I recently did a flight from LA- Manchester (EGCC) in the a330, i calculated everything like the fuel thru simbreif, imputed the flight plan and it's saying i don't have enough fuel. I tried this on another flight with the a330 and once again it was not enough. I have never had a issue with simbreif so im wondering is this a user error by me? Id really like to fix this so i can do long hauls again I also occurred a issue with the rudder as if it wouldnt turn at all which was strange as all chocks were off and nothing was connected e.g GPU.
