I've been flying with VOR only a few times again towards airports that don't have a VOR of their own and I notice that the radials I 'calculate' using the navigation planner (which is a bit complicated to get done) often aren't correct. During my last flight it was way off and I missed the airport by a few nm's. I know VOR's aren't THAT precise but in P3D I usually got better results. I also checked the nearby nav aids on AirNav but the real world radials also don't seem to always work.
Are there other's here who fly using VOR only? If so, how do you figure out the correct radials to fly on?
