There are two ways of doing this:-
1. Long press on your chosen VOR, select the VOR from the list in the pop-up window, and select
Track Waypoint. The position report at the top of the screen will then provide you with a continuously updated distance to the VOR and which radial your are on. When you see your desired radial appear in the position report, you will know that you have intercepted it.
2. Long press on your chosen VOR, select the VOR from the list in the pop-up window, and select
Track Radial. Enter the value of the radial you wish to intercept and hit enter. SD will then draw a narrow magenta line out from the VOR along the line of your chosen radial so that you can see when and where on the chart your track intercepts the radial. As before the position report at the top of the screen will provide you with a continuously updated distance to the VOR and which radial you are on.
Needles to say, you need to be in flying or simulation mode.
Hope this helps.
