VOR navigation is indeed a hard to absorb in flight simulator at first (and probably in real life for that fact! ;D) Ive went from flight simulator 5.1... through fs2002... through various combat flight sims... and for some reason, it took me so many years before it hit me on the head on how easy the concept was (For some reason, i discovered it in Lock On: Modern Air Combat)
I like to think of VOR as this:
1) The VOR station is like a waypoint
2) by selecting a heading on your OBS knob (or your course knob), you select a radial... Kind of like a road..
I know step 2 is the hardest to understand, as I have trouble explaining it myself. Say you want to fly a towards the station at a 270 degree course... select 270 on your indicator and imagine a big line drawn across the VOR station... Its kind of like a road to follow
3) Then you intercept the station at an angle... and once your indicator centers... fly heading 270 (just using the example from #2) and you will be heading towards the station.
4) To always means your flying towards... from flag always means your flying away from.
5) Always think about the VOR station in relationship to your aircraft... and always remember, the radial you select on your heading indicator is relative of the station!
to help you out, ive also searched out a VOR simulation so you can better grasp the concept of VOR navigation
