Bill,

Great questions. = The ultimate answer is this is really a life or death decision. About = once or twice a year some pilot runs out of O2 above 20K' and drills = along until the plane runs out of fuel. 

So- O2 switch = should be in front of you-- not on floor, behind seat etc. 

Mask = definitely. 

Around your = neck.

Preflight system before takeoff to ensure proper flow.. = especially if bottle is remotely mounted. 

Practice-- at night blindfolded = with Tim's mum in law screaming at you. 

You would be surprised how stupid = one can get at FL250 when the cabin depressurizes and how little time = (seconds) it takes. All the stuff you hear about "time of = useful consciousness" applies to a healthy cardio fit 25 year old = lieutenant flying an F/A-18. It does not IMHO apply to a 60 year old out = of shape fat guy in a Lancair!

(remember I am also = the same wimpy guy that said do not practice stalls in a = Lancair so take this with a grain of salt)




For starters, if there was a=20
