My 2 cents
Pretty sure that top left switch in the AP panel needs to be set to "normal"

In 2D panel with GPS selected: airplane drifts and ends up doing a complete 360 degree turn. You can see on the GPS that I am well right of the lubber line and the HSI needle is not deflecting

@ agfreeman ,

You mentioned:
"My 2 cents

Are you testing the C130 for this topic?

Or, were you just looking at my screenshots?

I tried it yesterday but needed to switch it to normal to get the AP to track to the GPS route.

Never got round to posting it as I was waiting for the op to reply with screenshots and noticed the OPs screen shot didn't have it whilst reading.

Hi agfreeman ,

"I tried it yesterday but needed to switch it to normal to get the AP to track to the GPS route."
You had not mention that in your first post?

You need to test it again.

Hello Martyson,
Yes, I did, thank you. I'm tracking the same problem in two different threads and should combine them into one. I tried your directions below and in GPS mode, it still will not track a waypoint. After updating to HF2, at least the 360 degree turn doesn't happen anymore. Now with GPS selected and trying to track a waypoint, the plane will drift about 90 degrees then straighten out and fly perpendicular away from the flight path. I also ensured I had normal selected on the autopilot.
