The magic words: "declaring an emergency". On the other hand, even at 3000-4000 feet per minute, it can take a while to get from 35,000 to 10,000 ft.

- hanniabu 6y agoI would think more than 10k would be sufficient considering the Everest base camp is around 18k feet, but of course the lower the better.
- jcrawfordor 6y agoThe point where hypoxia can set in varies from person to person, esp. when accounting for people with respiratory disorders. 10,000 feet is often considered a rough line where the altitude is no longer safe for everyone (that is, particularly susceptible people may begin to show symptoms), but the FAA progressively requires pressurization or supplemental oxygen from 12,500 to 15,000 feet. Altitude sickness (different from hypoxia but sometimes also quite severe) will occur below 10k in some people if there has been a rapid change in altitude, but fortunately it is much more survivable than hypoxia.
