Final answer:
The maximum time a person can fly above 10,000 ft without supplemental oxygen depends on various factors such as individual health and fitness level. It is advised to use supplemental oxygen above 10,000 ft for extended periods to avoid altitude sickness and hypoxia.
Step-by-step explanation:
In high altitude conditions, the oxygen concentration decreases, making it harder for humans to breathe. As a result, mountain climbers often carry supplemental oxygen when climbing at very high altitudes.
The maximum time a person can fly above 10,000 ft without supplemental oxygen depends on various factors such as individual health and fitness level. Generally, it is advised to use supplemental oxygen above 10,000 ft for extended periods to avoid altitude sickness and hypoxia.
It is important to consult medical professionals and follow appropriate safety guidelines when engaging in high altitude activities to minimize health risks.
