Heading not followed by autopilot after some time

[flying_David 0]

Hello everybody,

I recently purchased the C172 G1000 and yesterda also the SR22.

After some test flights I've experienced some troubles with the autopilot and the HDG mode.
When flying for a certain time after e.g. the departure, the autpilot is not following the set HDG anymore.
In the screenshot I selected a heading of 230° but the autopilot stops turning at 255° and continues to fly this heading - a deviation of 5°!
After 20 minutes of flying the deviation is even worse - Now I selected 215° as desired heading but the autopilot follows 209° - it seems that the deviation is growing by time?!

Can you explain that? Any ideas?
It only happens with those two Carenado planes. No problem with others so far!

Thanks in advance!

Best regards from Austria,
David

Maybe try pressing 'D' and see if that solves it.

It was an error by Carenado on some of their other aircraft defining the Heading indicator / HSI as the wrong type.
