D Controller
A few years before I started as a cadet on 39 Course, a system was in operation where the area procedural controller sat miles away from the radar controller. An example of this would be at Scottish Centre where the procedural controller was at Redbrae and the Radar controller at Gailes. I think the same was in use at Preston. The procedural controller was always known as the D controller. Can anyone tell me why and what the D stood for?
Thanks
