With a 5 hour airplane, that can hold up to 10 people, some of whom are over the age of 60, that takes minimum of 30 minutes to divert to an airport, it is pretty much a requirement.


TJs are fantastic and what I use in the pilot's seat. But they are only good for certain uses.


The bags are not transparent. It just looks like a little garbage bag. It is not particularly gross to remove and toss. The pellets do a great job of neutralizing odors.

It is WAY less gross than cleaning up after a passenger has an "accident" and you provided them no options. That will be an experience the passenger will not soon forget and will color their willingness to fly with you again.

My system scores as low on the gross index as I can make it, both for the passengers and the crew. It also weighs less and puts the airplane at less risk of corrosion.

Mine has 2 reservoirs as well (I can take some pictures and see if there is name/model info on it). It was installed as part of a Sierra cabin mod so it's not stock. They removed the rear lav and dividers, installed a rear bench (3 belted seats but the middle person needs to be small) that is pushed back a foot or so from stock. This really opens the club seating area so people aren't banging knees but there is still plenty of space behind it for cabin baggage. Then they added a belted potty seat across from the door. This seat abuts the barrel seat so it creates a 2-seat divan.

This does make the potty an emergency device since you will quickly become very close friends with everyone in the cabin if you use it. My plane is for personal use so everyone on it are friends or family. I tell everyone about the potty situation ahead of time and so far it has only been used once and then only for #1. That was a family-only flight fighting crazy headwinds from Savannah, GA back to Oklahoma. I dropped down to LRC to stretch fuel and it took forever. I have since learned about the tables in the Operating Manual that gives optimum fuel consumption based on temps, winds, etc which are often faster than LRC.

I also "converted" it to dry in that I removed all blue juice, cleaned and dried the reservoir, and installed a "Double Doodie" bag into the reservoir while flaring the opening before lowering the seat. It still has a bowl which gets dirty if used but I haven't yet taken a saw to remove the bowl and make it like Mike C's (I would need a bucket like Mike's as well to cover the vertical gap that the bowl currently covers). I keep a container of Smelleze in the refreshment center drawer. I believe it is the same stuff that is in disposable diapers. After going, just sprinkle a little into the bowl and it neutralizes any odor. Disposal is nice since it is right across from the cabin door. Just lift the bowl, close the bag (it comes with double ziplock closures), and drop into the FBO trash can.

All that to say I only have a 3 hour bird at MCT so I haven't needed it since that one flight. I do keep some TJs as well for me and if anyone wants to use those instead of the potty.

Something Mike and I definitely agree on, getting rid of blue juice!

Ah, toilets. My favorite subject. The bane of all small jet owners.

I am very surprised to hear of a two-reservoir solution in a 501. I didn't think you could make one that small. How many flushes does it give you?

I'm moving forward slowly but steadily on my dry-flush solution. I do have a prototype that fits in a King Air toilet frame. It doesn't replace the seat cushions, frame or belt, so it's still a legal seat. No muss, no fuss, and NO BLUE GOO. Right now it doesn't have enough capacity but version 3.0 should have enough for an average flight. It has enough space for two uses; I'm targeting a minimum of five. If your flight is "above average" it can be changed mid-flight without looking at or smelling the aftermath. I hope to eventually have one for every small jet if I can make the STC broad enough.

Mike's solution and any other dry pellet/kitty litter solutions leave the aftermath of the previous user visible and smellable for the next user. Mine makes it disappear. Mike's is cheaper, but your wife will like mine better.

Here is my toilet story I may have told before:

It was an early morning flight from Wichita to Aspen in a T210. Around the Ks/Colo border, one guy needed to go No. 1. Since a stop would probably cost us an hour, looked around and found the plastic bags the oxygen masks came in. He used one, we slowed down, opened a window, and threw it out.

Keep us posted! I can imagine something like those diaper pails that after each diaper your cycle the handle and it seals the previous one in a bag....

Wise to move slowly on this problem. Can't wait to learn more about that Jim, sounds like some good sh!t.

It isn't well lit back there, you don't really see the bottom of the bin, the pellets do a great job of soaking everything up, and the smell is mostly contained. It hasn't been a problem. For one thing, it is hardly ever used twice on a flight.


I'll be curious what the mechanism is for that and how it avoids having to be cleaned.

It's hardly used twice on a flight because no one wants to use it the second time.

My eyes were opened when mine got used 3 times on a 1.5 hr flight, and another time on the ground when the rental car was five minutes late.

Boy, this thread has really gone to crap!

No. It was is finally getting interesting for those of us that can’t afford a Mustang!

Charles, my wife and kids (ages 7,5, and 3) use the toilet in our Mustang nearly every flight. It's a game changer compared to the Meridian. Super easy to clean. Just change the bag, throw in some gel powder and off you go. Literally 60 seconds to handle the mess and it's across from the main cabin door.

I could live without the potty, but I do a lot of 2 to 3 hour legs and it makes things much easier on the passengers.

How many "flushes" are in the jiffy pop looking piece?
