Describe the bug

Did a flight RJAA - KJFK noticed that simbrief gave me an exact fuel for my block time (with ETOPS, Alt, etc). It shouldve been much higher. so, before i took off i threw on an extra 20k LBS (making it exactly 180K) and im down to 8.2 for EFOB on landing. This needs some work on the simbrief aircraft and or the aircraft itself.

Expected behavior

SImbrief should've given me something well above 180K LBS fuel instead of the exact block fuel.

Steps to reproduce

1. make and generate a flight on simbrief
2. Load that fuel via efb
3. brief and look at your flight route details via navigraph charts (weather, wind barbs, etc)
4. you will notice that just generally eyeballing it was far too low.

What about the simbrief airframe used?

I have the same issue, and I use the SimBrief airframe you've provided in the installer and on the website.

I have the same issue, but i believe it's a problem in the aircraft's fuel consumption that is too high compared to the simbrief profile, but also, and it is the real issue, inboard fuel calculation:

I did a 7 hour flight and had a fuel reserve for 1 hour, the real flight time was very close to what simbrief gave me, i had wind uplink activated, so the wind should have been taken into account in the fuel consumption calculation for arrival EFOB and flight time.
In my simbrief dispatch, the trip fuel it gaves me was 41.5t, and at arrival, the aircraft did consume around 48t, so ~15% more of fuel consumption.
During the flight, my arrival EFOB was continuously decreasing, same thing for my fuel reserve.
So the fuel consumption seems to be higher than the one it is taken for onboard calculation and simbrief profile.

I also did another shorter flight: KDEN-KATL, so around 2,5 hours, and i noticed the same issue.
