Ah I see what you mean. Yeah, bugs aside, there’s a lot that could potentially be saved that isn’t. I figure some of that is to make things simpler when starting on the runway or in flight.
I share your taste and prefer more thorough saving, since otherwise pre-flight checks feel like empty rituals. In fact I’ve finally buckled down to write my own state save/restore Lua scripts for FSUIPC7, with the Starship being the first plane I’m doing it for. (I wish simply using the sim’s own .flt file saving worked better, but I’ve found loading those to have weird effects on complex planes.)
