During a recent flight, I noticed that the aircraft’s fuel is burning significantly faster than expected, approximately 1.6× faster than the indicated fuel flow suggests.
The fuel flow indications on the ECAM appear to be correct, and the aircraft also reports a correct amount of fuel burned. However, the FOB value decreases much faster than what the indicated fuel flow or fuel used values would support. In short, the FOB is dropping faster than the engines are actually consuming fuel.
This problem seems to be in all flight and ground phases.
I'm on the current SU4 Beta
