| Re: Offboard connection setup - Thoughts please?
Womble,
Curious as to why you specifically want to:
"1) use a redundant o2 source
2) isolate the solenoid
3) allow access to onboard and offboard diluents through the ADV
4) allow access to onboard and offboard gasses throught the BOV"
What is your failure analysis for needing redundant O2 physically bolted to the rig, wouldn't an O2 stage suffice with whip for manual inflator?
Could you add a standard 2nd stage shutoff close to your 1st stage for the solenoid feed lp hose, allowing open/close solenoid option, without disconnecting any hoses. Similar to what I understand the boris has for dil/o2 cutoff.
Do you need the ADV to have dual feed, wouldn't it be less complex to just alternate to manual inflation if the ADV or its feed fail?
Use of a gas switch block allows access to on/off-board gas, but how do you confirm what gas you are breathing under stress? In particular I am thinking of when a hypoxic dil is in the onboard gas you have to go emergency oc through the bov on the surface and lights out... or alternatively, you accidentally leave the gas block switched to a hot mix from a stage through decent, need a couple of sanity breaths due to high workload on the bottom and ox-tox....
Just my 2 cents
