system. A chap from Germany called Alexander Kappes (cc'd) got in touch with me a few weeks ago and has written the start of Approach control. At the moment tuning in to a valid approach frequency (Dortmund or East Midlands) should result in vectors to a spot about 3 miles from the active runway, and a telling off if you stray too far from the correct course, in the console window. He seems to know what he's doing so expect this to improve rapidly!! I've added a rudimentry AI manager and a hardwired Cessna at KEMT on the runway - I'll remove it before the next release if I don't have it flying by then. There seems to be an issue with framerate which drops alarmingly when looking at it - I've a feeling that I've possibly created several Cessnas on top of each other, but am not sure.
