What is positive and negative g?
Positive g is when aircraft goes up, blood goes down.
Negative g is when aircraft goes down, blood goes up.
What happens to the heart during increased g loads.
Parts of the body get heavier, therefore the heart has to work harder to pump blood.
What is the first organ in the body to show deterioration?
Eyes
During increased g loads in what order does deterioration occur in the body?
- Loss of colour (grey out)
- Tunnel vision
- Black out (vision is all black)
Further increase in g will lead to G-LOC (G induced loss of consciousness)
In what areas does blood accumulate during negative g force?
In negative g large amounts of blood accumulate under pressure in head, neck and upper areas of body.
What are some symptoms of negative g?
Facial pain
Bursting of blood vessels in the face and eyes
The pushing of the lower eyelid to cause redout (mixing of blood with tears)
The upward rush of blood causes heart to slow down
When can grey out occur?
Only be experienced during sustained load of +3.5g
When does black out and G-LOC occur?
Black out and G-LOC occur at load of +5g
What are some factors increasing G tolerance.
G -suits have gel disabling blood from going up and down
100% 02 breathing
Anti G straining manoeuvre
Regular training
