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
