23
Q

Night vision is affected above?

A

Night vision is affected above 8 000 ft

24
Q

TUC Time of Useful Conscientiousness at

  • 18 000 ft = ?
  • 22 000 ft = ?
  • 25 000 ft = ?
  • 30 000 ft = ?
  • 35 000 ft = ?
  • 43 000 ft = ?
A

Time of useful conscientiousness at

  • 18 000 ft = 30 mn
  • 22 000 ft = 4 to 8 mn
  • 25 000 ft = 2 to 4 mn
  • 30 000 ft = 30 s to 1 mn
  • 35 000 ft = 15 to 30 s
  • 43 000 ft = 8 to 12 s
25
Q

Minimum time between scuba diving and flying?

A

24h

26
Q

Breathing equipment must be used for the pilot above?

A

40 000 ft

27
Q

Actions in case of depression?

A

1/ Vital: get to oxygen

2/ Then emergency descent

28
Q

TUC after a cabin loss of pressure at 35 000 ft?

A

Time of Useful Consciousness is 30 to 40 seconds

29
Q

Characteristics of blood in the pulmonary artery?

A

Poor in oxygen

Rich in carbon dioxide

30
Q

Normal breathe rate for an adult is

A

12 to 20 per mn

31
Q

Law that governs oxygen transfers in the alveoli?

A

Fick’s Law: diffusion from high concentration areas to low concentration areas

32
Q

External / internal respiration are?

A

Metabolic process inside the cells

  • External: swapping carbon dioxide for oxygen
  • Internal: the opposite
33
Q

Severity of hypoxia depends on? (4 elements)

A

1 - Rate of decompression
2 - Physical fitness
3 - Flight level
4 - Individual tolerance

34
Q

Hyperventilation causes blood to become more?

A

Alkaline

because less carbonic dioxide thus less carbonic acid

35
Q

TUC is?

A

Time of Useful Consciousness in an environment with poor oxygen:

  • Time able to perform flying duties
  • Attention, not the time until unconsciousness!
