At what psi is the T6A Emergency Oxygen Cylinder considered full?

The T6A Emergency Oxygen Cylinder is considered full when it contains oxygen in the range of 1800 to 2200 psi. This pressure range ensures that the emergency oxygen system is adequately supplied for crew use in the event of cabin depressurization or other emergencies requiring supplemental oxygen.

A full cylinder at this pressure ensures that pilots can rely on the system when needed, as it indicates sufficient oxygen for safe operation under high altitude conditions where supplemental oxygen is crucial for maintaining cognitive function and performance. Keeping the cylinder within the specified pressure range is vital for safety and operational readiness.

Other options listed either fall below or above the acceptable limits for a full cylinder, indicating that they do not meet the operational requirements defined for the T6A aircraft’s emergency oxygen system.
