FSUIPC... well, I never really tried to program it that way. Have to look and give it a try. :-?
Would be nice if all panels would have something like a fuel transfer and feed subpanel, though it's very rare among freeware. Even rarer than full autoland.

I remember the only panel I've tried with a fuel transfer (that on my system only showed to work, but in the end never really transferred anything and I had to do it manually in the window as above) was on the original panel of the SGA DC10, and then, it worked only between the front and rear central tanks, the wings were only displayed as a quantity of fuel remained.

Not really a fan of the Bae146, though I know there is a very good panel that might simulate fuel transfer, the freeware models of this plane around have a tendency to keep their noses too sharp in the air at low speeds (even more than the POSKY 747's, and it's saying a lot), thing that make every manual landing a nightmare, and even ILS are not at all comfortable (how can you flare at all if your plane descends the glide with an AOA a little shy of 10
There's but one real cure for human stupidity. It's called DEATH.
At the moment mourning the assassination of sarcasm and irony for the good of the "higher".
