Video How to Pee While Flying

[201er]

In a Mooney, pretty just much like that. Piss bag or Jose’s fancy vacuum piss hose.

The F-16 guys have to make instructional videos about using a piddle pack so they don’t lose control of the aircraft again. And again.  Very embarrassing.

And lest you don’t believe me…

Hmmm...now I'm regretting deleting my vacuum pump.

So, is that what a wet vacuum pump is for?

Talk about P-Factor.

I believe in some other aircraft a Condom catheter is used, all you have to do is let it go, it goes into a bag of course. U-2, maybe the SR-71?

Back in the day aircraft had a venturi fitted like ones used to run instruments just smaller and a very long thin funnel, it pulled a slight vacuum.

We removed them in Army aircraft in the early 1980’s. I used to keep one of the funnels on my desk as a Sgt. none of the newer guys knew what it was and most would try to play it like some kind of horn, that’s when I’d ask them if they knew what it was.

It was an unused new one, I wasn’t that mean.

I would never have believed it, but AC Spruce has the funnel

I have had several King Airs with pilot relief tubes under the seat, hooked to a venturi on the belly.

Yeah, the PA-46T I manage has one too.  Picture an aircraft pressurized to 9,000’ but flying at 25,000’.  When you squeeze the little handle to open the valve on the funnel, pressurized air shoots out through the funnel causing a cold breeze.  It’s not ideal.  Well, that and the POH warning about severe corrosion risk of urine, so the pilot has to dump like 2 gallons of baking soda/water through the thing immediately after the flight.  I like bags better, but basically, I just hold it.

Why look that far? Whoever gets Monroy’s Mooney is going to have his used piss tube included no charge!

Sketchy. Both articles mention undoing lap belts to reposition as well as ejecting. Did these guys get their belts back on or can one eject without a lap belt?

Well 2 things…

Fighter pilot stories only require 10% truth, so either way we’ve met that threshold…

Second, you can probably successfully eject with your lap belt undone.  The lapbelt is part of the seat and is separated at some point during ejection before you separate from the seat.  Shoulder harness and crotch straps are part of the chute.  You need those.  Ejection is like a simple 27 step process.

Actually I know of at least two other pee/ejection scenarios.  One was on the ground.  Both lived.

You can.  There may be some "undesirable" dynamics between your butt and the seat that may result in serious injury.  But at low level/low speed (<14,000 and 450 kts), one of the first things that seat is going to do after stabilizing is cut the lab belt and kick you out.  If you're above 14K you're to ride the seat down until it kicks you out...that's where the lap belt is essential.  Otherwise the "only" straps that really matter are your parachute shoulder harnesses.

It's so difficult peeing in the F-16 that in the 250+ hours I had as a back seater, I just held it.  This included 6+ hour sorties.  Once I really had to go, I was wearing a poopy suit and couldn't for the life of me get the zipper open to pee - I almost just went in the suit.

We had one of our pilots that would give about a serious 30min lecture on how to pee in the F-16.  He would get to the gals in the unit and say, "You girls are on your own.  I don't have a clue how that works"

So, indeed, peeing in the F-16 is so difficult that they have instructional briefings and videos on the subject.  Nevermind a song about the subject:

We removed them on Military aircraft due to corrosion
