Chapter 3: Advanced Operation
The autopilot takes account of vessel speed when computing course
changes to ensure optimum performance over a wide range of vessel
speeds. If speed data is available, the ST5000 Plus uses the measured
vessel speed. Otherwise, the Speed Over Ground (SOG) or specified
cruise speed is used, depending on the calibration setting (see Dealer
Setup in Chapter 4).

Arrival
As the vessel arrives at the target waypoint, the navigation receiver
should select (manually or automatically) the next target waypoint.
The ST5000 Plus detects the new target waypoint number, sounds the
Waypoint Advance alarm and displays the Waypoint Advance
information. This display shows the new bearing to waypoint and the
direction the boat will turn to acquire the new track.

To accept to the new target waypoint, press track.
Note: When you reach the last waypoint in the track, the NO DATA
alarm will sound to indicate that there is no further waypoint
information. Press auto to continue on the same heading, or standby to
return to hand steering.
