Answer 22

Hypoxia starts above 10 000 ft

Question 23

Night vision is affected above?

Answer 23

Night vision is affected above 8 000 ft

Question 24

TUC Time of Useful Conscientiousness at - 18 000 ft = ? - 22 000 ft = ? - 25 000 ft = ? - 30 000 ft = ? - 35 000 ft = ? - 43 000 ft = ?

Answer 24

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
