If the vessel is equipped with a thruster, it can be connected to 
the AP50 system and the vessel can then be controlled by 
rudder, thruster, or both rudder and thruster.  
After connecting a thruster to the autopilot system (see the TI50 
manual) the thruster type must be selected under the Installation 
Dockside menu (see page 126). 
A thruster icon below the mode index indicates that a thruster is 
connected to the system. 
Now you can select one of three control functions from the User 
Set-up Menu: 
•  Rudder: The rudder is used to maintain the heading (always 

in AUTO mode and NAV mode). 

•  Thruster: The thruster is used to maintain the heading (only 

in AUTO-WORK, NAV-WORK, Follow-up, and Non-
Follow-up steering modes). 

•  Rudder and Thruster: Both rudder and thruster are used to 

maintain the heading (only in AUTO-WORK mode, NAV-
WORK mode, Follow-up and Non-Follow-up steering 
modes).
