ATR Oxygen Test
Hi all,
Just wondering if any other ATR drivers out there can answer this one for me. When doing the oxygen test, if the needle on the oxygen pressure gauge on the overhead panel drops back all the way as you press the test button at the mask, what exactly does that mean; even if you get the yellow cross indication at the mask panel and hear the hiss of oxygen as you do the tests ?
From reading some ATR notes available on the web, it says a particular valve is towards the closed position and if you did end up needing to use your oxygen mask in flight, you wouldn't get the right amount or perhaps none at all.
If anyone can clarify on exactly what it means I would be most grateful.
Many thanks,
