When ever you need to and before u put it away for the year
There is a holding tank. When the plane gets to its destination they empty it.

A place to empty your holding tank.
That is impossible. There has to be a leak.
Empty it, unhook the hoses and wires then unbolt the straps holding it on.
An RV toilet is designed to be mounted over a holding tank. They use almost no water which at first might sound appealing, but unless you have a septic tank under your bathroom it would be bad news for home installation. Unless modified, an RV toilet would not be able to get the solid waste to your home septic system. A home toilet uses the force of the water to move the solid waste to your septic tank. Look for a low flush toilet or a composting toilet instead.
If the holding tank is full you can flush it just once. Further flushes will have to wait until the holding tank is again full. If the tank is empty- no. If you have a way to refill the holding tank with water again, you can flush one more time for every time you refill it. When our water was going to be off for a time, I pre-filled the bathtub with water to use for this purpose.
A pumpout station offers what kind of service for boaters?
The easiest way is to disconnect the fuel inlet hose at the manifold, or filter, connect an 'extension' to another holding vessel, and then jumper the fuel pump relay and allow the fuel pump to empty the tank. You can attempt to siphon the tank, but that is dangerous, and will not get all the liquid out (if you can even get it siphoned). The only other way is to remove the tank, and empty it.
what you do is you wait until your teacher says you should empty your tinkle tank after lunch!
