I'm testing, so far so good
It's a very complex way of doing a very simple thing I guess.
The plane has 2 wing tanks that feed two collector tanks, one per engine.
But also, for gained range (up to 4600 nm -- which is mind blowing for a plane her size) it carries extra auxiliary tanks.
The plane carries two pumps one for each wing tank feeding the collectors, from where fuel is injected to the engines.
In normal operation, the plane cross feeds the wing tanks from the auxiliary tanks. I have it emptying these at a given order; trying to keep balance throughout. Crossfeeding also implies that both wings feed the injectors. There's a knob in the plane that cancels the Xfeed of wing or right tank when there is a unilateral fuel imbalance you can use that.
in case of a AC electrical reduction the plane automatically switches tot eh AC Pumps 1 and 2. This cancels all crosfeeding. Now the fuel goes from left wing to left collector to injector, and Right likewise (unless the knobs for AC are in OFF).
Finally, there is a DC pump. This one works if there no AC electrical power. ie, it feed the APU from the right wing only, or it feeds both left and right collectors from right wing only. If you get here on midflight, your life is already stressful on other levels, not only fuel.
The xfeed and pumps are what's currently simulated in that code.
Electrical is very rudimentary still on the plane, so I need to learn howto make these systems before thinking electrical.
Other things on fuel systems still to be made: ie, the fuel does not have temperature yet. Trying to figure out how to calculate that. I was thinking it might be related to external temp, and oil temperature. But oil does not have temperature yet either. so that's that. Stuck duck.
Other things on the fuel systems still to be made relates to rework the eicas announcements data.
