Using the Autopilot After an authorized marine technician has installed the control head and equipment, configured the control head, and then tested all equipment, the autopilot may be used in open water. Operation Modes: Introduction The autopilot has several operation modes that allow the autopilot to steer the vessel. Operation modes are also determined by the optional-purchase equipment connected and enabled in the autopilot system. You will learn how to apply each operation mode on the following pages.
The autopilot navigation modes are briefly described here. Proceed to Navigate with the Autopilot for more information. • Standby: (Press the STANDBY/POWER key) During Standby mode, the autopilot is not controlling the vessel. Be prepared to control the vessel manually before initiating Standby mode. • Auto: (Press the AUTO/TRACK key) Auto mode uses a compass to navigate towards the set heading. You can also choose a turn pattern and tack (with an optionalpurchase wind sensor) in Auto mode.
Multisensor Technology Your SC 110 Autopilot uses multisensor technology. Several sensors can be connected to the autopilot system, and you can select the active sensor. The attached sensors also determine which operation modes are available on the autopilot system. The Gyronav Rate Sensor is always active when it is attached to the system. Multisensor Icon: When an M is displayed above the active sensor icon on the screen, Multisensor mode has been enabled.
NOTE: If a black-out of the GPS receiver occurs, the autopilot will maintain the set course by using the compass as back-up. Sensor Alarms: If a sensor is unavailable, the system will display an alarm. For example, if the vessel is traveling slower than 4 kts in Auto-Track mode, the GPS icon will flash on the screen to indicate that the GPS COG (Course Over Ground) is not as accurate as the compass. In this case, you should switch to Auto mode.
Default Display The screen display shown here is shown when Standby, Auto, Auto-Track, Nav, and Follow-Up mode are active.
1 Heading: Red line indicates the heading of the vessel on the analog compass. 2 Compass: Analog 3 Operation Mode: Indicates the current operation mode. 4 Starboard icon: This icon will flash to indicate when the control head requires a tack direction. 5 Information Display: SOG (Speed Over Ground) or COG (Course Over Ground) will be displayed here.
