ComNav 1101 Autopilot5 - 12 GETTING STARTED
Sea Trials
You are now ready for Sea Trials which is the second part of the
setup process. The Sea Trial procedures in this “Getting Started”
section complete the basic setup of the Autopilot and must be done
before attempting to operate in AUTOPILOT or NAV modes. You will
find more Sea Trials procedures at the end of the “Basic Operation”
section and the “Advanced Operation” section.
Be sure you read all the procedures before commencing Sea Trials,
and follow the Setup and Sea Trials Checklist so as not to miss any
steps. Sea trials should be performed in relatively calm seas away
from obstacles and other marine traffic.
Fluxgate Compass Compensation
If your Autopilot was supplied with a ComNav fluxgate compass, it
must be “compensated” to eliminate the magnetic distortions from
the vessel’s environment. This is done electronically through a
process called “auto-compensation”. If you are using a magnetic
compass or self-compensating Fluxgate compass, skip this proce-
dure altogether.
1. Begin with the Autopilot turned off.
2. Perform a (normal) “Reset” as described at the beginning of
this chapter. The display will show:
5. The second line “Fluxgate Compass” should be flashing. If not,
use the ADJUSTMENT KNOB to select “Fluxgate”.
3. Select “Set up compass” by turning the ADJUSTMENT KNOB
clockwise one position. The words “Set up compass” will start
flashing on and off.
4. Press the SPEED button once and the display will change as
shown here:
If your Autopilot system
includes a ComNav
Heading Rate Stabilizer
(HRS), skip the Fluxgate
Compass Compensation
completely. Follow the
autocompensation
instructions that accom-
pany the HRS.
Make sure your vessel is
well clear of any ob-
stacles and other marine
traffic before commencing
Sea Trials.
