What's minimum safe O2 level?

The real question was:
Why would you want to fly for 3.5 hours at the edge of a condition which the
FARs state is only safe for 30 minutes or less?

Why would you automatically assume that because something is LEGAL that
it is also automatically safe?

I didn't say it was safe. I said that the FARs said it was safe.

That was a slight mis-type in that actually I meant that the FARs *implied*
it was safe.

Therefore they imply that above 12,500 for more than 30 mins without oxygen
is unsafe. Certain things I accept as the cumulative knowledge of those who
went before me :-)

The FARs don't say what is safe. The say what is legal.

(Well... there was a little more to that quote than that...I think the next
part said that I meant that the FARs *implied* it was safe. But no
matter....)

What you say is absolutely true and I agree with you.

But I also agree that the FARs say it is legal (for the most part) because
those that have gone before us have shown it to be safe, or at the very
least, the least risky.
