MIXTURE you have a point, perhaps PPRUNE should only allow professional pilots, engineers, air traffic controllers, and human factors specialists on here, I fall into two of these groups.
In previous post, oddly a captain from EXC (fireflybob) who I flew with many years ago with gave a very cogent explanation on the oxygen systems, for those who are pilots and PAX.
And various other pilots, have put forward good practice as to the pre flight procedures in relation checking equipment in relation to decompression and briefing to all occupants of the flight deck.
I say this, as a jump seat occupant, from my days with EXC, i was always encouraged to to check my mask and supply. About 14 airlines later on a flight from Accra to Lagos via Benin, DC9, I checked my emergency supply, preflight, and the pipe had completely perished, so I say thanks to fireflybob as he stressed the importance of checking emergency oxygen as SNY before flight.
