There's also more to the problem. If we're restoring a saved flight then everything's fine, since all of the FDM state is already valid. If, on the other hand, we're starting in the air, then we need a general trimming routine like the one Tony wrote for JSBSim and LaRCsim to avoid violent oscillations at startup.<ref>{{cite web |url=http://www.mail-archive.com/flightgear-devel@flightgear.org/msg09856.html |title= Presets menu|author=David Megginson |date=Mon, 18 Nov 2002 14:44:41 -0800}}</ref>|David Megginson}} | There's also more to the problem.

Yes, reset and save/restore are a bit broken in FlightGear right now. I'll try to fix them when I have a chance, but it will require a bit of refactoring (removing Curt's initial-state stuff, for example).<ref>{{cite web |url=http://www.mail-archive.com/flightgear-devel@flightgear.org/msg18869.html |title= Re: Helicopters: wow!|author=David Megginson |date=Mon, 24 Nov 2003 07:22:13 -0800}}</ref>|David Megginson}} | |||
