Answer 2

Bends»stinging pain,in the joints
Skin»tingling ,prickling and itching of the skin
Chokes»chest pain ,gas bubble in the alveoila
neurological»double vision,impaired vision ,impaired tactile ,muscle weakness

Answer 3

100% oxg
Keep patient warm
Submit patient to hyperbaric treatment ,if necessary
Do not rub affected parts

Answer 4

Radial acceleration(centripetal)&raquo_space;a change of direction without change in speed

Linear accelration»change in speed wihtuout change in direction ,such as in increase in thrust

Angular acceleration»when both speed and direction are changed

Answer 5

Angular acceleration»occurs when both speed and direction are changed ,as in a spin

Answer 6

1g»accumultae in the lower body

2g to 5g»apparent increase in body weight,internal organs and facial area diplaced downwards

8 to 9 g loss of sensory

Answer 7

Do not fly withn 12hours of swimming with compressed air

Avoid flying 24hours if a depth of 30ft has been exceeded

Diving to 30ft exposes body to a pressure drop five times higher than a rapid decompression from 7000ft to 30000ft

Question 8

Cabin pressure change restricted:

Answer 8

To 500ft/min climbing

To 300ft/min descending

Answer 9

~short term accelertion»less than about one second

~long term acceleration»more than one second

Answer 10

If an Instant rapid decompression occurs ,avoid any physical activity during next 24h after the flight

Question 11

G force axis

Answer 11

Gz axis is the vertical
Gy axis is the latertal
Gx is the longitudinal axis
