ST1000 Plus & ST2000 Plus Tiller Pilots
Tidal stream compensation
Under most operating conditions, Track mode will hold the selected track to
within ±0.05 nm (300 ft) or better.
The autopilot takes account of the boat’s speed when computing course changes
to ensure optimum performance over a wide range of boat speeds. If speed data
is available, the autopilot will use the measured boat speed. Otherwise it will use
the default cruise speed entered in Calibration Level 5 (see
page 62
).
Waypoint arrival and advance
CAUTION:
Waypoint advance will only operate if the tiller pilot receives
valid bearing to waypoint and waypoint name information.
The tiller pilot can only decode the first FOUR characters of a
waypoint name. It will not be able to decode names longer than
four characters, which will stop the waypoint advance feature
from working.
If your navigator transmits valid waypoint name and bearing to waypoint data,
you can advance from one waypoint to the next by pressing
-10
and
+10
together.
