Simrad AP25 Autopilot

2.13 NoDrift
The NoDrift mode is an alternative to route steering in NAV
mode, and is automatically entered when you press the
NAV WIND button provided NoDrift has been selected in the
(user) SETUP menu (page 38).
The autopilot will steer to an imaginary waypoint and the
bearing is the boat’s heading at the very m
oment the NoDrift
mode is engaged.
Unlike when in Auto mode the vessel will steer a course equal to
the bearing line unaffected by wind and current (no drift).
The course to steer to (bearing line) can be changed the same
way as when changing course in Auto mode.
Select NoDrift in the Setup menu
when in STANDBY or AUTO
mode. Press the NAV WIND button
to enter NoDrift mode. The NAV
WIND key is now programmed to
always activate the NoDrift mode. If
you want the key to activate NAV
mode, enter the User Setup menu
and select NAV.
