Hello there,Flying Russia (again), I tried to force the plane with a FL348 (10600m) then FL360 (entering poland) using the SFL... But the second climb happens immediatly, like if the FMS ignore the /SFL command...Look at the screenshots below (I fly FL348 with a FL360 climb ahead on the route all the time).I even tried to force the Flight Level without success :Is this normal or do I made a mistake ?Regards.

I think it means the FMS has calculated that it better at FL360 than lower, compare this with the optimum/max numbers on the cruise performance screen at about the time you arrive at the step climb. That should confirm my hunch.
