That makes sense -- thanks. So, here's my near-term YASim wishlist, which is pleasingly short: - wing washout - turbulence - steady-state starts with non-zero velocity and/or in-air - respect runtime property changes (i.e. new altitude or location) All the best, David -- David Megginson, [EMAIL PROTECTED], http://www.megginson.com/ _______________________________________________ Flightgear-devel mailing list [EMAIL PROTECTED] http://mail.flightgear.org/mailman/listinfo/flightgear-devel
