Q

Vision

Eyes

A

Most important sense for flight
Cornea-primary focusing element of the eye
Pupil-dark center portion where light enters
Iris-color portion, responsible for the dilating and constricting of the pupil
Lens-behind the iris and performs delicate focusing of light on the retina
Retina-membrane lining the back of the eye that contain photoreceptor cells
-photorecptors send impulse to the brain via optic
Cones-responsible for the color vision and higher light intensity
Rods-unable to discerne colors but very sensitive in low light(night)
Fovea-area of retina with high concentration of cones and no rods
-visual detail and sharp central vision

  • air traveling over the upper surface of the airfoil moves faster
  • creates a lower pressure on the upper surface than the lower surface, thus creating lift

Q

Fog Formation

A

Formation:

  • advection: warm air flows over cold surface, water or land, coastal fog wind
  • upslope: moist stable air being cooled as it moves upslope
  • precipitation: warm rain/drizzle falls through cool air
  • ice: temp below freezing, moisture freezes directly into ice crystals
  • steam: cold dry air passes over warm water

dew point: temp at which air must be cooled to reach saturation

  • Extends over longer periods of time and often has psychological roots
  • Caused by continuous high stress levels
Forms in:
weakness
tiredness
palpitations of heart
breathlessness
headaches or irritability
  • not relieved by proper diet and adequate rest and sleep
  • often requires treatment by psychologist
42
Q

Middle Ear Block

A
  • trapped gas(air) expansion accounts for ear pain and sinus pain, as well as a temporary reduction in hearing
  • Eustachian tube normally closed, but opens when chewing, yawning, or swallowing
  • may not be able to equalize pressure on the ears if pilot has a cold, ear infection, or sore throat
  • during a climb, middle ear air pressure may exceed the pressure of the air on the external ear canal, causing the eardrum to bulge outward
  • during descent, opposite happens, eardrum will bulge inward
43
Q

Considerations For Night Flight

A
  • keep eyes adapted to darkness
  • avoid bright lights before and during flight
  • allow eyes to adapt to darkness for 30min prior to flight
  • use dim white light or red/green light to preserve night vision
  • adjust cockpit lights to minimal brightness
  • consume a healthy diet(vitamin A and C)
  • maintain general physical health
  • avoid CO, smoking, drugs, alcohol, hypoxic conditions
44
Q

Night Blind Spot

A
  • located in the center field of vision
  • caused by the concentration of cones at fovea
  • reducing visual performance at night in the center of field of vision
  • at night the rods must be exposed to the object for clarity
  • this can be done by looking 5°-10° off center exposing the rods to the image(off center viewing)
45
Q

Landing Ilusions

A

Featureless terrain:
cause by an absence in ground features(water, darkened areas, snow) creating an illusion of higher than actual altitude causing a lower than normal approach

Atmospheric:
rain on the windscreen, haze, or g=fog can create an illusion of being further and higher from the LZ causing a lower than normal approach

Ground light:
lights along a straight path(roads, trains, shoreline) can be mistaken for runways. Bright lights can create the illusion of being too low

46
Q

False Horizon

A
  • occurs when the natural horizon is obscured or not apparent
  • can be generated by confusing bright stars or city/street lights
47
Q

Autokinesis

A
  • condition caused by staring at a single point of light against a dark background for more than a few seconds
  • after a few moments, the light appears to move on its own
  • can be prevented by focusing on objects at varying distance and conducting a normal scan pattern
48
Q

condition in which eye has a greater difficulty seeing in low-illumination areas, even though daytime vision is normal

http://www.skyandtelescope.com/wp-content/uploads/NightMyopia.jpg

49
Q

Empty Field Myopia

A
  • condition that usually occurs when flying above the clouds or in haze providing nothing specific to focus on
  • eyes tend to relax and seek a comfortable focal distance(10-30ft)
50
Q

Blind Spot

A
  • area where the optic nerve enters the eyeball, has no rods or cones
  • leaves a blind spot in the field of vision which is normally compensated for by the other eye
51
Q

Alcohol

A
  • acts a central nervous system depressant
  • quickly absorbed into the body through digestive tract
  • takes about 3 hours to rid the body of the alcohol in one drink
  • hungover is still considered being under the influence of alcohol and greatly affects the ability to fly
  • FAR Part91 declares an 8hr bottle to throttle or a 0.04%>
  • 10z of alcohol can equate to an additional 2000ft of physiological altitude
  • impaired judgement -reduced reasoning power
  • decreased sense of resp -lower attention span
  • affects coordination -decrease speed/strength
  • constrict visual field -lessen the efficiency of eyes
  • diminish memory -increase frequency of errors
  • increase vision/hearing impairment
52
Q

Sinus Block

A
  • similar to middle ear, sinuses equalize pressure through small openings that connect sinuses to nasal passages
  • congestion from an upper respiratory infection such as a cold can block an opening and slow equalization
  • can cause pain in the sinus areas above each eyebrow , in each upper cheek, or even upper teeth to ache
  • can be avoided by not flying with upper respiratory infection
53
Q

Spatial Disorientation

A
  • state of temporary confusion resulting from the misleading information being sent to the brain by various sensory organs
  • incorrect mental image of what is actually happening
  • lack of orientation with regards to the position, attitude, and movement of the aircraft in space
  • collectively the three integrated systems provide the info required to understand its physical orientation
54
Q

Spacial Disorientation

Three Integrated Systems

A

Visual system:

  • sight is the element of position based on what is seen
  • primary sense that confirms the systems signals
  • without the visual system the vestibular system becomes unreliable

Vestibular system:

  • portion of the inner ear which provides info about balance and rotational moments
  • signals from this system are sent to the brain to interpret motion

Somatosensory System:

  • nerves in the skin, muscle/joints along with the hearing sense, position based on gravity, feeling and sound
  • feeling light in the seat in low-g conditions
55
Q

Supplemental Oxygen Requirements

A

FAR 91.211
-use of oxygen at altitude is necessary because of the potential for loss of consciousness
-certain flights predetermined for which oxygen is
required

Flights between 12,5000 MSL and 14,000 MSL for more than 30 min
-minimum fight crew members must be equipped

Flights above 14,000 MSL
-minimum flight crew members must use supplemental oxygen at all times

Flights above 15,000 MSL
-all occupants must be provided supplemental oxygen

  • low blood volume, blood disease(anemia), unable to hold oxygen

Stagnant:

  • oxygen rich blood is not flowing to the body
  • body unable to overpower g forces, arm falls asleep due to decreased blood flow, decreased output from the heart, cold temps

Histoxic:

  • bodies tissues or cells unable to use oxygen
  • effects of alcohol/drugs
58
Q

59
Q

Carbon Monoxide Poisoning

A

(CO) is a colorless and odorless gas produced by interal combustion engines

Signs/Symptoms:
headache
blurred vision
loss of muscle power
dizziness
drowsiness
Corrective actions:
turn off heater or defroster

emergency situation

Controls:
mentally prepare for flight
try and relax and think rationally

62
Q

Pilot Stress

A

Stress = bodies response to demands placed on it

  • normal response to life situations
  • can be positive for performance depending on level
  • good cockpit stress management starts with good life stress management
