It cannot climb without slowing down. It cannot speed up without descending.
These are serious constraints.

Hypoxia is unrelated to age. Vision is affected very rapidly by low oxygen
levels (seconds).

Why would I ever try that?

'Twas a joke, Jim!

You'd need a really big engine, and a good cushion of airspeed anyway. :P

Do you work for Microsoft support?

Everything you have said is totally correct and totally unrelated to
the discussion at hand.

What would you think it would be useful for to the general pilot?

It improves cerebration and CNS function, both of which are very sensitive to
oxygenation. For example, night vision works better with oxygen, even at 5000
feet.

Do you have a reference for that 5000 feet number or is this your
opinion?

Real oxygen in real airplanes costs real money and real weight.

Becoming confused or blind because you're a bit low on oxygen can cost you
your life.

Normal, healthy people do not become confused flying at normal GA
altitudes due to lack of oxygen and you don't become blind at any altitude.

Since in most GA aircraft it is a struggle to get to an altitude
where oxygen is required and except around places like the Rockies
seldom necessary to go that high, most people don't bother with it.

There are altitudes where it is required, and altitudes where it's just a good
idea. The latter are much lower than the former. If you decide you don't
need it, you don't have to use it (unless regulations require it), but I don't
see what harm there is in having it on board.

That's because you have never payed real money to fly nor ever performed
real pre-flight planning.

Once again, no context to understand the answer.

For what?

For keeping your head clear. Five thousand feet is quite a distance up
unless
you actually live at that altitude, and a bit of pure oxygen will not hurt
and
may well help.


Apparently you would find it helpful in flying your desk. Might I suggest
you turn up the flow rate.

Well then, it seems very obvious you need to similate a tune-up. Simulate
cleaning the plugs and see if that helps.

Energy management; once again no context for understanding.

When flying at night. I didn't believe it would make a difference
either until I tried (the most noticeable effect is the improvement
in your vision)

It is my understanding that it is time and age dependant.

Two questions; how old are you and do you see an immediate improvement
or does it depend on how long you are flying.

early 40s, but I heard similar comments from kids in their 30s. :-) The
improvement is noticeable quite rapidly (I'd say within minutes of
getting supplemental oxygen); for instance, the lights on the ground
that looked like seen through a little haze become sharp.

Get yourself through one of these high altitude training thing; you'll
be able to experiment a few other interesting side effects of hypoxia.
