The AP gives me some trouble. When switch it on for the first time in a flight I can switch on heading mode, so the AP is just following the heading bug and doesn't care about altitude or VS.
Then, when I switch on Alt Hold mode the AP is holding the current altitude and still follows the heading bug.
If I then want to switch of altitude hold I cannot do that because the AP switches to VS instead. There is no possibility to switch back to heading mode only. I just can toggle between altitude hold and VS mode.
In Just Flights Arrow this works riliably, so it is possible in MSFS.
However, sometimes I can get rid of altitude hold and VS by using an external button for ALT HOLD mode via FSUIPC. If I switch it on then off the AP switches off altitude hold without going to VS mode. But this works sporadically only.
