B&G Zeus2 Glass Helm CPU - Manual (Page 54)

Turn pattern steering
The autopilot includes a number of automatic turn steering features for power boats when
the pilot is in AUTO mode.
Ú Note: The turn steering option will not be available if the boat type is set to sailboat - instead
the tack/gybe feature is implemented.
Initiating a turn
You start the turn by selecting the relevant turn icon, followed by selecting the port or
startboard options in the turn dialog to select the turn direction.
Stopping the turn
You can stop the turn from within the turn dialog.
You can also at any time during a turn return to STBY mode and manual steering from the
autopilot pop-up.
Turn variables
All turn steering options, except the C-turn, have settings that you may adjust before you
start a turn and at any time when the boat is in a turn.
U-turn
U-Turn changes the current set heading to be 180° in the opposite direction.
The turn rate is identical to Rate limit settings. This cannot be changed during the turn.
Ú Note: Refer to the separate Zeus 2 Glass Helm Installation manual for information about Rate
limit settings.
C-turn
C-turn makes the boat turn in a circle.
You can adjust the Rate of turn from the turn dialog before the turn is initiated and during
the turn. Increasing the turn rate makes the boat turn a smaller circle.
Spiral turn
Spiral-turn makes the boat turn in a spiral with a decreasing or increasing radius. This feature
may be used for circling fish or when searching an object.
You set the initial radius before the turn is initiated, and the change per turn during the turn.
If the change per turn is set to zero, the boat will turn in a circle. Negative values indicate
decreasing radius while positive values indicate increasing radius.
Zigzag turns
For navigating in a zigzag pattern, you set the initial heading change before the turn is
started.
During the turn you can alter the main heading, the heading change and the leg distance.
Square turn
Square-turn makes the boat automatically turn 90° after having travelled a defined leg
distance.
You can at any time during the turn change the main heading and the distance of the leg
until the boat makes a new 90° turn.
