EMRI FAP-2000, FAP-3000

The FAP-2000, FAP-3000 receives position, heading and speed data, compares them
with the track section to be steered, and applies that information to calculate and com-
mand the necessary rudder angle.
Hand (manual) steering modes
The following hand steering modes are available without the autopilot: Steering wheel,
Wing steering control, and Override tiller. While in a hand steering mode, the ECDIS
indicates the rudder angle and the hand steering mode.
Autopilot steering modes
The autopilot steering modes are selected from the autopilot control panel.
Heading control mode
The autopilot steering modes are selected from the autopilot control panel.

lights.
• Immediate course change when the tiller is used to set the heading.
