The A32NX & A380X Project are community driven open source projects to create free Airbus aircraft in Microsoft Flight Simulator that are as close to reality as possible.
FMS predictions take into account the FOB instead of the block fuel entered on the INIT FUEL PRED page before engine start. This is especially noticeable when refueling.
Expected behavior
The block fuel entered on the fuel pred page should be used for predictions prior to engine start. Once the first engine is started, the sensed fuel on board should be used.
Steps to reproduce
1) Fill INIT A, INIT FUEL PRED & Perf takeoff with any data.
2) Change the fuel on board via the EFB and observe how the EFOB at destination changes on the F-PLN page.
