ST60 Graphic Display Operating Guide
How is data presented?
The ST60 Graphic Display pages show either 1, 2, 3 or 4 data elements in
alphanumeric form. In addition, single-element pages can also show graphic
information, such as a rolling road.
Rolling road
The rolling road is a representation of your vessel’s position with respect to a
waypoint, and a steer bar shows the direction you should steer to achieve the
required course. The number of arrows in the steer bar is proportional to the
amount of cross track error; each arrow represents 0.05 nm of error.
The direction of the roll indicates whether you are moving towards or away
from the waypoint. A small boat graphic indicates the attitude of your boat
with respect to the waypoint.
Cross track error (XTE) information, bearing to waypoint (BTW)
information and distance to waypoint (DTW) information are displayed with
the rolling road.
Graphs
You can see the history of some information by displaying it as a graph, of
data against time. Refer to the
