The OBS has no meaning to a CDI when using a localizer.
It's left or right of the localizer beam where "left and right" is
defined as looking inward on the front course. It's only when the

back course) that things are "reversed."


This is not true. The OBS ring has no effect on the needle, but it
certainly has meaning.

If the OBS ring is set to the inbound (only) localizer course, it can
be interpreted exactly as the equivalent VOR course.


Exactly. Glad to see someone else using a more sensible interpretation.
