Introduction
NAC-D autopilot computer
NAC-D is the Autopilot computer to supported EVC steering
systems.
Autopilot controllers
The NAC can be controlled by various Simrad control units. This can
be dedicated autopilot controllers, Multifunction displays (MFDs)
and autopilot remote controllers used in combination with
instrument systems, or any combination of the above.
Autopilot functions
The autopilot computer supports a large range of automatic
steering modes. Not all autopilot controllers have access to all
options. E.g. autopilot systems including only an autopilot remote
controller (without display) do not have access to turn patterns.

The autopilot functions are presented slightly different on the
different displays.
This manual shows screen examples from both MFDs and AP48.
Autopilot computer setup
When the autopilot installation is completed, the setup of the
autopilot computer must be performed. Failure in setting up the
autopilot correctly may prohibit the autopilot from functioning
properly.
The setup of the autopilot computer is divided in two main steps:
• Installation settings

setup" on page 12 and "Sea trial" on page 16

preferences. See "User settings" on page 23
