Is the Bendix/King KMD-550 airplane icon always oriented to the north?
According to the Source: 


  The bottom is for the icon in track up mode. For the North up mode, It
  Depends on the Heading. The fix icon should be placed on one of the 8
  positions (up left, up right, up center, bottom left, bottom right,
  bottom center). For example, if the Heading is 45°, the fix icon is
  placed on the bottom left part of the screen.
