Hi, I'm fairly new to XPlane - flying for about a month now. However I noticed some strange behavior in the area of navigation. At least I cannot understand what is going on. For some reason I'm having a real difficulty to track a VOR. When I intercept a radial and fly the corresponding HDG the CDI shifts nevertheless, to quite a considerable deviation. One way to mitigate is to fly a HDG which is a couple of degrees off. For example to track radial 286 I need to fly HDG 283. Does anyone know what could be the reason for that? Another problem I saw - there is some radial mismatch between the X-Plane VOR radials and HDG info from sites like Skyvector. I know that X-Plane does not have the most up to date data. On the other hand neither does Skyvector, so how do you navigate? I'm flying in CAVOK conditions, no wind, so weather is not an issue. I'm also using AP so nothing to do with my beginner flying skills Really appreciate your help. Thanks!
