Concorde MSFS SU9 fuel transfer bug?
@dc1973 and thanks Atebis for your answer.
I haven't flown Concorde lately because I was stuck with this.
I followed the 2 procedure versions the manual and the checklist.
Now sometimes the game has to be started and restarted and things will be fine.
I will jump into the concorde cockpit, cross my fingers and try again 🧐🤔😏
All the best
