Question

(Oxygen Limits) If any occupant lacks functioning oxygen equipment, descend to an altitude of ____ or less (terrain or fuel requirements permitting).

Answer 1

If any occupant lacks functioning oxygen equipment, they should descend to an altitude of 10,000 feet or less (terrain or fuel requirements permitting) to ensure they receive enough oxygen and prevent hypoxia.

Step-by-step explanation:

In high altitude environments, where the supply of oxygen is limited, individuals who lack functioning oxygen equipment should descend to an altitude of 10,000 feet (3,000 m) or less, if terrain or fuel requirements allow. This is to ensure that the individual receives an adequate amount of oxygen for proper functioning and to prevent hypoxia, which is the deprivation of oxygen that can result in symptoms such as fatigue, headaches, and confusion.
