Your ADF will probably have 360 at the top. So lets suppose that you were heading due south in nil wind your heading would be 180 and as you passed the NDB the ADF would read 270. Then if you turn left onto 166, the ADF will move clockwise by the corresponding 14 degrees and read 284. Therefore as you pass at right angles on a heading of 166 you'll see 284 on the ADF.
But it wouldn't be at right angles to the NDB in that case would it? Because your track is actually 170M. I give up, I hope there aren't too many questions about NDB. VOR I'm absolutely fine with.
