Steering Modes of the System

Note that all steering related functions are available only if the ECDIS system is also connected to an optional
Yokogawa PT-500A autopilot processor.
With Yokogawa PT-500A autopilot following steering modes are available:

• Hand steering (Mode selector: HAND)

• Autopilot steering (Mode selector: AUTO)

• Track mode automatic Route steering (Mode selector: NAVI)

Note: to use any of above steering modes SYSTEM STEERING SWITCH must be switched as FU (Follow Up).
29.3.1 Hand steering (Mode selector: HAND)
Switch Steering mode selector to "HAND".
While in hand steering mode the ECDIS system displays the rudder angle and indication of steering mode.
29.3.2 Autopilot steering (Mode selector: AUTO)
Autopilot steering mode:
• Operator sets the required heading of the vessel using "Heading Setting Dial".
• Turns are controlled by the rudder limit
• Turn is initiated by operator
While in Autopilot steering mode the ECDIS system displays the rudder angle and indication of steering mode. The
Curved EBL is not available because the use of it requires radius controlled turns.
29.3.3 Track mode automatic route steering (Mode selector: NAVI)
The ECDIS system will follow the planned track to next waypoint but with a moderate accuracy in order to have
more economic sailing (sailing in ocean areas).
When approaching the next waypoint the system is pre alerting operator well before the turn and just before the turn
a second acknowledge is required.
The ECDIS system performs turns using planned radius.
