Automatic Steering - Simrad AP35 Instruction Manual

2.9 Automatic Steering

The AUTO mode is used to make the AP35 steer the boat automatically on a
set heading. AUTO is always available from any mode or function within the
AP35 by a single push on the AUTO button. When the AUTO mode is
selected, the AP35 automatically selects the current boat heading as the set
course and the current rudder angle to compensate for wind/current.
Note !
If Init Rudder "Midship" is selected (see Dockside settings, page 73 the
rudder will move to midship (0
In AUTO, the AP35 is issuing rudder commands to keep the boat on the set
heading. Determination of the boat heading is provided by the magnetic
compass course detector or RFC35 Fluxgate Compass (or an optional
heading sensor) for course keeping in AUTO mode.
The AP35 will keep the boat on the set heading until a new mode is selected
or a new heading is set with either the course dial or the PORT or STBD
buttons. One revolution of the dial equals 45° course change.
Once the course is changed to a new set heading, the boat will automatically
turn to the new heading and continue to steer straight.
