Center fuel tank/pumps gamebreaking bug

Genista

If we turn on center fuel tank, the fuel tank quantity (visible on EFB) will empty very quickly, something like 2-4kg a second.

@genista What is the fuel quantity in the left and right wings when this occurs?

Mark

Yes, that sounds like intentional behavior. If the wing tanks are less than full, the fuel in the center tank will constantly be transferred into the wing tanks to keep them at full capacity.

@mark thing is, the wing tanks don't fill while center tank is emptying. 3895kg steady on each side. Does the link below works ?

In this video, only the APU is running, and I used simbrief load import in EFB to load fuel (for a fairly long route)

@genista Thanks for the video. We're investigating this.

Yes I confirm the same error already on the ground the center tank is depleted even when the wing tanks are full.

Hi, this is not a bug. If pumping fuel from center tank to wing tanks when they are full, excess of fuel will vent off the wings (!). Quoting an F28 Manual's fuel chapter:
