Human Factors Flashcards
Oxygen is transported by the circulating blood to the tissues of the body combined with which carrier molecule?
Hemoglobin in the erythrocytes
Some subjective symptoms of hypoxia include:
Apprehension, headache, euphoria
Useful consciousness at 40,000ft
15-30 secs
Useful consciousness at 30,000ft
45-75 secs
T/F - Hyperventilation symptoms always develop very rapidly
False
Carbon monoxide is:
A highly toxic, odourless gas that is a product of incomplete fuel combustion
Physiological aspects of exposure to carbon monoxide:
- Binding affinity of carbon monoxide for hemoglobin is about 210 times that of oxygen
- Oxygen carrying capacity of the blood is reduced in heavy smokers
- Heavy smokers may become hypoxic at altitudes below 10,000ft ASL
Initial symptom of carbon monoxide poisoning would be
Blurred thinking
Four areas of the body that are most sensitive to mechanical effect of trapped gas are,
GI tract, teeth, sinuses, middle ear
Primary focusing element of the human eye is:
Cornea
Rods are for:
Night vision
Black hole illusions results in flying an approach:
Too low
You see a plane moving next to you when you’re stopped and think you are moving backwards, the illusion is called:
Vection illusion
Rain on the windscreen may cause the runway to appear:
Closer and lower
At night, during the transition phase to a lighted up sloped runway there is the possible illusion of ____________ when there is rain on the windscreen.
Being very high and thus increasing rate of descent
You are flying a low altitude downwind with a strong tailwind. What illusions will be sensed as you enter the base turn?
Aircraft skidding, airspeed decreasing.
Definition of a CFIT accident is an event which:
An airworthy and normally functioning aeroplane is inadvertently flown into the ground, water, or and obstacle with no prior awareness by the crew
Under the threat and error management model a threat may be defined as:
An event or error that occurs beyond the influence of the flight crew.
Useful consciousness at 20,000ft
5-12 mins
When are CFIT accidents most likely to occur?
Below DA/MDA
What effect can happen when the airplane is in a turn and the pilot turns their head in the opposite direction?
Coriolis effect
How to avoid a flock of birds?
Climb as the birds natural tendency is to dive
What are the three components of the threat and error management system?
Threats, errors, undesired state (aircraft)
What are the most hazardous runway illusions?
-narrow runway
-upslope runway
-black hole
-blowing snow
