Ok... No, let me ask the question this way:

First I would like to confirm this:

1) The VOR 1 and VOR2 displayed on that photo are coming from the VOR antenna. So when we see VOR1 ---, it means that the VOR is not in the range of what can "see" the antenna.
2) We say to the ELAC: we are here. We want to go there. Right?

Now comes my question: when we enter a CRS and the frequency of the VOR, we tell the plane that we want to be in this radial of this VOR. ELAC knows where we are (GPS) but it should know where is the VOR. Because when we enter x HDG, it means that we want to be HDG x from where we are. So the ELAC knows where we are.

So for a CRS, is the antenna VOR connected with the ELAC to tell him? Or has airbus peogrammed each and every VOR in ELAC so that it knows directly where to go?

Thanks
