In the FULL mode a 360 degrees compass rose and ILS or VOR information are displayed.
In the ARC mode a forward segment of 90 degrees out of the compass rose and the same
information as in the FULL mode are displayed.
In the MAP mode VOR (navaids) and FMS information (waypoints) are displayed at the 90
degrees compass rose segment. Weather radar system data can be superimposed in the
ARC or MAP mode.
