1.7RF300 Rudder Feedback unit
Rudder feedback unit with transmission link and 10 m (30 feet) of cable. Transforms the angular travel of the rudder to a digital signal read by the autopilot steering computer.
1.8Heading Sensors
The AP26 and AP27 autopilots can be used with the following combinations of heading sensors:
RC36 Rate compass
Fluxgate compass with integrated rate sensor. Provides a dramatic improvement to the dynamic performance of both the autopilot and a stabilized radar display.
RC36 comes as standard with the autopilot.
RFC35 Electronic Fluxgate Compass (optional)
A compact heading sensor from Simrad with 15 m (45 feet) of cable. The direction of the earth's magnetic field is sensed by a
