There probably is a bug in the LaunchMFD:
Assume the following situation: Start the scenery "DG-S ready for takeoff" and set up the LaunchMFD for the target ISS.
The LaunchMFD indicates two requires headings, one in the northern direction, another one in the southern direction. The ISS moves in a southern direction, but the LaunchMFD decides do steer in the northern direction.
A time warp shows, that the LaunchMFD always makes a wrong decision concerning the required heading, as the target's groundtrace is west of the DG-S. If The target's groundtrace ist east of the DG-S, the decision is correct.
