What is the typical flow rate of oxygen in the DEPLOY position?

The typical flow rate of oxygen in the DEPLOY position is characterized as a high constant rate. This setting is crucial in emergency situations, such as cabin depressurization, where a rapid and continuous oxygen supply is necessary to ensure that passengers and crew receive adequate oxygen to maintain consciousness and function.

In the DEPLOY position, the oxygen system is designed to deliver a consistent and substantial flow of oxygen, allowing individuals to breathe easily until the situation stabilizes or alternative measures can be implemented. The significance of having a high constant rate lies in its assurance that oxygen is readily available in potentially life-threatening scenarios, where every second counts and where physiological needs must be prioritized.

The other options reflect different conditions that may not meet the urgent needs for oxygen in an emergency context. The variable rates based on altitude imply a contingent supply that may not be appropriate during a critical event. A low variable rate would be inadequate for maintaining oxygen levels, especially under stress. Standard cabin pressure does not pertain directly to oxygen flow rate in emergency procedures, focusing instead on routine operations within a pressurized environment.
