiencing the effects of hyperventilation should be able to restore the proper carbon dioxide level in the body by
slowing the breathing rate, breathing into a paper bag, or talking aloud
A lack of orientation with regard to the position, attitude, or movement of the aircraft in space is defined as
spatial disorientation
A state of temporary confusion resulting from misleading information being sent to the brain by various sensory organs is defined as....
spatial disorientation
The danger of spatial disorientation during flight in poor visual conditions may be reduced by
Having faith in the instruments rather than taking a chance on the sensory organs.
What are the 4 types of hypoxia
Histotoxic, hypoxia, hypemic, and stagnant hypoxia
The best method to use when looking for other traffic at night is to
Look to the side of the object and scan slowly.
Large accumulations of carbon monoxide in the human body result in
Loss of muscular power.
The illusion associated with landing on a narrower than usual runway may result in the pilot flying a
Lower approach with the risk of striking objects along the approach or landing short (this is because the narrow rwy will make you feel higher than you actually are)
Which of the following is a correct response to counteract the feelings of hypoxia in flight?
Promptly descend to a lower altitude (or supplemental oxygen if equipped)
What is the most effective way to use the eyes during night flight?
Scan slowly to permit off center viewing.
A pilot should be able to overcome the symptoms or avoid future occurrences of hyperventilation by...
Slowing the breathing rate, breathing into a bag, or talking aloud.
A pilot making a blood donation in order to help a sick associate should be aware that for several weeks
Sufficient oxygen may not reach the cells in the body
Which technique should a pilot use to scan for traffic to the right and left during straight and level flight?
Systematically focus on different segments of the sky for short intervals.
Which is a common symptom of hyperventilation?
Tingling sensations (also lightheaded ness, suffocation, drowsiness, and coolness)
Which would most likely result in hyperventilation?
Emotional tension, anxiety, or fear. (Causes increase in breathing rate)
What is a correct response if an exhaust leak were to be detected while in flight?
Open air vents or windows. (Also turning off the heater and/or using supplemental oxygen)
Susceptibility to carbon monoxide poisoning increases as
altitude increases (due to less oxygen available)
