Now I know what it says in the CAR'S and in the A.I.P about 30 min above 10K and all, but what is the highest you've been without oxygen and for how long?
Just seeing what everyone thinks of this particular area of flight, weather they go above 10 thou or not....
Oxygen....

I used to all the time on long trips in the Ho. I fly medevac now and one time had to fly home unpressurized. I was at 10K and went back to check my O2 sats on the heart monitor. I came in at 88%. Medics generally give O2 once sats go to 93%. Needless to say, I went forward and put my mask on.

"Use of Oxygen
605.32 (1) Where an aircraft is operated at cabin-pressure-altitudes above 10,000 feet ASL but not exceeding 13,000 feet ASL, each crew member shall wear an oxygen mask and use supplemental oxygen for any part of the flight at those altitudes that is more than 30 minutes in duration.
(2) Where an aircraft is operated at cabin-pressure-altitudes above 13,000 feet ASL, each person on board the aircraft shall wear an oxygen mask and use supplemental oxygen for the duration of the flight at those altitudes.
(3) The pilot at the flight controls of an aircraft shall use an oxygen mask if
(a) the aircraft is not equipped with quick-donning oxygen masks and is operated at or above flight level 250; or
(b) the aircraft is equipped with quick-donning oxygen masks and is operated above flight level 410."

Been to FL240 and took the O2 mask off. Ok for about 6 minutes. It was in the CAF high altitude chamber in Edmonton. They had you do a simple task like addition, or draw a stick house on paper. Start with mask on then take mask off. 5 or 6 minutes later the drawings look like a small preschooler drew it. The instructor then made me put the mask back on. Recovery took only seconds. Spent 4 days @ 9700 ft. @ the ski hill @ Taos N.M. with no ill effects. Most people are good for 10,000 above the altitude of acclimatation so Calgarians can do better @ 13,00 than Vancouverites. If anyone has the chance to take the high altitude indoc offered by various organizations, it is well woth the expense and effort.
The average pilot, despite the somewhat swaggering exterior, is very much capable of such feelings as love, affection, intimacy and caring.
These feelings just don't involve anyone else.

The rules governing the use of oxygen are common sense guidelines put in place for flight safety.
Why gamble with so many variable factors that could degrade your ability to think clearly while flying? Assuming of course that you are capable of thinking clearly even with sufficient oxygen which some here seem to be incapable of anyhow. :mrgreen

The hardest thing about flying is knowing when to say no
After over a half a century of flying no one ever died because of my decision not to fly.

It wasn't at Sault College, but I was hung over like a bastard, had a few smokes immediately before flying and went up to 6500 to do some spins with an instructor.
We went into the spin, and the instructor said, "recover", but I was having such a great time spinning around, that I didn't feel like it. So I went around, and around, then he recovered.
Afterwards, he asked me why I didn't recover. I didn't know why until I took some Human Factors courses at the College here.
What happened, I think, was hystoxic hypoxia- hypoxia caused by chemicals (leftover booze, and carbon monoxide) in the blood stream.
Needless to say, I don't fly hung over anymore. Hypoxia is real, and it makes you do stupid stuff, or not do the right thing when you should.
Words to the wise.
