I'm not sure if you are a pilot or what type of experience you have, but everything that she said relating to the systems of an aircraft were very incorrect. She suggests that we have a control that varies the amount of 02 based on how much air is recirculated. I have not flown or even heard of an aircraft that has such a thing. (I am an A&P as well as a pilot.) I guess that it is possible that the latest Boeing or Airbus aircraft have something like this, but even so, that would be a tiny fraction of the number of aircraft flying. Packs are either on or off for the most part. Even temperature control is merely determining how much hot bleed air is mixed together with discharge air from the pack - period. She also suggests that we fly around regularly with some of our packs off - another suggestion that I have never heard of in normal operation. Have one deferred, maybe. The dumbest comment has to be about suggesting that we have better air in the cockpit. We might have a separate temperature control for the pack that gives more than half of it's output in the cockpit (my current aircraft) but the air quality is exactly the same at the vents. Once it is inside the pressure vessle, I don't see how it doesn't all mix together. The only sliver of truth to any of this would be that the "air quality" would be worse towards the back of the A/C... When I flew the EMB-120, the lav was right behind my seat. If someone went in and "dropped the kids off at the pool" we would climb the cabin to get rid of the stink. Too bad for the guy in the back row who got all of the stink on it's way out the outflow valve, (think of standing on a roof smelling a bathroom exhaust fan) but at least they had to stare everyone in the face who knew they just took a dump.
As for some of her other suggestions:
Most airplanes have only a few 02 bottles, for REAL medical emergencies. They are not for Germophobes that get their information from un-informed idiots scaring them to action.
How stupid would everyone look with wet washcloth over their mouth?
Most people who complain about the "dirty air" in an airplane fail to realize that it is probably much fresher than in almost any area with many people in close quarters. The airplane is always leaking, the only way to keep it pressurized is to add more air than is leaking out and to control the rate of the leak. If they really want to go after some dirty air, I would look at your average bus, train, subway, etc... that doesn't have at LEAST two 3" pipes with 60+ PSI of air flowing the entire time.
So to answer your question, that's why we think that she is an idiot.
I have one for you, Amish guy... How do you please an Amish woman??
