So I had a little question.
Yesterday I was flying a 172 from Thessaloniki to an AF base in Athens. I was using a VOR to navigate, yet had a small problem. So, as the flight was about 2 hours, I needed to use AP. I tuned into NAV1 for the VOR, and made sure that my source and everything else aligned. Then, I engaged NAV after hand flying for a few minutes (I had double tapped the CRS.) Instead of flying to the VOR, the plane turned in the direction of the light blue thing (forgot the name)
How do I stop this from happening?
