Waypoint arrival circle
The NEXT WPT screen and acknowledgement occur within a circle around the
actual waypoint (and hence a distance from the next track leg). If you have
manually changed the default waypoint arrival circle value to 0.3Nm or greater this
can result in a cross track error alarm and associated course correction.
Refer to
Cross track error
on
page 27
for more details.
Steering to the next waypoint in a route
When the Waypoint Advance warning sounds, the SmartPilot suspends Track
mode and maintains the current boat heading.To advance to the next waypoint:
1. Check that it is safe to turn onto the new track.
2. Press the
TRACK
button. This will cancel the Waypoint Advance warning and turn
the boat towards the next waypoint.
Note:
If you do not press
TRACK
to accept the Waypoint Advance, the SmartPilot will maintain
the current heading and continue sounding the warning.
Skipping a waypoint (SeaTalk chartplotters only)
If you want to advance to the next waypoint
before
you have arrived at the target
waypoint, you can skip a waypoint by pressing
TRACK
for 1 second. The display
will then show the Waypoint Advance screen for the next waypoint. Check it is safe
to turn, then press
TRACK
to turn the boat towards the next waypoint.
