Numerical indicator and markers are displayed in following modes only:
– DP Mode (Auto Heading, LS Track and Target),
– AP Mode (Auto Heading /HS Track).

on the scale.
A range value is set by operator in HGD page of the Param window (see Section 5.9, page 85).
Off-Heading Limit Excess Off-Heading Limit indicator becomes red-colored in case a value of heading error exceeds a
value of Off-Heading Limit.
The indication disappears as the deviation is less than a half of Off-Heading Limit.
This indication is provided only in Auto Heading mode.
NOTE!
Heading Error Heading error indicator displays the deviation from the heading setpoint. 'S' means starboard, 'P' -
portside.
Yaw Rate Yaw rate indicator displays a value of yaw rate and its direction. 'S' means starboard, 'P' - portside.

Position Error, Auto Position Mode Indicators display the deviation of a vessel from Set Position.
The left Position Error indicator displays the deviation in the surge/north axis.
The right Position Error indicator displays the deviation in the sway/east axis.
Data is displayed depending on a Map view selected in View page of Param window(5.9, page 85):
– View: REL the deviation is displayed in vessel coordinates.
For left indicator: 'F' means forward, 'A' - aft.

– View: TRUE the deviation is displayed in geographical coordinates.
For left indicator: 'N' means north, 'S' - south.
For right indicator: 'E' means east, 'W' - west.
