Task H Flashcards
What kinds of hypoxia are there?
HHHS
H - Hypoxic
- caused by being @ high altitude. (Air less dense, inability of cells to use oxygen carried in blood)
H - Histotoxic
- inability of blood to use oxygen properly
H - Hypemic
- occurs when blood can’t get oxygen to cells (carbon dioxide poising)
S - Stagnant
- when blood isn’t flowing. Caused by either G force or cold. High altitude & cold can compound hypoxia
What are symptoms of hypoxia?
- Confusion
- Impaired vision
- Impaired judgment
- Headache
- Dizziness
- Lack of reaction to stimuli
- Increased response time
- Cyanosis (fingers and lips turning blue or are blue)
What causes hyperventilation?
Breathing in and out to fast and shallow. This can lead to you passing out.
How can you prevent hyperventilating?
- Talking aloud
- Breathing into a bag
- Slowing breathing rate
- Looking outside
What systems in the body can cause spatial disorientation?
- Vestibular
- inner ear
- Somatosensory
- nerves in skin, muscles, feeling, sound
- Visual
- eyes, sense position based on what is seen
What is motion sickness?
It is when the brain is receiving conflicting messages about the state of the body
How can you get carbon monoxide poising in flight and why is it dangerous?
Carbon monoxide poisoning can be caused by using the cabin heat.
It is so dangerous because it is colorless, odorless, tasteless and cannot be detected other than the sticker in the plane.
What are the two kinds of stress?
- Acute
- immediate, perceived as a threat (ex: check ride)
- Chronic
- long term stresses. (ex: money, relationships)
- presents an intolerable burden, exceeds the ability for one person to cope and causes individual performance to fall sharply
What are the two kinds of fatigue?
- Acute
- day to day fatigue (woke up early worked a long day, busy day with a lot of physical exertion)
- Chronic
- continuous high stress situations
Why is it important to drink enough water and eat properly before flying?
- if you do not eat enough it can negatively impact your flight abilities
- not hydrating enough can negatively impact your flight abilities
What can cause optical illusions?
- runway width or slope
- featureless terrain
- ground lighting
What are the rules regarding drugs and alcohol?
- Alcohol
- 8 hours bottle to throttle
- cannot fly with a BAC more than .04%
- Drugs
- none that can effect you contrarily to safety
3 steps to Aeronautical Decision Making
3 P’s
P - Perceive
- perceive given set of circumstances for flight
P - Process
- evaluating the impact on flight safety
P - Perform
- implementing best course of action
Invulnerability
“This won’t happen to me”
What is the antidote for this thought?
This could happen to me
Impulsivity
“Do it quickly”
What is the antidote for this?
Not so fast, think first
