What should be done with oxygen supplies if equipped with permanent aviox?

When dealing with oxygen supplies in an aircraft equipped with permanent aviox systems, it is essential to understand the operational procedures and safety protocols in place for managing different types of oxygen equipment. The correct approach is to deplete the aviox to empty first. This is primarily because aviox systems, often designed for prolonged use and reliability, may be tasked to handle major emergencies that require a steady supply of oxygen.

Using the aviox system first ensures that you are utilizing the established, continuous flow of oxygen that the system can provide, which is critical in maintaining sufficient oxygen levels during emergencies. These systems are typically integrated into the aircraft and designed to handle specific scenarios effectively, allowing for the other oxygen supplies, such as portable oxygen bottles (POBs), to be saved for instances where mobility is required or aviox cannot be used.

This procedure helps to manage the oxygen supply efficiently and ensures that all available systems are used optimally while reducing the risk of running out of oxygen at a critical moment. It is essential to follow this sequence to ensure passenger and crew safety during situations requiring supplemental oxygen.
