I have recently been putting together a DIR compliant rig and a question came up, while I was bringing in my 1st and second stages for servicing, and frankly, I thought it was a good enough question that seems to escape a quick answer. In the event of a first stage failure on the right post, or any sort of failure that requires turning off the right valve ( or isolator ), which is where the wing inflator hose lives, am I not correct that the only option is to disconnect the dry suit inflator hose and attach to the wing inflator, leaving you without a quick secondary inflation device? I don't recall any mention in the materials I've read so far ( but have not taken DIR F yet ). The idea of an inflator hose failure ( or no air to the inflator hose ) didn't occur to me as a potential issue, but now that I consider it and have to think it through, with copious amounts of time to consider it, I'm a little unsure how quickly I would have thought of that in a real emergency, with little time to get it wrong. Is this just common sense, or is there a drill I haven't read yet?
