it is absolutely dutch roll, caused by a misconfigured PID controller. there’s a community fix for it in this forum which completely resolves the issue. it’s a one-line edit to the 208B’s config file, and it was released before SU1, but curiously although we’re now into SU4, the devs seem completely incapable of implementing what is actually a very simple fix.
the fix has been uploaded here: https://flightsim.to/file/94786/cessna-c208b-caravan-autopilot-roll-fix
fix details:
I checked the rollPID numbers in the ai.cfg for the 208 and the numbers were very strange compared to the other turboprops.
The numbers in the beta 1.5.13 are rollPID = 0.1, 0.5, 0.1, 8.0, 100.0
P is very low
I is high
D is very low
For example this is the numbers for the tbm930
rollPID = 1.5, 0.1, 1.2, 8.0, 100.0So I made small mod using the numbers below:
rollPID = 1.2, 0.1, 1.0, 8, 100.0And it fixed the roll issue.
Happy flying without falling asleap
