VOR Tracking question

Say you are on the 090 radial (ie exactly to the east of the VOR ground station), it doesnt matter whether you are pointing towards the station or away from it, the display will look the same. What does matter is what you have dialled into the OBS (omni bearing selector). If you have selected 090, the display will read 'from', because you are on that radial 'from' the station. if you now dial in 270, the display will read 'to', because you have to first fly 'to' the station in order to track up the 270 radial you have selected. Make sense? If not - draw a diagram, thats a big help.

I was making the example based on the fact you were tracking towards or from the station-rather than passing abeam or crossing a radial-but yes, my answer wasn't clear enough!

Of course what matters is the OBS-that's what determines the TO or FROM indication as you say.

Agreed-diagrams help a lot with VORs, and even more with ADFs!
