Hi Alex and Co,

With regards to the aforementioned Volume 6...

I've only had a few minutes to read some of the data but I must join the chorus of "its very complete and impressive stuff" however a couple of things stuck out, perhaps I missed something but just in case....

The Purpose and Scope gives the impression (to me) that this is the analysis of your proposal (Deeplife Ltd Open Revolution Submission) and even goes as far as saying that all references refer to that submission.

(There is also a couple of typos but my spelling is terrible and I can't load the Rebreather World spellchecker at work so won't point my finger there! )

Later on in the document there are numerous references to a specific existing rebreather by way of failure type (battery bounce) components used (O2 and Dil manual injectors) etc that are clearly not part of the Open Revolution Submission, I do not understand where they fit in the analysis?

The next thing I spotted is that moany of the items are contradictary. For example- O2 Solenoid Stuck closed, the recovery suggested in flying PPO2 manually via manual injection (which of course is somewhat unit specific and doesn't afflict all rebreathers anyway)
On the very next page it is suggested that the manual injector is a failure point that should be eliminated!!


Perhaps I have missunderstood the purpose of this document, its seems to me a list of failures possible on the APD Inspiration, not an analysis of the Open Revolution submission (in which I imagine these issues are resolved)
