The CDI tells you which heading to turn to if you dial in the correct OBS.
Which do you think is more useful command: turn left, or turn to a heading
of xxx?

The OBS has much meaning to a CDI when using a localizer course,
if you just know how to interpret said meaning.

It has no meaning to the CDI, which after all is an inanimate
object. If
you
are properly trained it should have some meaning for you.

When I use words, they mean exactly what I mean for them to mean,
nothing more and nothing less.

Very well, what does the OBS mean to the CDI on a localizer?
