Thanks for your fast reply!
There's a file inside the aircraft folder (from memory; have no time to look into that one for now), I think it's the aircraft.cfg, where a lot of the items that should be saved, are assessed too. Would it be practical to change some of them (first of all the basic options in the tablet) there to not have to change them everytime with a new session in the sim? E.g. hide the GPS, force the registration, don't fill the payload automatically into the CDU. Or would that lead to some other undesired consequences?
I will observe the little missmatch with the coordinates in the SDU. Yes, maybe it's a rounding problem.
Thanks for the fast support. The Starship is wonderful!
