DFC. Can I take you back to the original question. Magflip says it doesn't seem to matter whether the arrow is pointing up or down while intercepting VORs. He is therefore using an HSI with a serviceable, slaved card. In this situation, the BB will show a correct demand, and enable interception of a VOR radial whether the arrow points at QDM or QDR.
In the case of the ILS, if you have the arrow pointing away from the runway, it WILL show a reversed demand. We use this fact to fool the HSI into giving correct demands for a BackBeam ILS.
In the ILS case you say you are concerned only with the a/c position, not the way it is pointing. I am describing the real life situation where one is concerned with both parameters.
Perhaps if we pursued this long enough we might find that we agree, but are expressing it different ways. But whereas you say bluntly "That's the wrong way round!", I say CRM-style, "consider another way of looking at it."
