Flintstone,
If the mask is dangling in front of you - it is because you have missed ALL the clues and to allow you to see the way ahead, you should don the mask....
It is called fail safe.
I also managed it in the sim on many occasions but the only time I was in an actual fume event - I forgot. Yes, I felt a complete numbskull afterwards; in more ways than one...
One is only trying to help and ask inconvenient questions for the poor xxxxers who are still flying.
