• The navigation receiver must be operating and the navigation
system (GPS/Chart plotter or ECS) must be in full operating
mode with adequate signal characteristics for valid position
and steering data
• At least one waypoint must be entered and selected as the
current waypoint in the navigation receiver
• The navigation source in the AP50 User Set-up menu must be
set for the navigator that contains the current waypoint
The AP50 is designed to steer in mixed mode operation. This
combines the straight steering capability of Cross Track Error
(XTE) steering in conjunction with the turning capability of
bearing mode steering (Course To Steer [CTS]).
Press the NAV button to activate the NAV prompt display.
The upper half of the prompt display shows the name of the next
waypoint (WP), the bearing to the waypoint (BWW), and the
required course change (Chg) with the direction in which the
vessel will turn.
The lower left portion shows the compass heading and the lower
right portion shows the rudder angle and port direction.
Press NAV to accept the first waypoint as the location to steer
towards. The autopilot turns the boat onto the new course.
Display information:
• NAV mode
• Course To Steer (CTS): 340° is set internally in the autopilot
to steer the boat along the track
• Nav source: GPS1. The boat is located on the track
• Cross Track Error (XTE): 0.000 nautical mile
For Cross Track Error, the number of decimals shown
depends on the output from the chart plotter. Three decimals
give a more precise steering than two. Four decimals from
chart plotter are shown as three decimals on the display.
• Compass heading from Gyro1: 340.7°
• Next waypoint: Simrad
• Bearing from the current position to the next waypoint
(BPW): 340°
