Hi,
I can now be more precise :
When I desinstall and reinstall the AC, I can enter everything to fly (init, FPetc...) from FMS1, and everything is OK.
After the first flight, I have to enter the informations on FMS 2, otherwise I have no active FP.
At this time, I don't know why.
Any idea because FMS 1 is easier to use than FSM 2.
Thank's fro an ansxer
