17. Cabin Pressurization Systems
Cabin pressurization is the active pumping of compressed air into an aircraft cabin when flying at altitude to maintain a safe and comfortable environment for crew and passengers in the low outside atmospheric pressure.
Pressurization is essential over 3,000 metres (9,800 ft) to prevent crew and passengers from becoming unconscious through the lack of oxygen (hypoxia) in the thin air above that altitude.

18. Oxygen Requirements
If pressurization is lost above 14,000’, an immediate descent will be made to a cabin pressure altitude of 10,000’ or below.

19. Hypoxia
Lack of oxygen, especially resulting from an inability of body tissue to absorb oxygen under decreasing partial pressure at high altitudes.
Can cause personality changes, impairment of basic senses, dizziness, unconsciousness and death will follow if oxygen lack continues.

20. Hypoxia Effects Time of Oxygen 1 Minute 2 Minutes 3 Minutes 4 Minutes
