i dont know where this would go. its been awhile since ive made a post like this. lately when i do a flight, it wont show how much fuel ive used. So it just sits at 0 kg used the entire flight. ive noticed its been that way for a couple of weeks.
There has been an on-off bug with the “Fuel Used” displaying correctly for a few years now:
If you need to know if (say for a VA PIREP) - take a note of the amount of fuel you started with and then the amount of fuel you end up with after you land and do the calculation.
