200
What three systems help the body fight spatial disorientation?
Visual system,
Vestibular system: inner ear,
Somatosensory system: body sensors
200
What is motion sickness caused by?
A product of the brain receiving conflicting messages about the body’s true position
200
How does a pilot deal with decompression
Descent and/or oxygen
200
How does an altitude chamber help pilots train?
Helps a pilot get familiar with the warning signs of hypoxia
300
What happens to air pressure and air molecules as the altitude increases?
Decreasing pressure making it harder to breathe
Air molecules Decreases as altitude increases
300
What is the respiratory system’s main purpose?
Main purpose is to take in oxygen and get rid of carbon dioxide
300
What are motion sickness symptoms?
nausea, dizziness, paleness, sweating, and vomiting
300
Who wears full pressure suits
Astronauts and pilots
300
What do military and civilian pilots use flight simulators for?
Imitates real-life situations and dangers that pilots may face
Pilots can make mistakes,
Cheaper than flying…wear and tear, fuel
400
How does Henry’s law impact fliers?
gases in the blood and tissues can try to escape in the form of bubbles
400
What are the cardiovascular system’s principal function?
Use blood to carry oxygen from lungs to organs or body tissue
Uses blood to move carbon dioxide from the tissues to the lungs
400
What is g-force and the three types?
G-force is a measure of gravity’s accelerative force
Gx: from the chest to the back
Gy: from shoulder to shoulder
Gz: from head to foot
400
What three methods are used to deliver oxygen

Diluter demand,
Pressure demand
400
What is a Barany chair and how does it help pilots?
Spinning device that demonstrates the hazards of spatial disorientation
500
What is hypoxia and two impacts on the body?
Hypoxia—a state of too little oxygen in the body
Impacts the brain first…….judgement goes
Causes tunnel vision
500
Why are pilots concerned about what substances they put into their body?
Smoking, Alcohol, Diuretics and drugs can cause the body numerous problems which impact negatively on their ability to fly the airplane
500
Which is the most hazardous g-force? What can it do to the pilot?
More dangerous is the foot-to-head -Gz;
Pilot may experience red out; the next phase is loss of consciousness
500
What was the problem with partial pressure suits and how were full pressure suits better?
Partial-No way to release heat and sweat, and were too heavy Restricted movement & didn’t adequately protect the body
Full—Built-in ventilation system

What would happen if a pilot tried to escape a damaged fighter with only a parachute?
If a fighter pilot tries to escape a damaged fighter with only a parachute, he or she would be battling g-forces and windblast
Windblast can injure or even kill a pilot
G-forces can pin a pilot in place
When clear auto unlatch
