How do pilots and cope with changes in oxygen???

Question

?

Answer 1

they have breathing apparatus for situations where the oxygen concentration gets too low.

This is mostly for when they are flying at high altitude and I think the big passenger planes are pressurised so that the oxygen levels stay the same.

Answer 2

People suffer from lack of oxygen at higher altitudes because the air pressure decreases as the altitude increases, which causes the lungs to transfer less oxygen to the bloodstream. There are two ways to remedy this problem.

1) Pressurize the cabin, which increases the cabin air pressure.

2) Breathe pure oxygen.

Answer 3

Any aircraft required to habitually fly above 10000ft has to have its cabin pressurised. That's all there is to it.

Aircraft without pressureised cabins can fly above 10000ft if they have oxygen cylinders on board. However, you may not carry passengers above this height unless the cabin is pressurised

Answer 4

they have pressure suits hich re filled with air pockets
