Plane Toilet. How Things Work

Quite often in everyday life people, far from aviation ask me a question “Is it true that on the plane like on the train everything (from the toilet) goes out?” Seriously, if we can see the tracks through the toilet hole on the train, it’s probably not working the same way on the plane. Does it mean that the products of our life activity don’t fly outside? First, let’s see what we have on the plane to keep everything clean and hygienic.
The water-supply system is filled up with the pure (drinking ) water from the car before the flight. You can drink this water right from the hose (tube) (I’m not big on that though). Before the flight it goes to the plane’s back. After that water goes to a boiler (so passengers can use it for tea), wash-basins and other sinks.

Now let’s talk about lavatories and toilets.

In the A-320 the removal of waste from the toilet happens with the help of vacuum. Basically, all the crap is sucked to the back. I’m not sure how real it is to be sucked to the toilet, but I wouldn’t recommend trying it yourself, because theoretically it is possible.

In the TU-154 there is a filter in the waste back which keeps the big pieces (yuck), and the filtered stuff goes up again to flash the toilet. It works the same way as a dry closet and has the same smell as well.

Sometimes passengers drop the stuff to the lavatory and then technical problems begin. Anyways when something is dropped by mistake it is understandable. But people who put tampons and pampers!!! All this becomes swollen and kills the system. Passengers, please use the trash cans, there is the reason why they were made.

So when the plane is at the destination airport the car with the big crimped hose serves toilets. The back is getting empty through the hole to the car.

There is a container in the car and it carries it to the certain place. It is a horrible view with a disgusting smell, which looks like a swimming pool. At this moment the passengers of the flight are remembered and the desire appears to drop them now to this pool.


Hopefully I was clear enough to cover this delicate topic.

wow..thnx for explaining!
i thought that this worked differently
imagine takin the !”§$/( out of A360
I’m usually using toilet for masturbation and i guess author of this “How things works” is also toilet fetishist.
in olden day toilet dumps directly out of plane, no need for silly vacuum system.
If it goes directly out of plane, the differential pressure between inside and outside the plane will suck you too..
I thought they just throw away everything at a high altitude. Not a bad idea though.
the thing is, there should be a better way than to throw everything away
fortunately there are smarter people
Miss India just messes her pants, rather than going to the airplane toilet.
I know, I have sat beside her, unfortunately.
GREEN SHIT AMG
“if we can see the tracks through the toilet hole on the train”
…then it’s 100 years old, broken, or soviet.
Amazing, the stupidity of some comments in this blog… “in olden day,” “train tracks,” etc… What a large bag of f-tards you have in your stable ER!
The TU is a Russian design, therefore when nose the plane goes down, ass-end the plane goes up.
TU design this plane based on russian voomans.
Similar, I hope this is accomplished during flight, in order that cleanse all waste (passengers, and bodily fluids) from the craft.
In russia is not “Mile High Club,” is “One mile down club!”
You’re an idiot.
hahahaaha haahahaa…
