What is the purpose of the maximum concentration light in oxygen systems?

The purpose of the maximum concentration light in oxygen systems is to show the maximum oxygen concentration available. This indicator is crucial in managing the oxygen supply during flight, particularly at high altitudes where the atmospheric pressure is low and the need for supplemental oxygen increases. By signaling the maximum concentration available, the light helps ensure that pilots and crew are aware of the capability of their oxygen system to provide adequate oxygen levels for safe operation, especially during critical phases of flight where hypoxia could occur.

Knowing this maximum concentration allows users to make informed decisions regarding their oxygen use. Understanding how much oxygen they can access is vital for maintaining performance and safety in low-pressure environments. This focus on maximum concentration also helps in planning for duration and management of the available oxygen supply throughout the flight.
