Relieving in flight

Put the catheter on carefully on the ground before you get in the cockpit is my primary advice. I also have an overboard tube that is attached to the inside of the main gear door so I have to put the gear down to dump. I only use this to dump a filled bag as I don't really want the gear down for the time it would take to pee directly overboard. With the bag always attached, you just pee at your leisure without a big production. I generally agree, dumping overboard is to be avoided. If you do, make sure to rinse off all the fittings in the tail/rudder upon landing. |

Watch out for sunburn, too!Â* I carry a couple of rags for that and they
double for cleanup, if necessary.

A couple of us in Idaho have put a tube from the cockpit to under the rudder. Use a funnel with a small electric pump under the seat pan that pumps fluids out the back with no residue on the glider. Only draw back, have to run some RV antifreeze through the system after each use to keep the system from freezing up. Other than that issue the system works well and no clean up of the aircraft.

Buy one of the two Rumpf Super Hp18's with Udo's built in removable
pee bottle at the base of the instrument panel! Best system I've ever seen in a sailplane. Alternatively use gel pee bags. |

This site has a lot of info, including a posting I wrote for RAS many, many years ago: http://aviation.derosaweb.net/relief/
Some interesting updates in the recent postings, including reusable catheters. It's annoying to discover the day before leaving for a big contest that I'm running low on the adhesive type. The ones I've bought the last few years aren't latex. They're clear plastic of some kind (silicone?) and seem to stay on much better (e.g., see 9B's comments about cold). Still, I carry at least two for every flight. I, too, apply them before launch. Loose clothing works makes it easier. If I were to do it over again now, I'd probably go the UH route. That said, when we removed the rudder on my 25-year-old ASW 24 last winter, where I've had the dump port mounted on the lower aft corner of the gear door for that long, there was no corrosion. But having to lower and then raise the gear each time is a hassle, including listening to complaints from pilots below you in a thermal. The older I get, the more I drink to stay hydrated and the more often I pee.. I didn't realize anyone was still littering the countryside with plastic bags. Chip Bearden |

I'd be a lot more interested in hearing any women pilots address this, because I think the problem for guys is simpler and better understood. There are any number of devices on the market for female athletes, hikers etc etc Williams Soaring has a system on their website at https://www.williamssoaring.com/cata...-supplies.html ; about a third of the way down the page - 'female relief systems'. |

Ok guys, this has probably been covered in older posts but what are you all using regarding urinary relief on long flights? Ive used gallon ziplock bags in the past but whats your experience with cathaters. What brand and how are they. Here is a different idea that some of us are using: put a large poly tube bonded through the hull (but cut flush) directly under and extending up to the intended area of use. Another tube that is a slip fit is cut long enough to extend 12-18" beyond the fuselage. On the near end of that put a Coleman refueling funnel used for camp stoves. To deploy, stick the smaller tube down into place - effluent sucked out and discharged well away from the fuselage. Rinse slightly with your water supply, then retract, remove, and stow. Advantages are it gets the pee further away, does not freeze, you don't have to glue it to your privates, and you're not carrying around a septic tank the rest of the flight. Here's the funnel. It's the right size, shape, and color! https://www.amazon.com/Coleman-20000.../dp/B0000AS5QB |

In addition to the sunburn preventer, I think also modify the bailout procedure to canopy, cath, belts, butt.
Having an easy way to keep fluids flowing is necessary to keep the brain working to stay up. To make this easy, I modified the transponder fin to have a 3/8 poly tube down the front edge. This is behind the gear doors and a bit to the side, so it doesn't seem to streak the glider. It stays hooked up all the time so there is no hassle factor. There is a tee in the line with a blow tube usually clamped with hemostats. This permits blowing out the tube to the back if there is a worry about freezing preventing a second use. After flight, the blow tube is used to flush out the system. Overall, having a good, simple pee system is a definite improvement in flying. I find it amazing how many diverse areas of expertise flying gliders requires. That's part of what makes it fun. |

So, pick a number. I would never use my real birthday or year online.

Selection starts at 2018 and can only be stepped back. Would you believe 72 steps? JMF |

I wonder what they do if you pick 2018? Send you one into the future?
