Hi,I came up with the follwing idea. I'd like an oxygen gauge in my cockpit that starts to empty a tank at lets say 10000ft. So you would have to consider the flow and finally would be forced to go lower on long flights e.g..Has someone stumbled accross something like that in any panel, freware or payware? I remember I had an oxygene gauge in one of FSD's panels, but as far as I can remember it did nothing.Unfortunately I have no idea of programming and coding, so if someone could lead me into a direction where something is avilable I would be most grateful.Alex
