If you use your rig a lot you will pretty much just know when it is getting full. But if nothing else when it gets full you will know when you flush. It is a pretty simple system. It may burp a little when you flush when it is real full. Eventually you will actually see the contents coming up the 3 inch line, hard to miss. Of course you want it to be at least 2/3 full when you dump so there is enough liquid to get rid of all the solids. Keep in mind the worst than can happen is you could end up with a little in the bowl. Not a crisis.

You must not have a flush kit installed.

We hook up the drain hose to the dump station, pull the slide valve for the black tank, allow to empty, then close the slide valve. Then pull the slide valve for the grey tank, allow that water to chase out the black waste in the hose. then close the grey tank valve.

to flush the black tank, we simply hook up a water hose to the flushing fitting and partially fill the black tank then empty again. repeat as required to insure the tanks flushed out.

I do not have a flush valve on my truck camper blank tank but I do have one on my 5th wheel Cardinal. But with either rig I still like to have 2/3 of a blank tank before dumping if possible. It just provides enough volume to push most the contents out. I also clean out with grey water after black water.

By the way thats one cool airplane you have there in your profile website!!!
