Question

A passenger oxygen briefing must be completed prior to passing what altitude in a pressurized aircraft?

Answer 1

A passenger oxygen briefing must be completed prior to passing 10,000 feet in a pressurized aircraft.

Step-by-step explanation:

According to aviation regulations, a passenger oxygen briefing must be completed prior to passing 10,000 feet in a pressurized aircraft. This is because at altitudes above 10,000 feet, the cabin pressure decreases and the oxygen level in the air decreases as well, which can lead to hypoxia or oxygen deprivation. Therefore, it is important for passengers to be aware of the location and use of oxygen masks in case of an emergency.
