Hi Folks,
The question refers to the settings of the flight crew oxygen masks. While two of the answers are clearly wrong, two seem nearly right to me:
In Emergency mode the mask will supply oxygen at slightly above normal pressure for use above 32,000 ft.
In Normal mode the mask will mix oxygen with cabin air as a diluter demand system.
I went for the first option because it seemed wholey right. The second option was 'spoiled' by being called 'DILUTER' and I didn't think it was labelled that way.
Otherwise what have I got confused?
