Notice that the mode indicator is only in the middle, far from the value it's indicating the mode of, but in the cockpit picture in the article ( http://blog.martindoms.com/wp-content/uploads/2011/01/IMG_82... ), you can see that there are actually two mode indicators, one in the same position as the one in the study and one right above the value where it should be. A quick Google of other cockpit images shows that the plane does have two. I wonder if this was an oversight?
