(I can't seem to find the answer to this anywhere. Prepping for an interview.)
If we have an offset localizer (up to 3 degrees), when the value is positive (e.g, 1.75 deg), we'd expect to see the runway on which side of aircraft?
I'd assume a positive value means the final approach course would bring you in just to the right of runway, and the runway would be left of center from the cockpit perspective. But I can't find the answer anywhere online. Thanks for the help.

It was a bad question, hence it's construction, and did not deserve a sserious reply.
The notion of abandoning localizers because they are "outdated" is equally idiotic.
However, when considering where the runway will appear in the windscreen when breaking out, as noted before, it depends entirely on winds aloft. If there is no wind, regardless of whether the runway is offset, if one is on a localizer, the runway will appear at 12 o clock, but angled slightly away. Any significant wind aloft can put the localizer at the 10 o'clock or 2 o'clock positions, or greater, and that is a far more important thing to consider, than the ramifications of an offset localizer on a calm day. Winds aloft determine where that runway will appear when one breaks out, and where one should be looking.
As for imagined or invented terms such as "positive or negative" with reference to the localizer, those serve only to confuse the reader and provide no useful information with an explanation as to what the questioner means.
