RE: cycles/abx/O2/altitude

Sure I can. Most airlines use only 1 pac, as it saves on fuel. As a matter of

fact, we,PanAm had the first 747SP's that would fly up to 15 hours at a time.

WE flew non stop JFK-NRT( Japan) we were in the air for over 12 hrs. At that

time we actually flew through the ozone layer, over the North pole, and down

to Japan. Our cruising altitude was 45,000. It was learned that ozone filters

needed to be fitted, but this took place in the early 80's.

Today, most major airlines fly at about 35000. The air pressure should be

around = to 8000 in the cabin. There are portable O2 bottles on all

commercial aircraft.

One way around a lot of the pressure problems is check with the smaller the

smaller regional airlines. Hope this helps. Mike

Mike,

Do you know what altitude the cabin is usually pressurized at?

Maybe this is another example of CFIDS being like altitude

sickness/lack of O2 to the brain?

Maybe you can say if this is true also, I heard that there

are several " air packs " on planes (I don't know what an

air pack is, I just read about it). I heard that in order

for there to be good air flow through the cabin, all should

be open, but in order to save on fuel, some of the air packs

are turned off (wouldn't that reduce O2 level a bit?).

Do you know if this is true?

Once I was on a flight from Seoul to US. The plane was SO

STUFFY I was starting to have trouble breathing. I asked

the flight attendant if there was something she could do.

A few minutes later there was this whoooshing sound and

fresh air flowed into the plane. Night and day difference!

I was wondering if that was an example of a plane running

with an air pack or two off and opening it when a passenger

complained. Can you shed any light on this?
