The markings in the centre are time/speed lines. In flight planning, you can put the line for your estimated groundspeed over your track, and see how long it will take you to get to a point on the ground. In-flight, you could put your time over a point on the ground, and read your groundspeed. The outer scale is a protractor. - Technical
