Bill,

I respectfully disagree. With two such incidents under my belt (n=3D2) a= t FL210 and FL 280 my time before stupid consciousness was on the order of 5= -10 seconds. Results may vary but you can take training in an altitude chamb= er and see how you would fare. I agree you need a good hard mask with a buil= t in mic. Mountain High sells such a mask. I know others on this list have h= ad rapid decomps at flight levels and may have different experiences. Ralf h= ad one in his IVP last year.

Best regards,

For a= good rule of thumb, think 2-3 minutes time of useful consciousness at FL 23= 0

In my IV-P, I use a small double bailout bottle s= ystem (from an ejection seat)  located on the fwd side of the wing carr= ylthru.  where activation is available to either pilot.
Each pilot has a mask available in a little side pocket.  Turn the= little knob and each pilot has 10 minutes of O/2.. Cant get much simpler th= an that.

When I first flew my plane before it was p= ressurized, I used a quick-don O-2 mask (with mic) surplus from a 747 at a f= lowrate of 3 lt/min.  Worked fine at 20K

Hope this helps a little

BTW, I lost pressurization at 17K after electrica= l failure on the way to the LOBO meeting In Sedona last year.  Didnt ev= en bother to turn on the O/2.  Think
it might have had something to do with my increased breathing rate..
