How many liters are in the primary and auxiliary converters of the passenger oxygen system?

The primary and auxiliary converters of the passenger oxygen system are both designed to accommodate specific capacities to ensure the safety and well-being of passengers in the aircraft. In this case, the correct answer reflects that both the primary and auxiliary converters have a capacity of 75 liters each.

This design allows for a sufficient supply of oxygen to be available for all passengers in case of a decompression event or other emergencies where supplemental oxygen is required. It's important that the system is equipped with ample oxygen resources to support the entire passenger load, particularly during critical phases of flight or in emergencies.

The configuration with both converters having equal capacities ensures that the system is not only redundant but also efficient in delivering oxygen when necessary.
