A CRJ700 where my son's girlfriend was a FA recently suffered a pressurization failure. In discussing the incident with Matt I learned a few things that surprise me.
Flying as a passenger I hear the preflight announcement about how the masks will pop out, and how to use them. It all sounds very straightforward. But what they don't tell you is that only ten percent of the passengers must get Oxygen. Do only one in ten masks pop out, or are nine masks devoid of Oxygen? Requirements vary somewhat depending on cruise altitude, and how quickly you can get to 14,000 ft, but it leaves me with concern. Matt says that the situation is not really considered serious because, although some passengers my pass out they probably won't die. How nice!!
In the incident I mentioned above, the first indication the FAs had was that passengers began to pass out. My son's FA friend was also affected, and fell down (fortunately without injury). Eventually the masks popped out. Matt tells me that the masks deploy if cabin altitude goes above 15,000 ft. It seems to me that they should deploy sooner so that no one passes out. By the way, the Oxygen generators produce a smell like smoke, which doesn't calm the nerves of the passengers.
Check out FAR 121 Section 333. Perhaps GM can further enlighten us.
