I have the CS C130 in FSX-SE and to activate the GPS flight path is very easy.
I have P3D V4.3 now and is very pleased that the C130 is included.
However, I cannot activate the GPS flight path although the panels look exactly the same. I do follow the same steps:
1. Mode selector to GPS
2. AP Power on
3. Engage on
4. Track on
And now the the AP should follow the GPS path, but nothing.
If I set the mode selector to Heading, it follows the Heading immediately.

Is their maybe a bug in the .cfg file?

Thanks for your help in advance
