Oxygen Systems (was O2 Flows w/Switch Off)

[Mark Hislop]

Bob:

You mentioned that the P model can go higher. I know that physically it can go higher. However, I was under the assumption that legally I can't go higher, even with oxygen, because it would violate the certification. Or do I have the option of dumping the prssurization and using the manufacturer's O2 system (tanks, not generators)?
