3.2.2 ADVANCED AUTO mode
AUTO mode will maintain a set course, but your vessel’s course may be shifted
by the effects of current or wind. ADVANCED AUTO mode maintains a set
course while compensating for the effects of wind and tide. Note that your
NAVpilot-511/520 must be connected to a (GPS) which outputs own ship’s
position data (L/L) in NMEA0183 format to the NAVpilot-511/520.
In the ADVANCED AUTO mode, the NAVpilot-511/520 will calculate your course
based on your present position and heading, and by setting a virtual “waypoint”
in its memory to navigate towards. If either tide or wind begins to push you off
course, the NAVpilot-511/520’s processor will correct your heading accordingly.
In this mode, “AUTO” appears on the display.
