Three different orientation options are available for system map displays. This allows flexibility in determining aircraft position relative to other items on the map (North Up) or for determining where map items are relative to where the aircraft is going (Track Up or Heading Up). The map orientation is shown in the upper left corner of the map display pane.

• North up ('North Up') aligns the top edge of the map display to north.

• Track up ('TRK Up') aligns the top edge of the map display to the current ground track.

• Heading up ('HDG Up') aligns the top edge of the map display to the current aircraft heading.

The range arc includes tick marks indicating compass directions. Track Up indicates current track with a tick mark on the outside of the arc. Heading Up indicates current heading with a heading lubber line, and the heading bug and reference line are displayed while the heading is being adjusted, and remain displayed for three seconds after the last adjustment.
