We'll take an example of what I have active right now. The aircraft is reporting 43000 KG (FOB) and 4300 + 4340 (FU), which equals 51640 KGS. If we subtract my OFP Block fuel (which was also entered into the aircraft don't to the milliliter), we get 51640 - 51608. That equals 32 KG. I am assuming this means I have 32 KG more fuel on-board than what is estimated. However, as you see in the image below, it still says 0 KG as the difference. I wouldn't report this if it was in Tonnes, however, I'm wondering if this is sensing down to the kg or if it is in increments, as if, say, it only reports it if it's 100 KG or every 100 kg. That's why I find it weird that it says 0 KG. It has been like this on all 3 of my flights, where I've also calculated that I am in a downward of -64 KG as a result of the calculation.
I'd like some information on that, or is this a bug?
From my perspective, it seems as if the system is not functioning. Not sure how other feels about this.
