What is the primary function of oxygen systems in an aircraft?

• A. To cool the cabin temperature
• B. To supply supplemental oxygen during cabin depressurization
• C. To inflate life vests
• D. To regulate cabin pressure

Answer: (B)

The primary function of oxygen systems in an aircraft is to supply supplemental oxygen during cabin depressurization. In the event of a sudden loss of pressure in the cabin, the oxygen system is designed to provide passengers and crew with the necessary oxygen to breathe comfortably until the aircraft can descend to a lower altitude where the atmospheric pressure is sufficient for normal breathing. This is particularly crucial because, at high altitudes, the lower air pressure can lead to hypoxia, a condition where the body does not receive enough oxygen. The oxygen system is typically equipped with masks that automatically deploy in a depressurization event, ensuring that individuals can quickly access supplemental oxygen. Understanding this function is vital for the safety and well-being of everyone on board, as it directly addresses the physiological needs during a critical situation.
