Further development of the new SAS for aircraft

[Spanier]

As of now the SAS system is perfect in handling rockets, stations and probes. But it sucks in stabilizing aircrafts. A whole lot of them doesn't fly smoothly but still shake with the all known wobble, because damping mode doesn't work as it should. Instead of bringing the amplitude of oscillation down slowly, it sometimes even produces this waving movement. For example, consider the B9 YF-28 Haldeman flys extremely stable on it's own, but when you kick in SAS and try to turn it, it flys as if it had parkinson afterwards (tested with FAR). I think the algorithm to adjust the differential equations for the damping could be optimized for planes.

A feature for optimizing long range atmospheric journeys the also SAS lacks is horizon orientated stabilization. As of now, a aircraft cruising above Kerbin slowly but steadily pulls up as the surface curves away beneath it.

Anybody also feels like there still is some potential to put work on the SAS?

Remove FAR, THEN complain about SAS on planes...

I wouldn't worry too much about how spaceplane mechanics work for the time being. Eventually(hopefully in one of the next couple patches), they're going to have to rework all of the spaceplane parts, how they function and the whole aerodynamic model in KSP. Just gotta wait it out 'till that happens, I guess.

It also seems to depend on the craft, the B9 BRV-4 Heinlein, for instance shakes when SAS is on, but the B9 SCDV Vonnegut does not.

Solving differential equations isn't a question of mods, the SAS should be able to realize the inertia of your craft and the torque it can apply to it. From that it could calculate the hysteresis the craft can be stabilized best with.
