Human Factors Flashcards

1
Q

Hypoxia

A

Lack of Oxygen
Symptoms: headache, drowsy, blue fingernails/lips, sense well being
Cause: insufficient oxygen in blood, low pressure at altitude
Remedy: use of supplemental oxygen, descend to lower altitude, land as soon as practicable

Q

Hyperventilation

A

Symptoms: increased breathing rate, dizziness, tingling fingers/toes, visual impairment
Cause: abnormal loss of carbon dioxide in blood, from rapid breathing, can be a reaction to stress
Remedy: return breathing to normal, breathe into a plastic bag, talk out loud

Q

Spatial Disorientation

A

Cause: no visual references. Illusions caused by motion (centrifugal force, gravity, small velocity changes)
Symptoms: Brain can’t determine orientation based on normal senses. Vertigo
Remedy: training, rely on instruments

Q

Carbon Monoxcide Poisoning

A

Cause: Odorless gas. Smelling exhaust gas is a good sign.
Symptoms: headache, drowsiness, dizziness, tightness in forehead
Can significantly reduce the ability of the blood to carry oxygen
Effects of Hypemic Hypoxia can occur
Remedy: Open windows, turn off heater

Q

Alcohol Effects

A

As little as 1oz liquor, 1 bottle of beer, 4oz of wine can impair flying skills. Alcohol also renders a pilot more susceptible to disorientation and hypoxia.

17
Q

IMSAFE

A 
Illness: 
Medication
Stress
Alcohol
Fatigue
Emotion
18
Q

PAVE

A

Pilot
Aircraft
EnVironment
External Factors

19
Q

Positive Aircraft Control

A

I’m controlling the aircraft, the aircraft isn’t controlling me.

20
Q

Hypoxic Hypoxia

A

Not enough oxygen in your surroundings. Decrease in the number of oxygen molecules at lower pressure altitudes can lead to hypoxic Hypoxia.

21
Q

Hypemic Hypoxia

A

Think “anemia” or blood issues, blood cannot transport a sufficient amount of oxygen to the cells in the body. “Not enough blood”

22
Q

Stagnant Hypoxia

A

“Not flowing” A blood circulation issue to the tissues. Leg falling asleep. Can be from G-Forces.

23
Q

Histotoxic Hypoxia

A

The organ/tissue/cells themselves cannot use the oxygen efficiently. Could be Alcohol related.

24
Q

Middle ear and sinus problems

A

Vestibular system, organs found in the inner ear that sense position by the way we are balanced

25
Q

Hypothermia

A

When body temp is below 95°F. When body temperature dissipates heat more than it absorbs

26
Q

Decompression Sickness

A

Excess nitrogen in the bloodstream after a Scuba.

  • Flying to 8,000ft MSL at least 12hrs after scub
  • 24hrs above 8,000ft MSL
27
Q

Optics: Rods

A
  • More sensitive at night to motion
  • Detect motion
  • Low light conditions
  • Peripheral vision, pilots use off center viewing at night
28
Q

Optics: Cones

A
  • Used for color and acute vision
  • Color vision
  • High light conditions
  • 10° sector scan during the day using central/foveal vision
29
Q

DECIDE Model

A 
Detect (the problem)
Estimate (the need to react)
Choose (course of action)
Identify (solutions)
Do (the necessary actions)
Evaluate (the effect of the action)
30
Q

3P Model FAA Safety

A

Perceive
Process
Perform

31
Q

ICEFLAGS (Spatial Disorientation)

A 
Inversion Illusion 
Coriolis Illusion
Elevator
False Horizon
Leans
Autokinesis
Graveyard Spin/Spiral
Somatogyral
