System information
32 | Operation
The prompt display shows the name of the next waypoint
(WP), the bearing of the track line (BWW) from the
previous waypoint to the destination waypoint, the
required course change (CHG) and the direction in which
the boat will turn.
If only one waypoint has been entered the bearing will be
from the present position to the destination waypoint.
• NAV mode
• Course to steer (CTS): 014 is
set internally by the autopilot
to steer the boat onto the track
line and maintain the bearing
• Cross Track Error (XTE): 0.014 nm
• Boat symbol illustrating whether the boat is to port or
starboard of planned track
• Compass heading: 345° M
• Next waypoint: Eigeroy
• Bearing to next waypoint (BTW): 014°M
• Distance to next waypoint (DTW): 124.7 nm
• Steering parameter: HI-A
For Cross Track Error, the number of decimals shown
depends on the output from the GPS/chart plotter. Three
decimals give a more accurate track keeping.
When operating the AP24 in NAV mode to steer through a
route of waypoints, the AP24 will steer to the nearest
waypoint in the direction of the route after you accept the
NAV mode prompt. When you arrive at the waypoint, the
AP24 will output an audible warning, display an alert
screen with the new course information, and
automatically change course onto the new leg.
If the required course change is more than the NAV
change limit (default 10
°
), you have to verify that the
upcoming course change is acceptable. This is a safety
feature. See page 69 on how to change the ‘NAV change
limit’.
