So it would be fair to say:
1. That some airlines change the oxy bottles when the pressure is low...for safety reasons?
2. And other airlines recharge the oxy bottles from a central remote charge point for economic reasons?
But doesn't QANTAS put safety and security first? Help me here. I am confused.
We at BA also charge our Oxy in-situ.
Some might say there is more risk involved in disturbing the systems and changing bottles than there is in charging from a remote point - horses for courses
