andy	2f2d486778	Curt noticed a while back that YASim was producing alpha and sideslip ... values that were angles between the aircraft's orientation and the global velocity vector, not the airflow velocity. So the HUD velocity vector was wrong when the wind was non-zero. Fix that.	2006-08-28 17:24:34 +00:00
andy	439a9fa1e4	Minor API changes to support the new sg_geodesy implementation. A few ... places now use sgCartToGeod() instead of rolling their own approximation. And YASim is now using exactly the same 3D coordinate system as the rest of FlightGear is.	2003-12-19 02:42:32 +00:00

curt	5b84ae51a5	Initial revision of Andy Ross's YASim code. This is (Y)et (A)nother Flight ... Dynamics (Sim)ulator. Basically, this is a rough, first cut of a "different take" on FDM design. It's intended to be very simple to use, producing reasonable results for aircraft of all sorts and sizes, while maintaining simulation plausibility even in odd flight conditions like spins and aerobatics. It's at the point now where one can actually fly the planes around.	2001-12-01 06:22:24 +00:00
