The heading line is a line from the own ship position to the outer edge of the radar dis-
play area and appears at zero degrees on the bearing scale in HEAD UP mode. The
orientation of the line changes depending on the ship orientation in NORTH UP and
True Motion modes.

own ship, press and hold the HL OFF key, or place the cursor on the [HL OFF] box in
the InstantAccess bar
