In order of preference, the autopilot uses:
•
measured boat speed (speed through water)
•
if this is not available, it uses the speed over ground (SOG)
•
if this is not available, it uses the cruise speed specified in Dealer
Calibration (see page 95)
Waypoint arrival and advance
Note: Waypoint advance only operates if the ST6001+ is receiving
valid bearing to waypoint and waypoint name information.
Arrival
As the boat arrives at the target waypoint the navigation aid will select
the next target waypoint and transmit this to the autopilot. The
autopilot will then detect the new target waypoint name, sound the
Waypoint Advance warning and display the Waypoint Advance
(NEXT WPT) screen. This shows the new bearing to the next waypoint
and the direction the boat will turn to acquire the new track.
