Last fall, Ian Bently mentioned that he thought oxygen systems should be a high priority for Cirrus. After all, Cirri can fly higher than the usual spam cans, and the pilot population isn’t as young as it was. But we’ve been hounding Cirrus for de-ice, diesel, weight increase, etc, with hardly a word for oxygen. I’d put that above de-ice on my personal list.
I was wondering the same thing. For my Bonanza, I currently have an Aerox system with the “Oxysaver” cannulas that has MUCH lower consumption rates than the system described in the Cirrus POH. I cannot understand why the POH system is specified as approved to the apparent exclusion of others.
Since my Aerox system is presumably approved for use in aircraft, what, if anything, keeps me from legally using it? I’d consider installing one of the Aerox “built-in systems” kits ( http://www.aerox.com/BuiltInSystems.html) if possible. What would this entail?
I am still reading the POH for the SR20. It is a legally binding document for the pilot and I was dismayed to find that Cirrus specifies only on brand of portable oxygen system is acceptable for use in the SR20. It further states that if you use it you cannot have a copilot (or anyone else in the right front seat). Will Sony pay them to require only Sony audio equipment be plugged into the music ports on the Garmin 340?
I checked the archives and the oxygen question was raised in December, 2000, but was not answered.
