A VOR radial is a magnetic bearing transmitted by a VOR station, representing a magnetic direction from the station.

No, the heading has no effect. Position relative to the VOR changes based on your radial, not your heading.

Answer 4

The OBS is used to select a radial and center the course deviation indicator (CDI) needle, which tells you your position relative to the selected radial.
