Autopilot disengaged as plane flies over South Pole

1) Background to the photos

When I flew over the south pole, the autopilot was disengaged. I’m not sure if this is a bug.

The autopilot was using magnetic course, which should not have a sudden change at the south pole. So, I don’t know why the autopilot was disengaged due to some sudden input change.

Hello!

This is a known issue.
The autopilot goes bananas at the poles.

Random question: does it have to do with magnetic heading when getting to the poles?

I don’t recall the root cause to be honest. Only that the solution to it wasn’t really as easy as one might think.

Intriguing because I tried KEWR-WSSS and flew right over the North Pole (no Santa Claus unfortunately) and my autopilot was just fine. Describe bananas @schyllberg

Seb means this.

Well, obviously but how bananas was the autopilot going?

About this much :)

No seriously though, it does go pretty crazy, when i tried the south pole, the plane pitched up and then stalled because of the sudden increase in the AOA, so rip that

We’ve gone so off topic that we are just talking about bananas now.

Is it becuase the fpl as it passes over the pole, the magnetic heading suddenly flips, causing the AP to get confused and attempt to suddenly fight against two inputs of data?
