Preparing for a XC : Bathroom Breaks

Dehydration gives no warning and can seriously degrade your pilot skills
just when you need them most.

Dehydration most certainly does give a warning: thirst. If you get
thirsty, drink. If you're not thirsty, you're not dehydrated. You
won't dehydrate enough in three hours to have any effect on your
flying ability unless it is extraordinarily hot inside the aircraft.
Make sure you are hydrated before the flight and you'll be fine.

On the other hand, having a desperate urge to pee and no place to do it can
also degrade your performance.

Much more so than the subclinical dehydration that might occur on a
short flight of three hours.

Well, you may get thirsty before dehydrating while playing with your joy
stick, but people who work and play in hot climates know that that is
not true. Physiologists know that dehydration can precede thirst. The
military knows it in training troops. Pro sports teams know it. Serious
hikers know it. All plan appropriate water consumption based on planned
fluid losses, not thirst. You also imply in another post in this thread
that the kidneys won't make urine if one is dehydrated:
"If your flight is three hours, typically by the
time the stuff you drink on board starts to find its way to your
kidneys (if it does--it won't if you truly need the hydration)..."

That's not so either, unless you're going into shock. Try not making
bold statements on health issues. You are obviously not qualified.

I was born and raised in a desert. You get thirsty when you get
dehydrated; it is an extremely reliable indicator of dehydration.

Physiologists know that dehydration can precede thirst.

Only under very unusual circumstances of rapid water loss, which are
not likely to ever occur while flying a general aviation aircraft.
Essentially, you have to be vomiting, urinating, experiencing
diarrhea, or perspiring profusely to dehydrate that rapidly. None of
these is very probable in an aviation context.

The military knows it in training troops. Pro sports teams know it. Serious
hikers know it.

None of them are pilot GA aircraft, however, and there is no
comparison. You're no more likely to dehydrate significantly in an
aircraft than in a car.

All plan appropriate water consumption based on planned
fluid losses, not thirst.

Only when TBW losses are expected to be extremely rapid. That does
not apply to general aviation.

You also imply in another post in this thread
that the kidneys won't make urine if one is dehydrated:

They will concentrate as much as they can. If dehydration is extreme,
however, they will go into acute renal failure. Again, however, this
is never likely to occur in an aviation context.

If it burns when you urinate, that's one sign that you are seriously
dehydrated. A simple test is to make sure your bladder fills every
3-5 hours, and check to make sure that your urine is not brightly
colored. If it is lightly colored and you urinate at least with this
frequency, it's unlikely that you are significantly dehydrated.

That's not so either, unless you're going into shock.

It's normal physiology.

Well, it's normal that normal physiology is normal, but you don't know
what that normal is.
I'm not going to address your ignorance further for the same reasons
that others have given up on you. I only responded to suggest to anyone
interested in the topic that they not take those statements of yours
that I quoted as factual. They should go read an authoritative source
about a topic that can be vitally important to some. As for you, who has
never even had a flying lesson let alone piloted a plane, you even have
the hubris to suggest to an ex-fighter pilot how to recover from a
stall. LOL

Don't bother to argue with him, he knows everything about anything, and is a
world expert on the whining backchat.

I'm avoiding his assertions regarding physiology scattered throughout
this thread. He displays in them two bad proclivities. One is to run to
the Internet to get a superficial and often erroneous impression of some
topic and then post in an authoritative fashion based on that info. The
other is to not be willing to alter his misconceptions if challenged. He
digs himself further into a hole and gets more and more ridiculous.
