Yes OS: Windows 11 | CPU: i7-7700k | GPU: GeForce RTX 3070 | RAM: 16GB DDR4 During atmospheric flight, SAS will overcorrect in a way that seems most prominent in roll, but also will at times be strong enough to destroy craft on the runway. Wing authority below 10 deg. seems to be the only method of correcting this in-flight, and while reducing control surface does work to a degree, almost all aircraft (especially if not perfectly balanced) will experience cascading stability failures that do not occur in manual flight.

Can you describe the problem a bit more? The planes are rolling for no apparent reason? I don't trust SAS at the moment with how control surfaces will go out of control soon after take off.

The issue with SAS has been acknowledged by a dev recently although I can’t remember off the top of my head where. The issue is that it causes very large oscillation because it always applies 100% inputs in all instances instead of smaller inputs for smaller deltas required. A perfect solution would to have SAS get to a “critically dampened” state in every situation, although that is likely not computationally efficient.
