Hello! I'm experiencing issues with the IniBuild A320 and A330. During flight, the autopilot disconnects on its own after some time. I have already completed the throttle calibration, but the problem persists. I'm relatively new to this and am using an Xbox controller.

Hi @Nillerg0d

The AP can disconnect for a variety of reasons, the most common being due to a constant control input (noisy axis) or due to the MSFS AI Pilot assistances causing a conflict.
 

For the former, check your controller axis and add a relevant "deadzone" in the middle that covers the noisy area.

For the latter, please ensure the assists mentioned here are disabled: 

Other than that, please provide screenshots/videos of the instances where you're noticing this issue so we can have a better idea of potential causes.

Thanks!

Turning off the assists seems to have fixed the issue. Thanks 🙂
